Death knight

A death knight is a mighty undead warrior, created by gods of death, evil deities, demon lords or other malevolent forces. These horrible champions of evil are most commonly raised from the ranks of blackguards, fighters, rangers and barbarians, but a paladin who falls from grace near the moment of death may also become a death knight.

Physical characteristics
A death knight's physical form is that of its decayed body, with a blackened skull, patches of rotting flesh and two pinpoints of eerie light in the eye sockets. Its voice is chilling, seeming to echo from deep within. Once powerful people in life, death knights often prefer to wear expensive or magic clothing and armor, along with flowing capes to mark them as figures of importance.

Society
Though death knights rarely worked with their own kind, they often had a variety of undead servants, such as skeleton warriors, liches and banshees. They often rode nightmares into battle.

Abilities
Death knights have an aura of fear that will route weaker enemies. They can channel powerful negative energy with a touch and project explosions of fire and unholy energy.
