Clan Information:
The Blood Brothers were a rare Kindred bloodline of the Sabbat, created by a group of Tremere antitribu and Tzimisce kolduns.
Designed to function as perfect combat units, Blood Brothers possessed a sort of shared consciousness, working exclusively with the "circle" of Blood Brothers with whom they share their "hive mind". The members of a circle would often be fleshcrafted by Tzimisce to appear identical, an outward reflection of their lack of individuality.
The Brothers were a relatively modern bloodline, but even so their numbers dwindled in the Final Nights as they were mostly unable to grant the Embrace (a limitation placed on them intentionally). With the loss of the Tremere antitribu, only a handful of Tzimisce knew the secrets of their creation, and it seemed likely they would die out before Gehenna comes.
One circle of Blood Brothers (Las Hermanas Hambrientas, "The Hungry Sisters") had learned to Embrace in a process of repeated vitae exchange that lasted days. Only 1 in 10 Embraces was successful, but their hunger to reproduce continued to grow with their hunger for blood.
An alternative origin for the bloodline is suggested. A member of the Blessed Choir circle claims to have found the original creation ritual for the Blood Brothers, as penned by a Vicissitude-wielding Toreador antitribu. Another section describes a rumour where a Ventrue is transformed into a Blood Brother, implying Kindred can be converted to the bloodline as well as mortals.
