Klarzen was a security officer for the Fifth Axis. When the Axis took over the Braxiatel Collection, Klarzen was nominally in charge until Mushtaq Anson arrived.
Klarzen interrogated Irving Braxiatel, hoping to find the location of the Oracle of the Lost. Braxiatel fooled Klarzen into thinking the Oracle was a fake. (PROSE: Careless Talk)
