One of the outer systems of the Brema sector, Sullust holds claim to three planets, two moons, and a single star. The system is well known for its main inhabitants, the Sullustans. Excellent navigators and extremely impressive architects, the Sullustans have made a name for themselves in the annals of galactic history.

Of the three planets within the Sullust system, only one is home to life. The home planet of the Sullustans, called Sullust, is a volcanic world filled with caverns in which the Sullustans live. The closest planet to the Sullust sun is known as Sullumun and is better known for its hot temperatures and an extremely thick atmosphere. The other gas planet is similar, Lununmo. The orbits are the exact opposite of each other and they pass within several hundred thousand kilometers of each other at least twice a year.

Economically, the Sullust system survives off the trade of random minerals and other items not often found in the galaxy. Large mineral deposits can be found both on Sullust and its satellites Umnub and Sulon. The planet of Sullust itself has a high income which results from visitors with an interest in the great caverns of Sullust. The caverns are the actual cities of the Sullustan species and their architecture is amazingly beautiful to the casual visitor.

There are many training academies for Sullustans who wish to join the galactic community as navigators and pilots. Specializing in freighters and other small to medium craft, this valuable resource is used extensively by many corporations that require transportation specialists. Also, the occasional Sullustan architect will be hired to help plan a future underground colony.
