During the Galactic Empire's peak, a raid occurred on the planet Kar'a'katok. Major Stafuv Rahz commanded Imperial troops in an invasion of the once-isolated planet, where they assaulted the native Shimholt people. In the midst of this conflict, the Empire seized Suprema Ampotem Za, transporting him away from Kar'a'katok. Despite his subsequent escape and return, Za faced ostracization for violating their age-old policy of seclusion. Because Za permitted his capture and removal from the planet, he was banished from Kar'a'katok.
