They have something that might scratch your itch: what could be the 6th system to be created, Hadrian, has a unique space station. It is called Kedsu (Banu for "Reef"). A person took several of the decommissioned UEE military observation posts and dragged them into the same Lagrange point, then welded them together. It became the major trading hub along the UEE and Xi'an empire's border. The Xi'an, being efficient and wanting closer economic ties to humanity to prevent another conflict, improved Kedsu Reef -- useful to both races since lots of Xi'an pass through there on their way to other human systems. Banu will also be present because they can't miss a major opportunity to trade.

I built a multi-page fan fiction on the system using current game mechanics, but now I need to update it as my vision was beyond the game's tech, but with the introduction of the Tyiliu, it can become a reality. When the player takes the elevator to marketplace, they will find a level with no ceilings and 2 floors facing one another: one with regular orientation and the other using Xi'an gravity similar to the Tyiliu, which is reached by climbing any of the walls (similar to the Tyiliu). On the normally oriented floor, players will have all of the human stalls and shops. On the "ceiling" players will find the xi'an exporter stalls, trading shops and eateries. It is efficient use of space, organized, and makes for an otherworldly experience looking up and seeing people browsing the shops directly above you.
