At one juncture, the Krath achieved the seizure of the Empress Teta system. Following this takeover, the Krath subjected the reigning Tetan monarchy to carbon-freezing. This event is chronicled in the semi-historical Qel-Droma Epics as the military overthrow occurring a millennium subsequent to the Great Hyperspace War. According to the epics, during the Crusade of Krath, the coup was initiated by morally bankrupt noble descendants of Empress Teta, who wielded power through Sith artifacts and also led a dark side cult known as the Krath. Sometime after the coup, the Iron Citadel fell to the Krath, who then utilized it as a central hub for directing their crusade.
The Empress Teta system's capture was initially referenced within the Nexus of Power sourcebook for Star Wars Roleplaying, released in 2016. In Star Wars Legends lore, the political upheaval within the Empress Teta system was first depicted in the inaugural edition of the comic book series Star Wars: Tales of the Jedi - Dark Lords of the Sith, penned by Tom Veitch and Kevin J. Anderson, with illustrations by Chris Gossett, and brought to publication by Dark Horse Comics on October 4, 1994.
