Okay, so anyone not attending the opera, give an idea about what kind of place you would like to head to. Port New Haven is a former pirate base which was a former wayfarer station. It is has been expanded to include everything a way station to the unknown needs, with a population just shy of a million.
It is protected by powerful weapon systems, at least two naval frigates and whatever Trader vessels might be nearby.
The central area where the opera will be held is the governor's palace, literally in the palace itself, next to the grand cathedral. This is an area of wealth, but also for commoners, both to receive the emperor's blessing at one of the 24 masses held daily, once per hour, or to witness those being punished in the central square on the pillars of righteousness.
In a ring, out from the cathedral is the Path to the Throne, a thriving marketplace of large stores and small stalls, offering many interesting goods and services. The further from the Cathedral, the more dilapidated side tunnels become, until you reach the general docking port for small vessels.
The cathedral is next to the Naval Quarters, where naval personnel are housed and the astropathic choir sits. Here the patrol paths are plotted for the navy to the handful of controlled systems in the expanse. There is also a naval dock with advanced repair facilities.
Past the governors palace is the heart of the station, hydroponic farms, power stations and manufactoriums. While much of what is supplied at the station comes from elsewhere, the station is self sufficient to a degree. This is also the most common area for lowly workers who do the drudging labor while overseen by tech priests and nobles. A shrine to the station's machine spirit is house somewhere in the tangle of structures. (legal fighting ring likely)
Above and below the station are great pylons to which most voidships dock, docking above station is generally considered an honor.
Lastly is the ruined sector, damaged decades ago when the station was first reclaimed it has seen a period of growth and reconstruction then abandonment. While there are dark areas all over the station, this is a large area where those better left forgotten dwell. Illegal small ship space docks and xeno establishments are rumored. (illegal fighting ring certain)
A fortified section branches off to the side of the station, the quarters for Imperial guard and other warriors not generally welcome on the station.
