Je'har
From Wookieepedia, the Star Wars wiki.
The Je'har were the tyrannical upper caste rulers of the planet Almania, based in the Great Dome of the Je'har. They originally were supporters of the Rebel Alliance, but underwent a shift to a dictatorial, mass-murdering regime during the Thrawn campaign.
During a raid against the moon Pydyr, the Je'har killed the parents of a young man named Dolph. After seeing his parents' corpses, Dolph turned to the dark side and became Kueller. He then returned to Almania and slaughtered the Je'har regime.
