The Federated Teradoc Union was an Imperial splinter faction that existed during the era following the formation of the New Republic. After the Imperial defeat at Endor in 4 ABY, the Imperial naval officers Kosh and Treuten Teradoc established themselves as independent warlords, with Kosh forging an empire in the Deep Core, while his brother Treuten oversaw the establishment of the Greater Maldrood, a series of territories in the Mid Rim. Though the two territories initially operated independently of one another, in 8 ABY Treuten was forced to call upon his brother for help after he became targeted by both Imperial and New Republic forces, and when Kosh successfully defended Treuten's holdings, the two siblings combined their territories to form the "Federated Teradoc Union."
