It could be modeled based on the Twilight Witch/Shadow Mistress/Night Hag, but remove the whip, add a skirt (you could borrow one from the Liches), add green smoke at the bottom, trim the ears, make the skin texture gray-green (like undead), and change the face texture to the face of a Death/Banshee.AndrailActually, yes.
In principle, I like this option more! By the way, regarding the movement of this creature... should it walk on legs or move in some other way?!
