Following the Battle of Endor, the Imperial Grand Moff Lozen Tolruck maintained a hidden island fortress on the planet Kashyyyk. His fortress was fortified by wroshyr wood and contained a control module which programmed and controlled the inhibitor chips that had been implanted into the planet's Wookiee population. The island fortress was located at a great distance from Camp Sardo. The fortress had several Wookiee slaves and droids and was guarded by several forest troopers. In 5 ABY, the former Imperial loyalty officer–turned–New Republic operative Sinjir Rath Velus visited the fortress to rescue his friend Jom Barell and to disable Tolruck's control module. During the liberation of Kashyyyk, the Wookiee slaves rose up in revolt and killed Tolruck and his men.
