Karbacca was devastated to hear that his master, Atok Mar, had been killed by Sith forces in 3,653 BBY but was even more horrified when, later in that year, the Sith Empire led by Darth Malgus sacked Coruscant and destroyed the Jedi Temple. Even worse, his apprentice, Kent Star, was among the dead from the assault. Karbacca, along with the rest of the Jedi, returned to Tython, where he stayed for just under fifteen years until the Jedi and Republic forces were successful in destroying the Sith Empire.
