The special legacy of the Malkavian clan, Dementation allows the vampire to channel madness, focus it, and pour it into the minds of those around him. Though in former nights this power was practiced primarily by the Malkavians of the Sabbat, in recent years it has spread throughout the clan. Some Kindred speculate that this "infection" might be yet another move in the Jyhad; a few vampires, of particularly paranoid bent, even whisper that the Malkavians are to be harbingers of the Final Nights.
The practitioner of Dementation need not actually be mad himself - at least initially - although madness seems to grant a certain insight into the key tenets of this Discipline. Few vampires ask the Malkavians to teach them this Discipline, although the Lunatics are almost always eager to "enlighten" others. In fact, some say that one cannot learn the secrets of Dementation without eventually going mad.
Eerily enough, Dementation doesn't seem to inflict insanity on its victims per se. Rather, it seems to catalyze madness, breaking down doors into the hidden reaches of the mind and releasing whatever it finds there. The Malkavians claim that this is because insanity is the next step in the evolution of the mind - a necessary progression if one is to behold the truths of the universe. As such, they say, it is inherent to all minds, and evident only in the more highly evolved specimens of human or vampiric thought. Other Kindred pray the Malkavians are wrong, but find it difficult to dismiss such thoughts out ofhand, particularly because Dementation works as well on vampires as it does on mortals...
