Asteroid headquarters of the Klingon military, infiltrated by Sisko's team in disguise to expose a Changeling impostor in 2372.
Ty'Gokor was an asteroid in Klingon territory that housed the headquarters of the Klingon military, including the Hall of Warriors, where the honour of the Order of the Bat'leth was bestowed on distinguished warriors.
In Apocalypse Rising, Sisko, Odo, O'Brien and Worf, surgically disguised as Klingons, were carried to Ty'Gokor aboard Gul Dukat's captured Bird-of-Prey to expose a Changeling believed to be impersonating Gowron. Captured and then freed by General Martok, they returned to the Hall of Warriors, where Odo realised that the impostor was in fact Martok himself.
