Polyhedron

Polyhedron was originally a publication of TSR, Inc.'s Role Playing Game Association (RPGA) that sometimes included articles concerning West End Games Star Wars: The Roleplaying Game. Following the RPGA's acquisition by Wizards of the Coast, it became a publication dedicated to d20 system games such as Wizards of the Coast's Star Wars Roleplaying Game. In all of these incarnations, the publication provided missions, game statistics and background material for gamers.

In 2002, Polyhedron became a section of Dungeon magazine. It continued to run until August 2004, when Dungeon editor Erik Mona discontinued Polyhedron and refocused the magazine purely on Dungeons and Dragons content.

Within the continuity of Star Wars Legends, issues from the single issues of Polyhedron are non-canon but may contain ambiguously canon elements, while issues printed after the merger with Dungeon are canon.

Despite originating prior to April 2003, and being deemed "unofficial" by Leland Chee, the planets Mandrine and Shar'Ack were included in 2009's The Essential Atlas. Mandrine later became canon with its inclusion in 2018's Solo: A Star Wars Story: Tales from Vandor by Jason Fry.
