Cailshh, whose gender was a mystery, served as a cunning and erratic Ubese mercenary contracted by Lik Ankkit on the planet Qiilura. Ghez Hokan, however, suspected Cailshh was male. Hokan instructed Cailshh to locate the Republic operatives. Cailshh and the team he or she led burned down all the farms they encountered, a method that did not sit well with Hokan. As retribution and as an example to the remaining crew, Hokan used Kast Fulier's lightsaber to execute Cailshh via beheading, subsequently commanding Mukit, another Ubese, to ensure a proper Ubese burial.
