During the time of the Separatist Crisis, Empatojayos Brand, Bultar Swan and Chellemi Chuovvick, who were Jedi Knights, were dispatched to the Sepan sector with a task: to broker a peace agreement for the ongoing Sepan Civil War.
While the Jedi were trying to negotiate, the decades-spanning civil war was put on hold for about a month. Nevertheless, after they went back to Coruscant, the fighting started anew, this time centered around the question of whether Sepan should secede from the Galactic Republic.
