Sajen was a Suliban male imprisoned at Tandaran Detention Complex 26. He was a friend of Danik. Sajen kept a journal of his time at the detention complex. When Starfleet officers Jonathan Archer and Travis Mayweather were imprisoned there in January of 2152, Sajen and Mayweather were initially wary of one another; Mayweather because of preconceptions of the Suliban after run-ins with the Suliban Cabal, and Sajen because of the Human's physical resemblance to Tandarans.
