In the Forgotten Realms setting of Dungeons and Dragons, a zin-carla, or "spirit-wraith", is a drow spell of raising and restoring a corpse and imbuing it with part of its former skills and personality, and then compelling it to perform some action. It is Lolth's ultimate blessing to a matron mother; 'zin-carla' is only granted when the result will give Lolth some kind of benefit--entertainment from watching chaos, or personal satisfaction at the destruction of the irreverent. No zin-carla had ever failed in its mission, save one.
