Memory:Ar'Xanth

The wraith is an undead, that often manifests itself as a cloud. They are vaporous and chilly to the touch. Often two glowing red eyes can be seen inside the cloud, staring at their unfortunate victim. The wraith thrives on the energy of the living. A person killed by a wraith often, but not always, becomes a wraith himself. An almost immaterial apparition, it looks like a dark pillar of smoke, striking vague reminiscences of human shapes. It hungers for the blood of the living, and you look tasty.
