An Imperial base, under the control of Darth Krayt's Galactic Empire, was situated on the planet of Yinchorr. Throughout the duration of the Second Imperial Civil War, this location functioned as the central command for numerous Imperial military formations, notably the 407th Stormtrooper Division.
This base was comprised of a number of squat, dome-shaped buildings positioned on the planetary surface. The establishment of this HQ occurred in 130 ABY, and it operated as the division's central hub for a period exceeding seven years. Anson Trask, after becoming a member of Joker Squad, was transported via shuttle to the Yinchorr headquarters; this occurred not long before the squad was deployed to take part in the Battle of Borosk.
