It currently serves one purpose, being an area for Badum to issue tutorial quests from, akin to the Factions' HQs. Once the initial missions are complete, nothing can be bought or sold here, and no new quests will be given.
NPC prospectors populate the bar. They cannot be interacted with and they do not move from their sitting positions.
There's a dancing Co-Bot hologram at the bar. You can interact with it to change the way it dances.
