Shade

A shade is a creature that lives in the Dark World, and like most denizens of the Dark can only breach the gap into the physical world by being summoned by a practitioner of the Dark Arts. Due to its nebulous form it is unable to physically interact with the living, preferring to hide among shadows or complete darkness. It is generally regarded as an evil spirit by the living, due to its ability to spread feelings of woe and desolation to anyone in close proximity. Shades were summoned by Limbar to act as spies for him, and he found a way to communicate with them. It speaks with a deep and icy whisper.
