Rylorii Minor was a planet dedicated to mining and maintained neutrality. It was situated in the Western Reaches of the galaxy. In the era of the Clone Wars, a senator representing the Galactic Republic convened with mayor Lup to discuss a potential trade pact. This agreement was ultimately formalized following an unsuccessful attempt to assassinate Lup.
The debut of Rylorii Minor occurred in the comic "Trade Relations", which appeared in the eighth issue of Star Wars Adventures, published in 2021. An aide mistakenly called the location Arkania Minor at one point.
