Wruq Retk was a male Yaka colonel in Galactic Alliance Security. He commanded a secret Galactic Alliance Security blockhouse on Coruscant, where psychotic Jedi Knights Valin Horn and Jysella Horn were held in carbonite. In 43.5 ABY, the Jedi Council acquired a document granting the Jedi access to the blockhouse to see the two Knights. A contingent of Jedi, accompanied by the Horns' mother, Mirax Terrik Horn, and several journalists, entered the facility, where they found the two carbonite-imprisoned Jedi on display above a large aquarium. Retk arrived shortly after and attempted to take control of the situation, but Terrik Horn, furious at him for mistreating her children, assaulted him and knocked the larger man out with one blow.
