The black/dark pools in the abyss, what is known about them really? Were they made by protodemons, is it the mother of monsters after birth or some such, or did the abyss just decide herein like prisons better than pandemonium. It's also weird that I would consider prisons lawful, which seems at odds with the chaotic nature of demons, since freedom is what I consider a hallmark of chaos. That line of thought led me to think more of protodemons than tan'ari.

When you have a moment.
