"There are many varieties of undead, Leo. They vary in intelligence and don't always have to be inhabiting a physical body." Trahearne was starting to frown a little, also no longer paying even a scant bit of attention to the bibiru trying to eat his leaves.

He gave Leo a level look, keeping his tone carefully even as he spoke up again. "I spent most of my life studying the undead, among other things. I wouldn't have become a necromancer without such a need to understand the workings of death. Later on, I directed an army against the Risen. I read the reports every time my troops died, every time a unit fell at the hands of undead that had been their friends and allies moments before."

Trahearne paused momentarily, sighing before adding, "My point is that I know what terrible things they're capable of. A type of undead creature that can easily move among the living, and feeds on them, is one of the most chilling thing I can imagine. And now you come to me saying that I shouldn't worry because he's found some reason to not want to hurt you?"
