What does it even mean for something to be consumed by the Void? Is it destruction or is it perhaps transformation? Is Karesh perhaps floating in the void as something else, devoid of the constraints of the natural world?
This is the issue with the Void. The original description makes one thing it is simply oblivion. It's aspect would be hunger. Yet the more we find about it, the more it seems like the Void is about breaking boundaries, about unrestrained freedom (Even from sanity or form). I would say that makes it inherently chaotic. If Fel is Chaotic Evil, Void seems to be Chaotic Neutral. Its evil is incidental because it is beyond morality.
