So you are a loyalist marine captain (chapter of your choosing). You have the knowledge and hindsight of every event that has occured upto the current timeline. You can make one time jump to influence history (forget the whole logic of changing history means you cease to exist so therefore couldn't have made the time jump in the first place).
When you arrive, you have no time to explain anything to anybody but must jump straight into action. So no going to Calth ahead of the Word Bearers and making the Ultramarines ready for the coming attack.
The there are three systems inaccessible to your time travel device. The Sol system the Davin system and the system of the homeworld of the Interex.
Where would 100 marines with the knowledge of hindsight make a massive difference to the timeline that will benefit the Imperium?
Where and when would you go?

Jump back to the fight between Horus and the Emperor. Wreck Horus'

And I realised I can't go to the Sol system... because arbitrary nonsense...

No jumping to the Sol system.

Reason I put that in was because the 3 or 4 obvious answers are: fight between Sanguinius-Horus/Emperor-Horus, Conversion of Horus or Erebus' theft of the weapon that will convert Horus.

We all know those will be the most effective times to travel to. So when else will be a time where 100 marines greatly change the timeline?

I would stop the creation of Men of Iron -> Dark Age of Technology would propably never end/end later -> Heresy Might not happend at all -> Technological superiority -> Imperium Wins

Step 1: Move a planet out of its orbit, some time reeeaaaally long ago

Step 2: Have it hit Terra just before the HH reaches Terra, but while Mr E is still there.

Step 3: Emprah Horus.

But that's me.

As a loyalist, have it hit Horus at some point.

Second option, Kill Kor Phaeron and Erebus before they convert Lorgar, or stop Magnus from psychic telephoning Big E

Kill hitler... ehm sorry kill the emperor before he was born.
He is an abomination and his empire is a shadow of what humanity could be.

If I was loyal to the empire then I would have taken 100 relictors and have rescued Adept Zeth, Dalia Cythera and the unfinished Akashic Reader and shipped it to my cruiser before the hell broke loose on mars.
This could even explain why no one has seen the relictors any more.

Killing those two seems to be the best option, but who knows if the chaos gods had a back-up plan (they most certainly had, but well). Another big problem is also the "time travel as a vision that occured for Argel Tal and the Seated Sun Chapter (and also Horus IIRC) which f*cked everything up. If we kill Erebus It could create an infinite time paradox, since Argel Tal would never have split the primarchs accross the galaxy, and therefore Lorgar would never have ended on colchis, and therefore² wouldn't have led to Erebus becoming what he was, and thus make it impossible to kill him with our initial time travel.

What? We kill Phaeron and Erebus and Argel Tal doesn't go back in time?

Go to the Laer Worlds and remove the sword so it can never corrupt Fulgrim. Fulgrim and the Emperor's Children remain loyal, the twin Isstvan battles are not nearly as devastating, Ferrus Manus doesn't die, the Eldar may establish diplomatic contact with the Imperium courtesy of Fulgrim, and because Fulgrim doesn't become a Daemon Prince, Guilliman doesn't die either.

I was trying to come up with a way to change Istaavan and this works better than what I had.

There's always a chance Slaanesh would come up with an alternate way to corrupt Fulgrim.

Assuming the butterfly effect, no he, she, it wouldn't have a different plan.

Assuming the "Time corrects itself" theory, Slaanesh would still corrupt him.

Mantis Warriors.

Gorro.

Assassinate Horus while he's watching the Emperor bloodline-purge the Ork Prophet.

What if you removed the very first eldar pleasure cult

By this way slaanesh may never exist?

Humanity may have a changed future but no reign of chaos?

Horus really is the linchpin here. The Chaos gods would inevitably develop additional plans after the loss of people like Erebus or Kor Phaeron, but Horus is the only one I can see being able to put the Emperor in his corpse-state. I just don't see the Emperor holding back as much against the other primarchs like he did against Horus. So even if the heresy still happens in some form or another, if the Emperor is still walking around afterwards then it is a net win for the Imperium.

Hm. Take them on a coach trip to 1970s Blackpool pleasure beach and promenade, and enjoy the seaside. We'd have to argue to get them on some of the height restricted rides.
Take them in the ballroom after, and maybe see a show.

Tell me they don't deserve it.

So you can travel back in time but not in time to get in a quick conversation to let people know what the hell is going on?

I would go back to the start of the golden age of mankind, to one of the core human worlds and lay out to the locals the world of poop that is going to go down and hope to change things

I like this. I would use Iron Hands to do it.

Or maybe take the Space Wolves back to the Vikings game today and replace the Vikings players with the Space Wolves.

If I have to keep it in the world of 40k I'd say take the Iron Hands led by a Iron Council back to prevent the death of Ferrus. That was one of the most disgraceful, pathetic death's ever. Or maybe just make sure Kardan Stronos is aborted as a baby.

My top picks for what to do with them:

Have the 100 marines wipe out the Cabal reaching out to the Alpha Legion to prevent them from fragmenting into all the various factions that occur in the Heresy (or at least have them ostensibly stay on the loyalist side).

Have the 100 marines stop Lorgar's attempt to commune with the Chaos Gods when he's on Cadia, backing up the lone Custode that accompanies them on the surface and either taking Lorgar out or at the very least hindering the ritual (presuming I'm taking Grey Knights here).

Yeah, hard to figure out why you wouldn't in most cases, short of you trying to do something directly against the sisters of silence I can't see any other chapter outmatching them.

Aside from some of the obvious, how about stopping the Death Guard from making their fateful Warp jump?

Or warn Guilliman he's being tricked into being too far away to be of use?

Either of those legions joining the main fight against Horus would have been a very big deal.

(I'm not totally all for genocide, I'm sorry)

Considering the sheer power both technological and Psychic the pre-Fall Eldar Possessed I don't think it'd work that well.

Wyzilla wrote:Considering the Eldar Pleasure cults were started by a Greater Daemon of Slaanesh, good fething luck with a Company of Marines.

Where's that from? Slaaneshi Daemons being involved before Slaanesh's "birth" seems like something GW would do but I'm curious as to the source.

Grimskul wrote:Yeah, hard to figure out why you wouldn't in most cases, short of you trying to do something directly against the sisters of silence I can't see any other chapter outmatching them.

Space Wolves, obviously. They can wage open war on anyone and get away with it.

On a more serious note, Deathwatch Marines would also be very potent but generally I think Grey Knights have the advantage.

Stopping Goge Vandire or the Beast earlier might help. Ensuring the security of that STC which could cure various diseases that the Dark Eldar (Panacea Wars I think) stole could likewise have huge ramifications. Aside from that apparently in Monastery of Death which leading the Imperium to earlier would be of great use.

Hayley Williams wrote:Time travel to the original Tau home planet and wipe out the early fish/frog/whatever people.

Lol. Could wipe out the Necrontyr instead. No C'tan, no Necrons, no Orks, no Eldar Old Ones still around. Would that be a good thing? For humans I mean.

It's a fun idea this. I'd Definetly pick the ultramarines first Company, go to the necrontyr homeworld and utterly wreck it. Then I would laugh and laugh and laugh as the Space marines will never be created and the Eldars and orks never had to be spawned.

If you want a smaller scale of change in events then probably grab 100 lamentors and travel back in time to some pivotal moment and reinforce them. The manliest chapter of them all.

Too Tanith before Chaos invaded., help but more time fr the other two Regiments to get off world. Fluff wise imagine the sabbat crusade if Guant had two more regiments under his command.

I mean really, bigger fish man, think bigger than Tanith.... I'd kill Horus for sure, as this would likely change the Heresey, or try and alter some other important thing, like Isstvan as that would have a huge impact on the IoM in the long run.

Judging by how some of the Horus Heresy books have been portraying things I'm not sure a single company could take out Horus even if he was on his own for some reason.

Should you could try it whilst he's a baby but that didn't work out too well for the Eldar\Dark Eldar who tried it on Angron.

Leave Horus and take out those who plotted against him and the Emp would be my view.

Pretty sure my 100 marines could kill baby horus... or kidnap him and replace me as horus.. hmmm that would be great.

He never leaves Terra, so...

In terms of benefitting the Imperium as a whole, would it be worth going back and taking out Gorg Vandire before he gets to power?
According to the fluff the HH lasted around10(?) years, the AoA lasted over 70.
It did absolutely untold damage to the Imperium in terms of resources, territory, dealing with xenos etc.

Or in a similar vein taking out Abaddon before his 1st Crusade? Would have saved a lot of headaches over the years not to mention again resources and forces to deal with other xenos.

Just a thought.

Go back in time, and stop me from marrying my ex-wife.

No, wait, that's on Terra.

Oh, go back in time to whatever alien planet my ex-wife is from, and kill her at birth.

No, wait, 100 marines are no match for my ex-wife.

Dang, this is a hard one.

I'd make sure they were War Hounds and have them save Angron from having the Butchers Nails implanted. Then conquer the world.

I love the Warhounds and would like to see how they would've been if they didnt have a broken primarch

Jump to baby Horus just after he has landed, kill him, save the Imperium.
Alternatively, for great hilarity, jump incredibly far back in time and stop the Old Ones from ever evolving.

Ullanor, just after the Emperor declares Horus Warmaster and leaves. Deploy onto one of the (many) orbiting major capital warships with a company of astartes, size control of the primaris weapons array and hit the world with multiple exterminatus weapons.

It's the one point that Lorgar, Horus, Fulgrim, Magnus and Angron are all within a ten-foot area above ground during the Horus Heresy....

...Granted, Dorn, Sanguinius and Khan are there too. Sucks to be them, I guess.

Hmm, there are lots of good possibilities of what could be done, but Im gonna choose...

Take my Marines and myself to Nostromo, to where Curze lands, shortly after he does, so we can get him before he wanders off on his own. Then we can help guide him down the right path.

Vandire was an opportunist. The Age of Apostasy actually predated his reign. What's needed is to kill the three Ecclesiarchs before Vandire. Alexis XXII, I think.

It's simple really...we kill the Batman...

Or alternative view. A lot of people are using their time travelling marines to help in battles or assassinate key figures. What if I took my marines on a supply gathering mission and kept them out of harms way? Example: Go back to Dark age of Technology spend the whole time stockpiling STC designs and tech (while learning how to actually work the damn stuff properly). As the Age of strife approaches I grab a fully functioning STC machine and whisk it away nice and safe guarded by my now techno savant marine company. When the Age of Strife ends I warp into Terra end the Unification wars overnight and secure Mars for myself (they would either treat me as a God or bow down before my superior weapons). Keep the big E around as I do like him but we could skip the whole space Marine legion thing and carry out the Great Crusade with normal humans wielding incredible weapons of war (titans, titans as far as you could see!). In order to protect my preserved technology I would utilize the lost technological arts of ctrt. c and ctrt v to make sure losing one stupid forgeworld doesn't mean losing entire freaking designs Great crusade would end quickly and with a higher tech base. No primachs, no fallen Big E (although he is less needed) no Hours Hersey. Humanity develops the human webway project uninterrupted eliminating the need for warp travel. Finally, I wipe out any Xenos race that even looks funny at me. Humanity would awake from the the horror of the Age of Strife to a new brighter tomorrow of science, reason and trust instead of superstition, religion and hate.

That's how I would do it.

Go back in time, and inform Russ of Horus's treachery, have irrefutable proof. Suddenly thousand suns and wolves team up and help kill Horus. The emprah never gets gravely injured.

Take my Marines and myself to Nostromo, to where Curze lands, shortly after he does, so we can get him before he wanders off on his own. Then we can help guide him down the right path.

Im not sure poor old Curze could have been saved. Its possible whatever intervention happens would see him degenerate anyway.
Its not that he actually believed Horus or backed his ideals, he just loathed the hypocrisy of the Emperor and the Imperium more. That and his self loathing are powerful drivers.

Curze's whole situation was because he had to fend for himself. He loathed the Emperor and his Hypocrisy, but did nothing to change his Legion, which fed the cycle and led to his Legion being singled out for its crimes.

That could easily be avoided.

You teach him, bring a Librarian to help guide him with his powers. Show him how social interactions work.

Or a few good spanks on his bottom.

Naturally, that comes with the whole guiding him thing.

Which would, IIRC, lead to Primarchs not scattering, which in turn would lead to all Primarchs being raised by the Emperor and taught about the dangers of warp, and resulting in the success of Great Crusade.

It could work.

If you had a working STC database, you would also have non-Warp FTL, as the Speranza in Priests of Mars has one integrated into its Machine-Spirit (which promptly gets wiped from the Magos's memory who discovered it by the Omnissiah, of course. Omnissiah turns out to be a total scrub), and has non-Warp FTL systems.

Curze might have been better off than Angron though. Angron definitely needs the help more.

*deleted. I didn't follow the rules.

Save. The. Squats.

There was a story in the Chaos Codex about a Priest that said a bunch of Space Marine Chapters were tainted and needed to prove they weren't tainted by going headfirst into the Eye of Terror to fight daemons and CSM.

Well as you may have guessed, most of them fell to chaos. Or just straight up got wiped out. But a handful survived and made it back safely about 800 years later.....Only to learn that Priest was still alive and kicking. Turns out he was a Chaos Worshipper and the remaining Marines turned him into swiss cheese when they found out.

If I had 100 marines, I'd go after that guy before he declared a ton of Chapters to be "Tainted".

Travel to Emperor when he was out of sol system in first time. Then tell him all what will happen or he could just read my mind.

- Trust in the Emperor -

Probably go back and try to stop the necrons from becoming all metally or something. probably would have saved a lot of trouble!

Or go to Cadia, wipe the slate clean, and make sure whatever chaos nonsense doesn't happen there.

1. Loot my chapters Armoury and give everyone a plasma gun. Then every suit of artificer armour I can muster put on them.pilfer the Iron halos from the rest of the chapter and stick them on my dudes. Pick up a Leviathan Dreadnought from the Armory and kit out my devastator squads with grav cannons (20 grav cannons, 4 cannons per team be damned)

2. Warp to the battle of Phall, tell Alexus to KEEP HAMMERING THE IRON WARRIORS. The heretics are not at terra yet, and if he withdraws he will lose too many men, and if he kills perterabo the better.

3. Get back to terra and demand a psychic choir be created to send an incredibly strong astropathic message to Guilliman to get the hell back to Terra, without everyone taking a pit stop at Ultramar they are easily able to repulse the heretics and immediately begin the scouring with the emperor alive.

I would give Saul Tarvitz support on Istvan V, just after the virus bombs.

Port back to the Luna Wolves fleet (some random point int eh Galaxy while they're on the Great Crusade), pick the second biggest ship's bridge, take it in a flash, and then broadside Horus's Flagship, along with the majority of his attendants and consuls.,... let's forget about all the secondary casualties.

Bye bye Heresy.

I would travel to Mars right before the Civil War (Schism of Mars).

100 marines in the right spot at right time could save an unfathomable amount of data and technology.

Off the top of my head -
Designs for the Akashic Reader (That could be worth more than everything else right there)
Fully functioning STC templates, with backups, for the most important equipment/vehicles known at the time (Solar Auxilia, the awesome tanks such as the Sicaran etc. etc. all the best tech that was lost)
Rescue some of the more important (non-corrupted) Tech Magos' with the knowledge to rebuild successfully.

That would change the entire path of the Imperium after the Heresy;
With the Akashic Reader - Game over, Imperium wins.
Without the Akashic Reader - The STC's and uncorrupted Tech Adepts would allow the Mechanicum to produce and maintain ancient and powerful technology, even keeping the Imperial Guard as the Solar Auxilia (with the accompanying tech).
The uncorrupted Tech Adepts would have also instilled a desire for progress and scientific advancement/innovation instead of the current stagnation.

Well then, feth it.

I'd go back to Alpha Centauri at the time of Ancient Egypt and then go over to Terra, grab people from across the globe (not enough to damage population growth) and then seed colonies across the galaxy. Rinse/repeat as many times as I could in order to spread humanity as far as possible as early as possible.

The colonies would be informed about the Warp, Chaos Powers and then told how to prevent corruption. They would also be given a timeline of events to prepare for such as the Age of Strife and the coming of the Emperor.

The colonies that appeared to be prospering the most or were in strategically important locations (Cadia etc.) would be given a marine each, in order to protect them from corruption and to foster technological advancement without the restrictions of religion.

This is about ~25,000 years before, in the current timeline, humanity colonised the stars. Therefore, I'm betting that multiple more colonies spread throughout the Galaxy and potentially faster developing (lack of religious dark ages and support from the marines) would lead to a much greater Human presence and greater mastery of technology before the Fall of the Eldar (which they would have hopefully prepared for).

After that, events become too difficult to predict due to the radical change in the timeline.

How do you know that didn't already happen to ancient Egypt in our time-line?

Could have been the Thousand Sons, we just didn't listen

Haha, actually plausible --- well done!

Going from the inevitability of the Heresy (Horus gets corrupted. If you prevent that, the gods will find another way/choose someone else), I'd say foiling "mortal" plans would be the way to go.

Remember Erebus doing gak on Calth summoning the Ruinstorm?
Have the 100 not only warn Calth of the incoming threat, blunting the ambush, wrecking the Word Bearers, but have them hidden in Ambush on the plateu where Erebus does his thing.
Vaporize him with about 5000 Bolt rounds.

No Ruinstorm.
Ultramarines, Dark Angels etc. not locked in Ultramar.
Free Warp Travel. No economic and logistic decline. Reinforcements galore for Terra.
No need to board the Vengeful Spirit.

Heresy ends badly for Horus. Emp walks. Galaxy saved.

Go back to the HH with my 100 Red Scorpions all clad in MK4 power armour (so we wont be instantly targeted apon)
Obtain a Leviathan Siege Dreadnought
Paint Said Dreadnought Red
Wait until Horus fights the Emperor
Get said dreadnought to smash into the room shouting "OH YEAH!"
After this, locate Orikan the Diviner
Ask if i can 'Borrow' his Time Machine
Return to the present

So I know every event from the creation of the universe to the 41st millennium huh and the idea is to go big and change history… well lets go big and I don’t need marines…I think.

This basically assumes that Eldar mythology is true…I go back in time to the creation of the Eldanar where the Gods walked amongst men or so to speak, in particular I’d like to speak to Lileath (preferably away from Khaine) and humbly say “I’m from the future, what the heck are you thinking, don’t tell the freaking God of murder and death that he is going to be murdered and deathed, you blow up the freaking Universe! Also if you’re going to give your creation mind powers you probably should tell Kurnous not to go crazy with the desire / whole pursuit of pleasure thing… you get literally get eaten by it, check my memories I can’t make this [censored] up”

Either I get smited or the War in Heaven never takes place, Khaine doesn’t become (more of) a jerk, Lileath now knows of every event in the 40k universe, pleasure cults are not created, Eldar pantheon not eaten, the Eye of Terror isn’t created by the fall of the Eldar and no Horus Heresy…job done?

Easy, jump to middle ages, conquer the world with little effort, task my Apothecary and Techmarines with extending my lifespan dramatically a la Kor Phaeron and other not-Astartes Marines, rule the world for generations, hopefully inspire the Emperor to get a move on with his Primarch Project

We know the Dark Angels would *really* love the chance to stop Luthor and save Caliban for themselves...but that's thinking small.

Send either the Raptors or Raven Guard to counter-sabotage the (already altered) orders sent from Horus to the Space Wolves to exterminate (rather than detain) the Thousand Sons; this would in theory prevent their fall to Chaos, and allow the Heresy to be stopped earlier before it spiralled out of control.

Failing that, hijack the Pharos and send it on a course towards Terra *before* Gulliman could get his hands on it would mean more forces make it to the siege and don't get diverted by the whole Imperium Secundus nonsense.

One idea might be to take 100 iron hands loaded with tech priests (or forge masters), teleport them into Horus's battle barge some weeks before they launch their attack on terra straight into the warp-core room. Have the most techy dudes blow the warp core asap, while the others protect them (if needed, since they won't be there very long).

Two possible outcomes:

1. Horus dies in the ensuing explosion (and if you time it right you might catch a few other Primarchs there having a meeting).
2. Even if Horus gets out somehow... the battle barge, sitting in the middle of the fleet.... would take out a good chunk of the fleet and man-power and thus delay the attack long enough that maybe Russ and co. make it to terra in time to stop Big E having to teleport and meet Horus.

If its allowed, I would probably have my 100 marines disperse into 10-100 (not sure how many marines it takes) of the biggest ships spread through the fleet and detonate the warp cores...

boom!...maybe I just like to blow stuff up..... also these dudes, "could" have personal teleporters to try to get away....err....somewhere....hmm.... in the middle of the enemy fleet who are now well pissed?!...tricky

Murder Lorgar.

A hundred marines with him young and in his "I'm the weak one" state; he'd be a complex genetic stain on the floor. Then go searching for baby Erebus for bbq, and have Kor Phaeron receive the medieval treatment.

Possibly cleanse his entire homeworld. For the imperium and all.

Go to Tau planet before warp storms. Hunt all Tau.

No more Tau, one less Xeno race to deal with, resources can be used else where.

Fire very accurate, long distance, highly explosive, micro-missile at Matt Ward's house.

Could also do Crimson Fists, army everyone with Lascannons, shoot the errant missile that destroys the Chapter Monastery out of the sky. Aid in wrecking the Orks. Proceed to go on Ork-killing crusade.

May also elect to hunt Erebus and Kor Phaeron.

Assuming I can leave the galaxy, go to the origin lab of the Tyranids and burn it to the ground. Stop whatever race decided to play god before their pets ate them and a few quadrillion other planets; each filled with other sentient races no one will ever contact.
Oh, and Macragge.

Find the puddle of primordial goo from which the old ones evolved.

Shoot it full of bolts, then burn it.

Split them up, send 5 to the location of each primarch (the day after they were scattered) and bring them home ASAP. This results in the following

- primarchs are not influenced by the world they "would have" grown up on
- no clashes with each other/the emperor over ethics/culture/ideals inherited from different upbringings. importantly, Lorgar may not have possessed the need for religion and so doesn't fall to chaos
- Corruption of horus never occurs (and the emperor may never have shown favouritism for horus, due to the changes in the primarchs upbringing and Horus not being found first so getting more 1 to 1 with the emperor )
- No heresy, emperor finishes golden throne uninterrupted and imperium curbstomps

My HH knowledge isn't the best, but I'm pretty sure that solves the major events leading up to the corruption of Horus and subsequent mess the imperium falls into as a result.

Probably true... although chaos being the patient long-war-players they are may well be able to do the corrupting in another way.
The 5 Primarchs I would select are:
- Lorgar (as explained)
- Angron - so that he does not hold a grudge for his gladiator bothers / sisters being killed while he is taken away (and no butchers nails!)
- Mortarion - so that he is not some toxin-world-slave nutter
- Konrad Curze - Again to save him from becoming a physco
- Fulgrim - to teach him humility (and not be such a vain perfectionist)

I would leave Horus alone, he was fine really - it was the mortal wound and then the Davinites (and then chaos themselves) that corrupted him. It didn't help that the emps left without explaining - that probably needed to be resolved.

Considering the Eldar Pleasure cults were started by a Greater Daemon of Slaanesh, good fething luck with a Company of Marines.

Isn't this backwards? I thought the fluff was the Eldar pleasure cults were what creates slaanesh and the eye of terror. This is why Slaanesh thirst for Eldar soul stones and why the Eldar hate Slaanesh.

Yeah that was pretty much my train of thought. Another one to focus on would be perturabo (one of the primarchs who's early life resulted in him becoming merciless/brutal the first thing he did when given his legion was decimate his legion for feths sake!). The reason I suggested to return all of them is because they all have little character flaws which could have been ironed out with the emperor there to raise them. Either that or their problems would have been exacerbated, old emps has proven himself to be quite a terrible father figure

Mortarion actually wasn't bad off. Angron, Curze, and Lorgar would all need the most assistance.

Simple:

Get in the ship, the same damn ship that carries Erebus, which was on its way to Vengeful Spirit to meet Horus for the very first time.

Translate out of the time travel, board the ship, kill Erebus with bolter fire, cremate his body, and fire his remains at the nearest star in a torpedo.
That smooth-tongued SOB must not spread his dangerous "word" nor lodge culture.
It's HIS primary fault that the snowball turned into an avalanche.

Go back to the eldar in their prime. Show them the unspeakable evils that will take place if they continue down their path of conceit. If they refuse - destroy as many eldar worlds as i can in the hopes of preventing the creation of the dark god.

Best thing to do:
Take one hundred Marines from Chapters that are enemies of the Adeptus Mechanicus, travel back to DAoT, learn how to maintain STCs, use STCs to construct more STCs, when Old Night comes along, I'll have a hundred super-soldiers and who-knows-how-many Iron Men and auxilia (because, of course, we will treat the Iron Men like people, and, thus, escape the fate of their rebellion ). When end of Old Night rolls around, I'll use my non-Warp-FTL-equipped ships (source: Priests of Mars) and outsider's knowledge of the 40k-verse to show the Emperor the error of his ways, set myself up as the true Omnissiah (how much you wanna bet they had enough implants [during DAoT] to make someone absolutely godlike? Plus, I could show them how to create STC machines). Of course, I'm still a teenager, so I would become an Astartes to make myself biologically immortal, and thus able to create a new Legion with which to carve out a little pocket empire and protect a Star Cluster which will continue progressing in technology, even during DAoT, as I heavily regulate Psykers and send envoys to the Eldar to assist the Craftworlds in their escape (you can't stop millions of years' worth of gradual decline into Hedonism). By the time that the Emps tries to create the IoM, I'll be able to force him back into his previous role as a hidden shepherd (there would already be an emergent galactic human power to prove that he doesn't have to take a dominant role in human history, and, if he refuses, I'll just exterminatus Terra, even he couldn't survive exterminatus), would be able to subsume such human cultures as the Interex, Diasporex, etc. and form alliances with such alien empires as the Kinebranch, Kroot, etc. I'll move on to awaken the nobility of Necron tomb-worlds one by one; murdering all those who refuse to serve me. I will, of course, create clear lines of succession, and a multitude of councils and congresses that will hold ultimate power, and will have innumerable checks and balances to mitigate corruption. All of this will be subservient to me, of course, until I choose to step down . Once the Necrons have been made into vassals or annihilate, I would step down and let someone else be named Warboss.

Me? Personally, I'd go to T ' au when the world was first discovered, and bomb the gak out of the primitive aliens. I kind of have a love/ hate thing with the Tau, and this would mean no Eastern Fringe annoyance crusades.

Wouldn't extinction of the tau pave the way for an invasion from hive fleet naga? The only thing that saved the tau was their ability to counter the fleets insane rate of evolution by adapting their own tech in response. The imperium aren't that tech savvy = bad. Not sure if brute for would win that war.

Yes, because the Imperium of Man didn't beat Kraken and Leviathan, two larger Hive Fleets... Oh, wait, Yes it did!

Here's a dice roll.

I'll take 100 deathwatch 40k years into the future, see where we end up a maybe repopulate via cloning.

Well it depends. I feel like if the imperium had more time/warning of horus and his betrayal they could have stopped him. To that end since he has so many more Marines I would say jump back to when his betrayal was just starting and lure some orks to start a war with him. Probably after a few of his first battles where he betrays the imperium. This way he is delayed and weakened long enough for the imperium to probably crush him. The orks don't even need to do anything but be a nuisance and draw more to them.

Not to mention the varied and disparate nature of the Imperium's armed forces compared to the Tau would mean that Naga's whole schtick of adaptation would have been redundant and been ground down since they gave up overwhelming numbers for rapid evolutionary responses.

I'd go back and stop Magnus from making the warp jump/ what ever he did to bsod the webway thing the emperor was building.

And i guess kill Ahriman while we're there.

Really, the time that you time travel to depends on what kind of Galaxy you want to create. If you would like the Imperium of Man to remain dominant, but with Big E at the head, you fix the Webway, if you want humanity united, you kill Lorgar, if you want things just the way they are, only change a few things to ensure that humanity comes out of the Heresy (or Reign of Blood, it really depends on how good your grasp on 40k history is) stronger than it was before, etc. etc.

Alrighty, *checks rules*.

Got a couple options that come to mind:

1 - Head to each primarch 'homeworld' and pick up the kiddos, keep'em safe and teach'em the way of the future until pops shows up. Big family reunion years later where I sit down with Big E and inform him of everything that's due to happen because of his stupid bs.

Barring that, purge every planet. Kill everyone and everything, primarchs included, force the emperor to start from scratch and give chaos no backdoor.

2 - If you follow all that Cabal crap, change the path of a nearby meteor so it intersects with Earth pre-20th century. Erase humanity from the equation - allowing other species to evolve and dominate the galaxy.

3 - Take every Paladin from the Grey Knights, drop into the Istvaan fight and kill Fulgrim.

4 - Drop in on Phall, specifically Perturabo's ship and waste his ass.

5 - Although, I suppose the bigger picture is what's needed, so, see to it that humanity loses in some way. End up in Tau space, nurture the Tau and make sure they're the guiding force for the galaxy - establish armies throughout the galaxy capable of countering the Tyranids. Where possible, work diplomatically with the Eldar and Necrons (although that may seem silly) and other races. Kill every single Ethereal.
Note: I'm not even a Tau fanboy, I just think they've got the best shot at stopping ANYONE given enough time.

1 and 2 create a time paradox unfortunately

That's sorta what I meant though, naga would be able to feed through all of tau space (not that much, I know) and the outer trade worlds, gaining biomass before it reached the imperium (there would be no real threat to stand in it's way until it reached the imperium). If nagas main weakness is its size, what would happen if it was given the chance to grow?

I just thought that the tau would make less of a problem than yet another hive fleet knocking on the front door.

I'd take a hundred Iron Hands, post-Istvaan V, give them thunder hammers, and deploy them on Chemos before the Emperor arrives there.

Next, whip out a folding chair, grab some popcorn, and watch one hundred very pissed off Iron Hands hammer pretty-boy Fulgrim and his entire planet into oblivion.

I would stop Kirby from taking over GW. I know that's in Sol, so I guess I would time travel to outside of Sol then fly to Earth in a space ship.

Congratulations! You have stopped Kirby from taking over GW! You have now created an alternate timeline where GW is run by C.S. Goto! I hope you like multilasers...

I would take my Marines to Urk and shoot Ghazghkull in the face with 100 meltaguns. That should take a hell of a lot of pressure of the Imperium. Alternatively, teleport onto Colchis and wreck Lorgar's s***, stopping him from getting a little too close to Mr Skullthrone and preventing the Heresy.

Take every Paladin from the Grey Knights, drop into the Istvaan fight and kill Fulgrim.

If you're going to take Grey Knights, go hit Davin before Horus gets there. With no idea who or what he's facing, and hence unable to use the anathame, Temba should go down like a punk.

As a result, Horus finds the possessed governor, and the Anathame. He's not completely stupid, and when he realises that this is a setup designed to kill him, and that Erebus set him up, things should shift rather dramatically.

Travel to Fenris, with a hundred Blood Ravens, at the moment the ship full of settlers arrived.
Assume control of the ship, fire at the planet until everything is dead.
Possibly direct settlers to more reasonable world.

Millenia later, Leman Russ arrives and is not raised by wolves, either dies or is frozen in the ice, discovered by the Emperor as a corpse or baby Captain America.
No savage, superstitious idiots are recruited to be part of the VIth legion and it either has no primarch or a primarch raised by the Emperor and his attendants.

Magnus is escorted to Terra to be shown the error of his ways by a reasonable legion whose military forces include 0 dogs, dogmen or sleds.

The Thousand sons are on Terra when the news of the Heresy hits and are given dispensation by the Emperor to use their powers in a limited fashion to defend the Imperium.

Magnus can take the throne for his father, allowing the daemons to be repelled from the palace, webway gate repaired and his mistakes to be fixed.

The Horus Heresy is a resounding victory for the Imperial forces as Magnus and the Emperor's combined psychic might ensures the teleport beam is not disrupted and they arrive in Horus' throne room together with Dorn and Sanguinius.

Backed up by his very best sons, Horus is disarmed and secured in chains of silvered adamantium and the Vengeful Spirit is overrun by a vengeful Emperor and his Champion, Mage and Angel.

In the years that follow known as 'The Scouring' the Ultramarines legion is broken down into chapters to repay for the treasonous 'Imperium Secundus' of Guilleman and sent on penitent crusades to recover worlds lost to Horus armies whilst more worthy legions rebuild their numbers.

Guilleman himself is returned to the palace and 'seconded' to Dorn, the new Warmaster as a clerical aid to help keep track of the myriad wars and organisations of the new Adeptus Terra.

Keeping in mind that every single loyal Primarch initially threatens violence and shows complete disbelief to the messenger who first informs them of Horus' heresy so without proof I think any plans to warn will be completely wasted.

I would suggest dressing your 100 marines up as Word Bearers and teleporting them to the ship when Fulgrim tries to bring over Ferrus Mannus to the dark side. Have 2 shoot at both Primarchs and the other 98 shoot specifically at Fulgrim's daemon sword. If you can destroy that before he fully gives in to the daemon then his head will be cleared and he will come back to the big E's way. Both Primarchs will definitely survive and kill all 100 "Word Bearers" and turn all their rage on Lorgar and his gits, which will hopefully stop the events at Calth and even better get Erebus destroyed. Thus the Istvaan trap no longer works as Fulgrim is able to warn all loyalists, plus FM gets to keep his head and the Iron Hands are still a relevant force.
Your troops will all die but they will save their ancestors and possibly make themselves redundant anyway.

This plan is great, but hinges on every apothecary in two legions deciding not to check the geneseed of those 100 "Word Bearers" who teleported in without any ships in the area.
If the corpses were tested and the evidence suddenly pointed at :

Guilleman- Ferrus would enlist Fulgrim for an attack on Ultramar and find Lorgar already beat him to the punch for his treason. The two traitor legions would let Ferrus spend his fury on Guillemans lot and either one loyalist legion would be exhausted killing loyalists or turn to chaos in the confusion.

Dorn- Ferrus is livid that best brother could do such a thing. Ferrus arrives on Terra and requests parley with Dorn, as the news of Isstvan hits. Ferrus' legion are not in position to take part in the dropsite massacre and while Corax's leadership is significantly better, the loyalists are outnumbered far more dramatically and even fewer if any salamanders and raven guard live.
Ferrus' legion are viewed with some suspicion.

They are some valid concerns but is it implied anywhere that any apothocary other than Fabulous Bill has a schematic of all other legions geneseeds? Surely the standard check would be "Our or Not-Ours", not specific to each legion.
And the main goal is to destroy the daemon sword so Fulgrim is awoken from his spell and knows all about the treachery. So even if he works out they weren't actually WBs he sees that they were saving his soul so runs with the hatred of WB and Lorgar, who he was not the biggest fan of before.

Also if Corax was in charge of Istvaan he was more level headed so would have waited until the numbers favoured the loyalists higher, and they would all know the WBs were not actually on their side.

Wouldn't be a good choice to go back to the Legion days, 100 marines would be a drop in the bucket compared to the 50,000 and up, marines and armored support.

I'd assume that of there was no Tau, then the Imperium would already be in that part of space.

Calth. Onto Erebus' flagship. Take out the traitor and deal as much damage to the word bearers, leaving the Ultramarines at a higher strength and potentially stopping the Ruinstorm. The Ultramarines then can deploy towards Terra and potentially save the Emperor.

Head to Murder save Blood Angels, Eiloden then doesn't attempt to stroke his ego by saving them, Luna Wolves then don't follow that up, ideally it's the Blood Angels that end up heading to Interex, rather than Horus.

Your move Chaos Gods.

They chose to corrupt Sanguinius, who was like wise loved near universally by his brothers, and almost more by the Imperium at large. So the potential for maximum corruption is achieved, with both Sanguinius and Lorgar whispering in their brother's ears.

Except Sanguinius might have been more loyal. Sanguinius was never close to Lorgar or his legion, whereas Horus was close to everyone. Warrior lodges wouldn't have gained support in the IX because they wouldn't like Erebus, and certainly not him saying to defy their Primarch and Emperor. When Sanguinius was faced with the reality of his best friend and brother being the Arch-traitor, and that he codemned the BA to death so Horus could be the big baddy, instead of choosing to spite Horus and take revenge, he stood loyal, banished Daemons and then fought Horus despite knowing if would kill him.

The means of attempting to try and corrupt Sanguinius were also different. If the Chaos Gods directly would have made the effort it could have ended with him being alot less loyal.

Basically, if it works, the Imperium is doomed. If it doesn't, Oh well chaos goes back to the drawing board and their plan is delayed slightly.

Horus and Sanguinius were never going to be on the same side. Horus' corruption rested on his pride, if Sangy had been corrupted his own loyalty would lead him to doing the same as Sanguinius did, trying to save his brother. That's the impression I get from the first 3 HH books. And when Horus was corrupted, his ego meant he'd rather kill his brother than let him join, because A) He was ore powerful and a better champion of the Dark Gods B) Horus considered him a direct threat to his unchallenged command.

I would take the entire Deathwing to the moment Luther and the Lion are dueling and let them WITNESS the fething thing. Just for the kicks.

I would take them to Isstvan III and kill Abaddon. And Eidolon. Feth him.

split into 3 groups (and by extention times, I suppose):
25 marines go and back up Angron's Rebellion. By the fluff of marines, this should be more then enough.
25 marines go and kill Erebus and Kor Phaeron ASAP before the censure of the word bearers.
50 marines and I go and inform Magnus about the future and the dickery from tzeentch. From there, we visit the Big E, and explain chaos a bit, threats of the future, and the like.
