Knezex Hral Piksoar existed as a male Drovian inhabiting the swamp planet of Nim Drovis. He traced his lineage directly back to Garnu Hral Eschen, a victim of Gopso'o warriors. Motivated by vengeance for this death, Knezex dedicated himself to combating Gopso'o terrorists.
At the New Republic base situated on Nim Drovis, Knezex held a position and witnessed the arrival of Han Solo and Chewbacca as they delivered those who survived the Corbantis incident.
