I'm not a big fan of Demonbane-verse but I found this:
Proof creation is just Azathoth's dream, and not even Azathoth can destroy Demonbane:
Everything is a foam on the waves
Creation is all but a fleeting dream, dreamt by the blind idiot god who is King-of-All as he dozes on the edge of waking
When he wakes, it will end
It will simply vanish, and there will be no one to know or remember it
Or perhaps it simply will have never existed at all
So is the world really nothing more than a fantasy?
But even the god who dreams at the center of the world, the god who created all things, can never, ever destroy it (Demonbane)
