Despite being around for several centuries, the Cyan star port has never received an official name. Cyan government has not been actively pursuing interstellar trade.
The primary administrative complex is a rambling structure, added to almost randomly over the years. The original control tower was abandoned more than a century before and is used for storage and the rare sight seeing citizen. The new tower, more than 80 years old, presides several stories above the old tower and give a good vantage over the entire port.
The massive customs building houses what appears to be hundreds of offices and officials. Security is very evident throughout this building, which is the primary way of leaving the port. Security checks are very thorough for a TL A egress. Returning to the port can also be a hassle depending on crowds, the mood of the local army at the time, as well as the latest edict from the dictator. There are dozens of warehouses nearby both inside and outside the fence, some of which are still not usable.
Accommodations are adequate, but not up to high passage standards. And in the current siege mentality, things are crowded. Most merchants do not leave the port, relying on local brokers for cargoes. The Marine squads are housed in one of the hotels, leaving even fewer spaces for visitors. Marines patrol the perimeter constantly, primarily to maintain a visible watch over the occasional crowds outside.
There is the constant sound of grav vehicles loading and unloading cargo. Despite being a class C port, it is on the leg to the subsector capitol so has a larger than expected number of ships. Additionally, the local SDB fleet is housed here, and make trips daily. There are two airport style runways, so that local aircraft can transport cargo or people. All has to be inspected by customs prior to leaving the port.
Startown was damaged in the riots of 5 years ago, and several buildings remain burnt out husks of buildings. Military patrols are constantly roving through the city, with more near the port boundaries. It is not as rambunctious as many startowns are, but still has quite the variety of people. There are still several brokers and trading guilds available in startown.
