A mining hangar, situated within the planet Sullust's capital city of Pinyumb, functioned as the secret base for the Sullustan resistance. This group was a Rebel Alliance cell operating from within the city. Following the successful rescue of First Sergeant Hazram Namir from the Alliance's 61st Mobile Infantry, Nien Nunb, a Sullustan resistance member, escorted the rebel soldier to the mining hangar to convene with the other members of the resistance.
The 2015 novel Battlefront: Twilight Company, penned by Alexander Freed, featured the mining hangar.
