If you look around the reef you will see a total of 8 doors and an elevator that you cannot access. 5 doors are unaccessable due to their height and being used to access docked ships. 3 of the 8 doors however can be be used for social activities; the door next to brother Vance, the disciple of osiris can be used for a bar. One of the remaining doors can be accessed while Xur is at the reef, but has a conjoined door to the next room and a path leading to a hallway. The hallway could be used for player homes, apartments, or quarters and the connecting room can lead to a shop where you can trade with NPC's in a market. Just a few thoughts, what do you guys think?
