The Nentan system lies within the Glythe sector, in the Mid Rim close to the Unknown Regions. The sector plays host to a Centrepoint base.

The Nentan system in itself is home to four celestial bodies when including the system’s sun. Each of the planets is unique and has its own defining characteristics. The planets in the system all share a very high-speed orbit when compared to most other systems. This high-speed orbit is crucial to both the survival and the prosperity of the system.

The orbital velocity also enables one of the most unique sights in the galaxy. There are two planets in the system that have an almost identical orbit. For a short period out of the year, these two planets pass so close that the atmospheres literally brush up against one another causing spectacular electrical storms. If it would not be for the high-speed orbit, the gravity that each of these planets exerts on one another would cause them to collide.

The system's close proximity to the Unknown Regions is a double-edged sword. The vast unknown gives the system untapped potential, the undiscovered systems could contain the galaxy’s wealthiest planets. The neighboring regions could also cause Nentan to be the gateway to the largest period of exploration and commerce that the galaxy has ever known.

However, on the other hand, this proximity to the unknown regions also has multiple and quite often severe downfalls. This proximity to uncharted and ungoverned space makes it a prime selection for piracy. This same aspect quite often leads to many people who are running from the empire, the rebellion, or both to attempt to hide out here. Theses aspects quite often lead to a lack of interest in the system, as many people are not willing to take the risks of a settlement in this area. The neighboring systems being so mysterious also leads to a lack of willingness to settle for fear of invasion. The regions that remain unexplored could be home to a highly advanced and overly aggressive race.

The system is currently home to a relatively large tourism industry with a permanent population of almost a billion beings. The system is also home to a large scientific community that is dedicated to the exploration of this system as well as the neighboring regions. The scientific community is diverse and numbered at millions of individuals.
