Feldrona, a planet, existed within the Feldrona system. This system was situated in the Glythe sector, which itself was located in the New Territories region of the Mid Rim. It was at some point in the past colonized by members of the Zabrak species who originated from the Glythe sector planet of Iridonia.
Following its establishment in 130 ABY, several colony worlds under Iridonia's control mounted rebellions against the newly established Galactic Empire, which was then under the rule of the Sith Lord Darth Krayt. The Empire's response was to obliterate two of these colonies using orbital bombardment. Subsequently, the remaining five colonies yielded to the Imperial forces. As a consequence of the colonies' acts of rebellion, the Sith Lord overseeing Iridonia and its colonies issued a decree: Feldrona would be transformed into a heavily guarded Imperial [prison](/article/prison/legends] world. The planet was then isolated and repurposed as a place to exile criminals.
The sourcebook Legacy Era Campaign Guide, released by Wizards of the Coast on March 17, 2009 for the Star Wars Roleplaying Game, introduced Feldrona. The reference book The Essential Atlas, published on August 18, 2009, identified the Feldrona system, and therefore Feldrona itself, as being located within grid square J-7.
