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.

Unfortunately, Mars is within the Sol system

Face-palm, I subconsciously took that as Terra only..... derp.

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.

*reads rules*
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.

By this way slaanesh may never exist?

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

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.

Oh.....and I would go back in time to the point just before Chaos raids the old world, destroy them so they don't destroy the old world, and prevent AOS from ever happening....


Just saying....

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.
