The refinery complex at Pressy's Tumble was a mining operation situated within the manufactured asteroid field known as Pressy's Tumble, found in the Pressylla system. The miners who worked there were under the authority of the First Order and initiated a strike as a form of resistance to the severe conditions of their employment. Captain Phasma, a Stormtrooper, executed the leaders of the miners, alleging that the New Republic had managed to infiltrate the facility, sowing discord among the workers. FN-2187, a cadet who was present during the execution, paused and refrained from discharging his blaster rifle at the miners. The execution resulted in commendation from Phasma for the cadet FN-2003, who had previously failed to meet Phasma's expectations.
