Specter

Spectres are undead, incorporeal creature that resembles a ghost, with a hatred for all living things. Spectres drain the life energy from living creatures, turning them into new spectres upon death. They are powerless in natural sunlight to the point of fleeing from it. A spectre appears as a humanoid, with a mostly transparent and faintly luminous form; it look much as it did in life, and can be recognized by someone who knows what the person looked like.

Spectres are always lawful evil.
