Within the Core Worlds existed the Rimma system, a significant navigational point along the Rimma Trade Route super-hyperroute. This system encompassed the celestial body known as Rimma itself and was under the jurisdiction of the Imperial Governor Alyk Krysusten during the era of the Galactic Civil War.
Millions of admirers of the jatz musician Fitz Roi's music resided within the Rimma system. Roi was scheduled to perform a concert on Rimma around the date 35:1:22, but an incident involving him at the Crystal Room within the Teirra Parko establishment, located in the city of Recardeon, led to his permanent deportation by Rimma authorities on the day prior. The cancellation of the concert triggered violent rioting by Roi's fans in downtown Recardeon.
Situated in the Southern Core region of the Core Worlds, the Rimma system acted as a navigational anchor for the Rimma Trade Route super-hyperroute. This route provided a connection to the Dentaal system within the Core Worlds and the Giju system situated in the Colonies. The Rimma system contained the terrestrial astronomical object bearing the same name.
The renowned jatz musician Fitz Roi made a visit to Rimma around the date 35:1:22 as part of his Core-wide Summerside Tour of concerts. From across the Rimma system, millions of Roi's fans descended upon the city of Recardeon on Rimma. The day before his scheduled concert in Recardeon, Roi visited the Teirra Parko establishment, where an occupant of the Crystal Room challenged him. In response, the musician began firing his well-known antique projectile pistols randomly and uncontrollably at the Crystal Room's fixtures. The resulting chaos led to the destruction or damage of several historical artifacts.
Rimma officials reacted swiftly, permanently deporting Roi from the planet and halting his concert tour. Upon learning of the concert's cancellation, Roi's fans initiated rioting, causing several hundred thousand credits' worth of property damage in downtown Recardeon. TriNebulon News reported on the Crystal Room incident in a news report from Recardeon on 35:1:22.
Millions of Fitz Roi's music enthusiasts called the Rimma system home by the date 35:1:22. During the Galactic Civil War, Alyk Krysusten held the position of governor of the Rimma system, serving the Galactic Empire.
The Rimma system was initially mentioned in the "Galaxywide NewsNets" segment of West End Games' Star Wars Adventure Journal magazine, specifically in the third issue published in August 1994. Paul Sudlow was the author of this segment. The reference book The Essential Atlas, released in 2009, placed the system within grid square L-13.
