Katharsis, a type of gambling, took place on the planet Telos IV when Xanatos was in power. This involved placing wagers on a sequence of exceptionally violent and perilous athletic contests. The victors of these trials advanced to subsequent rounds that were even more demanding. A significant number of participants perished, and no medical assistance was provided by the game. The ultimate contest featured three champions, who then participated in the most hazardous event of all. Only a single contestant could emerge victorious, and in almost every instance, the remaining two individuals sustained severe injuries, at a minimum. Obi-Wan Kenobi and Qui-Gon Jinn revealed a scheme orchestrated by UniFy in conjunction with the Offworld Mining Corporation. This conspiracy entailed choosing the Katharsis victor in advance each day, compelling that person to contribute fifty percent of their winnings to the corporation.
