It is interesting, how the 40k lore treats the different factions victory on the existence of the Warp.

If humans and elves win, the chaos will grow. But what about other factions? Tau are way too braindead to be angry/horny. Therefore, the chaos would die. Fucking commies.

Do we even know what will happen if Tyranids aren't stopped? The single mind seems to somehow be worse then the current chaos already.

Orgs are just happy to kill, so they are ok no matter where they go. They would most likely create a different gods, but the current ones would have no chance.

Necrons are soulless already, so they would leave the warp blank.

Did I get this part of the lore right?
