Nightwalker

A nightwalker was a type of nightshade, a sentient undead monster from the Plane of Shadow. It was unnatural and malicious, and it took delight in the corruption and suffering of others. It was a creature of both death and shadows and had enormous powers over darkness.

Description
Nightwalkers were the shades of extremely strong-willed and evil mortals whose ancient and unyielding will and malice allowed them to hold their corporeal shape. A nightwalker's body looked as if it was made of shadow-stuff, with a vaguely humanoid form. They were about the size of a house, but were usually no taller than, and their bodies were smooth and hairless.

Abilities
Nightwalkers were capable of transforming humans they killed into bodaks through use of an arcane ritual that warped the void energies of the Shadowfell. This ritual would not work on any other plane.
