Vampire the Masquerade

Assamites in the Sabbat are much like their counterparts outside the sect,

 sharing the same basic spiritual beliefs and appearance.

 However, the Assamites of the Sabbat are free from the curse of the Tremere,

 so the blood of other kindred is not poisonous to them. For this reason,

 the Assamites of the Sabbat may be considered members of a separate bloodline. 

In actuallity, the Sabbat bloodline is the Assamite original. Since the curse affected

 the founder of the clan, however, the Antitribu, not the other Assamites,

 are considered the "subspecies." Most Assamites Antitribu are either

 paladins or members of the Black Hand. The Assamite Antitribu are the

 assassins of the Sabbat. However, they do not ask for the blood from the

 leaders of the sect. Instead, they ritually slay the eldest of their own

 clan every 100 years through a special diablerie ceremony.

 This elder has some of the blood of the Lasombra founder, 

a third generation vampire, running through his veins.

 The elder exists for a century as the closest Assamite Antitribu to Caine himself,

 ruling under the title Hulul. At the end of the 100 year reign, the next in line

 drinks the precious vitae from the previous ruler, and so it passes on throughout history.
