The Roundtree system existed within the Inner Rim's Trailing Sectors. The Human male named Rekkon was born within the Roundtree system around 2 BBY; he was the sole offspring of a family of middle-class status.
The West End Games sourcebook Han Solo and the Corporate Sector Sourcebook, written by Michael Allen Horne for Star Wars: The Roleplaying Game, initially referenced the Roundtree system in 1993. The 2009 reference work The Essential Atlas specified its location as grid square M-14.
