T'ieks's Fortress was the home to the Zion Alliance community. It was a space base twice the size of an average moon. Although T'liek's Fortress was not a real planet, it had an orbit and remained still and immobile in the Yathanus system. It was named after the Zion Alliances' commander-in-chief Graal Bonkus's deceased friend, T'liek Notus.
