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 20 feet (six meters), and their bodies were smooth and hairless.
