Small biography:

The Malkavians are insane. Their madness dwells in their blood and is passed from sire to childe generation after generation. Of course, madness is a subjective thing. Those afflicted with it might regard it as a gift more so than a malady. The forms that the madness takes run the gamut of known archetypes - from the loony prankster to the tripped out conspiracy nut to the stoic but sadistic psychopath who might seem outwardly normal and not reveal the extent to which insanity rages within him.
