Vampiric (trait)
Almost entirely sustained by dark Magic, this character's body has long since passed any state in which it can sustain a human life. Without the magic they would die near immediately, and most Magi would rather go full of body and mind instead of allow themselves to reach such a state. While sustaining ones life through Magic is seen as acceptable in many societies, doing it so often and for so long that one reaches such a state is not, especially due the increasing and disturbing costs of the rituals to perform it over decades.
