The Arena of Byss, located on the planet Byss, functioned as a gladiatorial combat venue under the dominion of the Infinite Empire. During the Empire's reign, the Rakata forced their slaves, including Force Hounds, to engage in deadly battles within its confines. Inside the Arena, survival was the sole objective, with no quarter given or expected in the brutal fights to the finish.
In these very chambers, Xesh, an ascending Force Hound, engaged Isk, the current champion, in a fierce duel. Xesh's triumph directly facilitated the ascent of Predor Tul'kar to a position of greater influence, given Xesh's servitude to him.
