- "Friend of mine saw her at a gaamja match in the Oseon Belt last cycle. Apparently she tried to palm the disc. They kicked her out of the whole system for that one."
- ―A Rodian, on Zana Gatta
The Oseon system was a part of the Outer Rim Territories' Centrality region. It was situated on the Sanity Skip hyperspace route and contained the Oseon Belt as well as a subtropical moon therein. The pirate queen Maz Kanata noted the system as a location of interest on a map she included in the book Smuggler's Guide, and at one point by 10 BBY, the gambler Lando Calrissian won the ownership of the Oseon Belt moon in a card game. By thirteen years later, the gambler Zana Gatta was expelled from the Oseon system for apparently breaking the rules in a match of the gaamja game.
Description[]

The Oseon system lay at one end of the Sanity Skip hyperspace route.
The Oseon system was situated in the Centrality, a part of the regions known as the Outer Rim Territories[1] and the Slice.[2] Located in grid square T-8 of the Standard Galactic Grid, it lay on a hyperspace route that connected it to the celestial bodies Junkfort Station[1] and Marleyvane.[7] Another route, known as the Sanity Skip, also linked the Oseon to the Kessel system.[5]
The Oseon system contained the location known as the Oseon Belt,[3] which in turn was the site of a subtropical moon.[4] The system also shared its name with the deadly radiation wave known as the Flamewind of Oseon[8] as well as the Oseon leatherette clothing material.[9]
History[]
- "So… which casinos haven't banned me yet? Relatta, Pavo Prime, the Oseon, Zirtran's…"
- ―Lando Calrissian, Smuggler's Guide

Zana Gatta was expelled from the Oseon system for an apparent breaking of the rules of the gaamja game.
The pirate queen Maz Kanata marked the Oseon system as a location of interest—as well as denoting the Sanity Skip on which it lay as one of the "real" trade routes to be used by smugglers, as opposed to the official routes—on a galactic map that she included in the book known as the Smuggler's Guide. When the human gambler Lando Calrissian acquired the book[5] at some point by 10 BBY,[10] he noted the Oseon in a list of casinos that at the time had not yet banned him from playing games there.[5] By that same year,[11] Calrissian also won the ownership of the Oseon Belt's subtropical moon in a card game.[12]
At one point by thirteen years later,[13] the human gambler Zana Gatta participated in a match of gaamja in the Oseon Belt. For an apparent breaking of the game's rules, Gatta was expelled from the Oseon system.[6]
The following cycle, a Rodian told the latter fact to the thief Kay Vess.[6]
Behind the scenes[]

The Oseon system's asteroid Oseon 6845 in Star Wars Legends
In the current Star Wars canon, "Oseon" was introduced as a location on a galactic map in Star Wars: The Force Awakens Beginner Game, a 2016 Fantasy Flight Games' Star Wars Roleplaying boxed set.[1] The star system was first identified by name by "Lando Calrissian and Other Characters From the Galaxy," a booklet of the Star Wars Encyclopedia series published by De Agostini[4] on July 22, 2022.[14]
The star system originated in the Star Wars Legends continuity, where it first appeared in Lando Calrissian and the Mindharp of Sharu,[15] the June 12, 1983[16] first entry in The Lando Calrissian Adventures trilogy of novels by L. Neil Smith.[15] On the original cover of Lando Calrissian and the Flamewind of Oseon, the trilogy's[17] September 12, 1983[16] second entry, an illustration by William Schmidt provided the first visual depiction of the system's asteroid Oseon 6845.[17]
