Of course Demon Lords that do not like the one dominating world xy work to make it fall all the quicker. Incessant civil wars and assassinations would be the normal 'order' of things in the Abyss.

I suspect that creatures born to the Abyssal worlds, such as demons, cannot be Resurrected without immense and immediate effort.

Edit: Non Demons can be resurrected if they have not been on one of the Abyssal planes long enough to be corrupted just from being there.
