Aleksandar Borislav, known to his peers as Alek, was an Assassin and member of the Balkan Brotherhood, a short-lived organization of Assassins drawn from various European Brotherhoods that was disbanded shortly after World War I. Known for his difficulty with putting aside his personal beliefs when it came to serving the goals of the Brotherhood, Borislav eventually went rogue to pursue his own vendettas, only to meet his end at the hands of those he had once called comrades.
