Citadel Station

Citadel station

The Citadel is a massive space station, constructed over 50 millennia ago in the Widow System. No one knows who created Citadel but many speculate that is was the Puppeteers or perhaps the Annunaki.

  • Total Length (open): 44.7km
  • Diameter (open): 12.8km
  • Thickness of Ward Arms: 330m
  • Presidium Diameter: 7.2km
  • Exterior Armor Thickness: 13m
  • Gross Weight: 7.11 billion metric tons
  • Population: 13.2 million (excluding keepers and duct rats)


In a brief encounter with the Q, a Ferengi Captain named Jok discovered the station. He brought in hundreds of exploration teams and claimed the station as his own under salvage rights. The Romulans discovered the station nearly ten years later and attempted to capture the station but the station’s automated defense system destroyed the Romulan fleet. Over the next seventy years the station slowly became a massive trade hub. Eventually Jok sold the station. He split the station into 1,000 shares and offered them up to the highest bidders. In a strange quirk of imagination, he sold no more than one share per person or government.

Citadel Station now houses numerous embassies, markets, businesses, and military garrisons. The Romulans try from time to time to take over the station, but have failed in every attempt. Currently, the station is run by the Citadel Council, which consists of nine members who have managed to gain a combined ownership of 60% of the shares. The Council is recognized as a legitimate government by the UFP and most other interstellar governments.

The precise age of the station is unknown, nor is the resilient material it is constructed from. The location of the Citadel’s core and its master control unit, which regulates systems such as life support and navigation, remain hidden. The most visible, and perhaps intriguing, mystery of the Citadel concerns its caretakers, the Keepers. These mute alien creatures maintain the Citadel’s vital systems, and can be seen working throughout the station; despite this, little is known about them.

Currently, shares are selling at auction for approximately 10,000 bars of latinum. Share owners gain 0.1% of all profits the station makes.


The Citadel is a massive construct, similar in shape to a pentagram. It consists of a central ring 7.2 kilometers in diameter, from which five arms protrude, each 43.6 km long and 330m thick. The station is capable of closing in on itself, via the convergence of its five arms, transforming it into a long, impenetrable cylinder. However, the Citadel is only closed in times of emergency, and normally the station retains its ‘open’ appearance. The central ring and five arms are home to the Presidium and Wards respectively; the spaceports are also located on the central ring, as it is the center of rotation, facilitating easier access for ships attempting to dock with the station.


The Presidium is a massive, park-like complex containing the offices of the various branches of the galactic government, as well as the embassies of all the races represented in the Citadel. There are also shops, restaurants, and recreational facilities serving the wealthy residents who live and work throughout the sector. The Presidium is monitored by an artificial life form named Avina, and, unlike the Wards, incorporates an artificial 20-hour day schedule: lights are dimmed, and the holographic ‘sky’ darkened, for 6 of the 20 hours, imitating the familiar day-night cycle.

Citadel Tower

The tower at the center of the Presidium houses the Council Chambers and the main traffic control for the station – any ship within one parsec comes under the jurisdiction of Citadel Control. The Chambers themselves are not open to the public, and access is only granted to officials and those with special clearance. They are beautifully furnished, with cherry trees and fountains, as well as numerous staircases leading up to the central platform where the Council convenes.


The ‘arms’ of the Citadel, known as the Wards, constitute the residential and commercial sectors of the station. Densely populated, housing millions of residents from many galactic species, the Wards are akin to Earth cities such as Hong Kong and Singapore. Numerous skyscrapers rise from the superstructure, sealed against vacuum, as breathable atmosphere is only maintained to a height of approximately 7 meters. Unlike the Presidium, there is no artificial day-night cycle; as a consequence of this, commercial activity rarely ceases, and residents work and rest according to personal need. The Wards are policed by the Citadel Security Services (C-Sec), whose offices and custody suites are located in the Lower Wards. Flux is a popular night club, also located in the Wards.



Duct Rats

Duct Rats are poor, homeless children of the Citadel who travel in the ventilation system of the station. They often die by being crushed by the fans, starving to death, or suffocating because of exposure to the open vacuum of space. Often times, they are just never found.


The Keepers are a mysterious, bio-engineered insectoid race that are native only to the Citadel. They are found throughout the Citadel in random locations, and are harmless.
