Zinska was a male human prisoner at the Imperial facility situated on Narkina 5, where he held the position of floor manager for the night shift unit in Level 5, Room 2. In the bridge-corridors of the facility, Zinska often crossed paths with Kino Loy, the floor manager overseeing the day shift on Level 5, during shift transitions. These encounters provided them with a chance to exchange brief updates on the facility's activities. Initially, Loy dismissed rumors concerning the deaths of 100 prisoners on Level 2 as false, but Zinska's confirmation changed his mind. As the uprising against the prison's staff unfolded, Zinska heard Kino Loy's call to arms, broadcasted across the facility from a commandeered comms station. Following this, he guided the men under his supervision to unite with Loy and the prisoner Cassian Andor in their determined fight for liberation.
