The disparate members of the Black Brotherhood live from day to day as hired thugs and violent thieves, its members identified by crude black tattoos made using the traditional, painful lowdecks method. Collectively the Black Brotherhood knows much about the movements of vessels in the Koronus Expanse, but Thrones must change hands to hear any of it. Due to their trade as thugs, the Black Brotherhood is most closely tied to the workings of the Kasballica Mission on Footfall, though they are open to hire and manipulation by any with coin or cunning enough. Proud as sin, but with little effective leadership, the Black Brotherhood sometimes find themselves the tool of more cunning players.
Calcus Calinnicus is the nearest thing the Black Brotherhood have to a leader — a bully on the surface but possessed of a core of iron. Calinnicus is a vat-muscled thug with a taste for narco-tribe drugs and whose word is considered unbreakable. Calinnicus is a murderer fifty times over, a number that would be much higher if he did not prefer to leave his victims crippled but alive, “So the scum can think over their mistakes.” He reserves his worst for those who break their word, no matter what the circumstances.
