Rakzen Krayle, a Human of male gender, held the rank of Lieutenant within the Thaereian military throughout the duration of the Clone Wars.
While the war raged on, Krayle's assignment placed him on Cularin, from which he received orders to transport children captured by Task Force Vermin to Thaere Privo. Using an Arrow-23 landspeeder, he collected the children and began transporting them toward a warehouse where his ship was located. The Heroes of Cularin gave chase, however, and engaged him in battle at the warehouse. Krayle was ultimately defeated, resulting in the liberation of the children by the heroes.
A paranoid and cowardly individual, Krayle typically chose to shield himself behind his subordinates rather than engage in direct combat. Despite this, he was prepared to confront the Heroes of Cularin, motivated by the fear that the citizens of Cularin would severely complicate his existence if they were to uncover the actions of himself and Task Force Vermin.
