[@ERode] i was thinking a Draugr, which is a type of sentient undead in Norse lore, there big thing was that the where spirits that wanted to seek revenge in their un life enough that they manged to get back in there bodies, though the body was basically a undead husk of its old self, i am flexible with how you want to set it up to be fair and have a reasonable backstory, i am thinking a witch as trying to raise an undead army in secret back when she tried to bring make a powerful undead of a long forgotten hero she brought back his soul and placed it in his rotten body, she escapes just leave it behind in anger of being forced back into life, he remembers little of either his old life or of the after life other then his name, how to fight, and that in death he was happier then in life, for the record i like to change two things about Draugr, one he can be outside out day time and two he would be as killable as a normal zombie ie, fire or crushing his head kills him and anything that heals a living thing hurts him, though for the lols, sort of that he can reattach any cut off body part with the aid of magic such as any from of magic that would be lethal to living things heals him
