Iliana Hilts (née Merko) was a Force-sensitive female Human who was a member of the Lost Tribe of Sith, the descendants of Human Sith who had become stranded on the Wild Space planet of Kesh during the Great Hyperspace War. Iliana became the leader of the Sisters of Seelah, which was a splinter cult that revered the memory of Seelah Korsin, the estranged wife of the Tribe's founder Yaru Korsin. In 3000 BBY, Iliana attempted to manipulate Caretaker Varner Hilts to give her and her faction political on Testament Day. This attempt failed after Hilts tricked her into believing that the holocron of Yaru Korsin, which contained Korsin's Testimony, would only activate on Testament Day.
