Dakarai Blirr, sibling to Sadiki Blirr and a male Human, held the position of operations officer and was the architect behind the Cog Hive Seven prison. Under the guise of Zero, a male Twi'lek, he was secretly in the employ of Iram Radique, a clandestine arms dealer whose operations were based within the confines of the prison. Blirr, in his Zero persona, engaged with the prisoners while discreetly importing components for Radique. Eventually, his life was ended by Coyle, an inmate, following Radique's uncovering of Blirr's real persona.
