- Culture: Cosmopolitan. Illara Prime has been said to set the tone for the entire Region. Styles, culture, fads - the most important ones start here and spread throughout the expanse. The cultural level is unsurpassed: there are more museums, theaters, libraries, and centers of learning in the system than in the rest of the Expanse put together.
- Places of Note: Illara Prime's original surface is now virtually invisible, cloaked in a massive urban sprawl that stretches for kilometers under the ever-present stream of space traffic. Almost every surface of the world has been covered by a cityscape several kilometers deep. Uncounted billions live in the durasteel and plasticrete labyrinth. Beneath the opulence of the upper levels, the undercity gives life to all the excesses, abuses, and vices that would not be approved of in any civilized world. The city never sleeps. Throughout the day and night it bustles with activity.
- Ship Facilities: There are an unknown number of corporate and independently owned ship construction and repair facilities throughout the entire system.
- Other Details: Thousands of major companies have their offices and plants located on Illara Prime. The largest of these is Balivari Industries, owned by D'Taeon Maliin, which some believe is a front for the criminal organization known as Shadizaar. The 100 most profitable companies form a type of senate, in which they bi-annually appoint a Governor who is to look after all the municipal responsibilities. In reality, the general populace is unaware of and apathetic towards this choice, as no one can remember the last dozen or so governors, due to their lack of impact while in office. The megacorporations unofficially run their sections of the planet the way they want to.
