Necromancy

Users can control the dead, or sometimes their Ghosts. They are able to animate corpses and dead beings, making them move and react. These bodies are usually under the users’ control. However, some users may be able to create sentient or semi-sentient undead, or even completely Resurrect a person.

Some users can also telepathically communicate with cells, bacteria, and dead/disintegrating tissue of corpses, speak to dead spirits either using their physical remains or on the astral plane, and briefly summon images of deceased people from the minds of others.

Advance users can cheat death one way or another, whether by becoming some form of undead creature or by bypassing their own ability to die.
