I have pondered about the affect of Daemons on the Tyranids. Are the Psychic Tyranids affected and could they open a Warp rift for Daemons to manifest themselves through?

And is there a way for Daemons to last in our realm for long periods of time? For example a World gets sucked into the Warp comes out Infested the populus mad and mutated or would they all just be slaughtered?

It's a controversial point.

While all psychic powers supposedly use the warp for their power, Tyranids use the power of the Hive Mind. There's no mention in current fluff of Tyranids suffering from daemonic attack or possession from using their psychic powers, but rather just burning out their brain from overuse.

However, the Shadow in the Warp, which is the psychic 'noise' of every Tyranid in the area, sits in the warp, so their psychic energy does interact with the warp. The Shadow in the Warp drowns out all warp entities in its vicinity, so it's likely they do use the Warp, but since the Shadow is diverting non-Tyranid all signals away from the users, there's nothing there to make use of any warp rifts created.

However, there is fluff concerning Tyranids invading a daemon world, and the Imperium exterminating the planet, but those daemons were already in the material plane.

Until GW expand on it though, there's no actual fluff examples of it happening.

Thats Interesting.
I do wonder how they Interact with the Warp.
So effectively if I've read your post correctly they gain their supposed Psychic power from the electric impulses from their Synapses?

Well, that's how all psychic pwers work. Those impulses just actually interact with the warp.

The way I think of it is, since the Shadow in the Warp blocks out all other signals, it essentialy creates a 'clean' warp, like it was before Chaos manifested. So there's nothing bad there, only power to tap into.

The fluff concerning daemons and Tyranids fighitng on a daemon world would likely be possible due to two extremely powerful warp prescences clashing, allowing both sides to make use of the warp. Daemonic incursions happen where the warp is particularly instable, so it would make sense that the Shadow would have trouble smothering it, allowing the incursion to continue and the Tyranids to tap into the clean part.

But that's just me trying to make sense of fairly contradictory fluff.

Well IICRC the Tyranids have no Origin and.it was speculated they came from another Dimension that they've smoked in their ceaseless way with Biomatter.

They could be tapping into the energies in the other dimension. I understand that Synapses are the cause of Psychic powers because It's the impulse for any action. But Psychic Tyranids are not the smallest creatures and I was speculating whether the electric energy used between Synapses was enough to fire concentrated beams of it.

Because Psychic Death screams are effectively a expulsion of your trapped thoughts and memories perhaps the Synapses are the cause im their case Instead of the Warp.

All very Interesting though, but almost to much Speculation and not enough Facts.

The problem with that theory is there's no fluff basis behind there being another dimension. It's the material world, and the warp.

And yeah, it's all speculation, because that's how GW wants it. The Tyranids are meant to be a completely alien threat. Explaining their origins takes away from that. Even when they mentioned in the rulebook that they'd devoured a dozen galaxies before ours, it took away from that air of mystery.

It's simply that the Hive Mind is the most powerful warp entity there is. More powerful than the so called "gods" and so has nothing to fear from them.

Or is, itself, a Chaos God so utterly alien to the weird but, to the human mind, at least understandable Great Four, that it seems to work in an entirely alien way.

Or it's a here-to-fore-unknown aspect of Tzeentch.

Orks tap the power of the WAAAAGH for psychic powers rather than the warp as I recall IIRC. It's not really an easy thing to reconcile, but I tend to think of it as a form of highly specialized sorcery. They're tapping their "Gods" or God analogues (For the Tyranids the Hive Mind/Shadow in the Warp is basically a godlike entity, and for the Orks WAAAGH power and Gork and Mork are closely intertwined as I recall it.) Basically both races are tapping the warp indirectly through a powerful filter to puriify the warp and keep out undesirable elements.

The Shadow in the Warp basically drowns out the presense of lesser warp entities while the hive mind itself is powerful enough to keep the Gods themselves away.

Gork and Mork are the same way, too strong for the other gods to bother.

Unless they need a good smashing offcourse.

Not entirely. There is fluff of Tyranids fighting daemons on Daemonworlds. There's even an awesome picture in the daemons codex of a Bloodthirster and Carnifex facing off.

Well, yeah they can fight. but you won't ever have a daemon posessing a nid for example.

This is NO LONGER the case anymore. There's more than just the warp.

C'tan are trapped in trans-dimensional prisons, and the Necron Deathmarks hide in other demensions till their prey arrive.

I also believe i've read something mentioning deamons runnign away in terror from the "shadow in the warp" while in the warp itself?

And there's fluff and art supporting daemons and Tyranids fighting, and both using their psychic powers.

The truth is: nobody knows.
Since Hive Mind is unknown being, we only know that he is leading the Tyranids in great psychic link.
And as for the Warp we only know that he is creating shadow across the Warp, witch may indicate some natural shield against it.
But as I said, nobody knows.

I always thought that tyranids affect the warp just like all other living creatures, it was just that the shadow of the warp was an area of order within the normal disorder of chaos.
Basically, the hive mind unifies all the tyranids emotions and thoughts and feelings that there is none of the usual chaos of the warp around it.

That said though, demons and tyranids both utilize their psychic powers based on the warp, not the discord nature of chaos. So despite there being a shadow in the warp both should be able to use their abilities. However, I can see the overpowering uniformity of the hive mind drowning out most attempts to utilize that power.
