As far as your mention regarding death and spirits the method of reanimation is barred only to extremely powerful beings such as gods correct? Is there a concrete understanding to which entities exist in this realm that fit something close to that description or is that flexible? I'm happy to discuss possible alterations to the background I'm designing for her if you have changes that would help make her better suit your setting. I'll have something more concrete to present when I finish her background. I'm just doing my student's background first before I get to her CS.

No, not really. There is no evidence that the Twin Goddesses have actually exercised necromancy. It is only believed that they could do it since it's super, super hard to cast it.

Also, while there's extensive speculation and pop culture about undead, zombies and skeletons, no such being are ever encountered in the world.
