Malkavian

Even other Damned fear the Malkavian. The cursed blood of their clan has polluted their minds, with the result that every last Malkavian across the world is incurably insane. What's worse, a Malkavian's madness can take nearly any form, from overpowering homicidal tendencies to near-catatonia. In many cases, there's no way to tell a Malkavian apart from the "sane" members of other clans. Those few whose psychoses are immediately obvious are among the most terrifying vampires to stalk the streets.

For as long as even the eldest Cainites can remember, the Malkavian have always stirred Kindred with their passage. Although the clan has instigated no great wars nor toppled mortal governments (at least, to the best of their fellow vampires' knowledge), the very presence of a Malkavian works a subtle change on a city. Chaos nips at the Lunatics' heels, and those who associate with even the most well-meaning Malkavian often find their lives or unlives altered by the Cainite's madness.

Recently, the Malkavian executed their grandest "prank" of all. None can say whether it was worked in a great Malkavian Parliament held somewhere in an isolated European village, or on a bleak and forgotten moor somewhere far from the cites. A few stories speak of an epidemic of contagious dementia exploding among those of Malkav's blood. Whatever the cause, Malkavians across the world have begun displaying a new, dangerous edge to their madness, accompanied by bizarre events in Kindred cites around the world. A longstanding Malkavian conceit holds the Jyhad to be a joke instigated by the founder of the clan; some Kindred wonder if, in fact, Malkavians have played the joke on them all along.

None can say what exactly makes the Lunatics so dangerous. Certainly, their madness often frees then them from fear of pain or Final death. More than a few demonstrate horrifying murderous urges or a complete lack of emotion, including compassion. But most convincingly, the Malkavian are free from the confines of rationality and may do whatever they like - and this freedom is coupled with an uncanny insight, a strange wisdom that cannot be perceived by the sane. The Malkavian posses a dark intellect that is often - and increasingly - set to frightening purposes.

Nickname: Lunitics

Sect: The Malkavian as a clan have an ….understanding…with the Camarilla. They also populate the Sabbat in lesser numbers, where they frighten even their packmates with their psychotic displays. But when it all comes down to it, their true loyalties likely transcend sects. When Gehenna arrives, nobody can say for sure where the Malkavian will stand.

Appearance: Malkavians run the gamut from terrifyingly psychotic to convincingly ordinary in every way — sometimes both at once. Just like serial killers, they could be anyone — the scruffy bum talking to himself, the pleasant but quiet neighbor, the borderline-suicidal musician. These vampires are capable of great subtlety, and rarely show anyone a face other than the one they want people to see.

Haven: The Lunatics by and large take whatever shelter they like, although more than a few find aging hospitals and poorly funded asylums to their tastes. Many seem to enjoy the company of desperate mortals, and prefer slums and institutions to more secluded havens.
