Ok there have been many theorys about the warhammer world and the 40k universe, I have only just started to think of this so bear with me if it isn't clear.
The old ones first created the 40k universe but this was comprimised by the chaos gods and their presence in the warp, they flee into the webway to create a new world away from the chaos gods influence, they create the slann in their own image or to reproduce after their war with the c'tan, but chaos manages to get to this new world so they try to close the portal to stop them but they fail in a way and chaos still manages to corrupt the new world they have created, so then they leave this world and creae another world hopping to stop the chaos gods.
I hope this makes sense to you people but for a summery, chaos is corrupting the old ones work so they create a new world to stop chaos from corrupting everything but find they have corrupted this as well so the old ones move to create another world leaving it to it's fate like the 40k universe.
