Pressy's Tumble was an artificial asteroid field in the Pressylla system. It was once a moon rich with ore, but because the ore was too deep to mine, the moon was destroyed by an explosives engineer. The largest moon fragment then served as a base for mining operations, which provided its materials to the First Order. Shortly before the attack on Tuanul village in Jakku, Captain Phasma suppressed a strike at the mining colony there.
