The clan known as the Troiks, residing on the planet of At Achrann, were under the command of General Strix. This clan possessed a military force known as the Troik Army. They were engaged in conflict against the Hattans. Hayna, Strix's daughter, aspired to succeed her father as the leader of the Troiks. The Hattans had stolen a group of horned eopies belonging to the Troiks. A deal was struck by Jod Na Nawood with the Hattan, where the Hattan received some dataries from a couple of Wim's, and in return, the complete herd was returned. Following this, Nawood and SM-33 brought the animals back to the Troiks.
The Troiks were initially featured in the Star Wars: Skeleton Crew episode titled "Can't Say I Remember No At Attin," which was the fourth episode of the series.
