two things: first, since magic evil creatures are kinda common, you could think some special details (Maybe they contain some dead's memory or thoughts), or this will be too cliche; and second, what kind of main characters do you want? Do you want a normal hobbit as main or some undead matrix?
The magic creatures are actually closer to mindless summons than anything else. They're kind of a by product of magic spells. I don't want to risk "humanizing" them too much by giving them memories or anything. The world I've prepared also has a very rich religious structure, so there is a religious reason for them to exist as they are.
As for main characters, I have three planned. Liz and Mist are human, and Vyre is an Eyylik. I'm not sure what you mean by "some undead matrix."
