Hangar Bay 631-D was a hangar that was located in the Bilbringi Shipyards. Circa 12 ABY, the bay was occupied by a Firespray-31-class patrol and attack craft that was acquired by the rogue Jedi student Dal Konur, and Konur began preparing the ship for a mission that he planned to go on. However, he was confronted in the bay by a group of agents that Jedi Master Luke Skywalker had sent to find him.
