Quarney Key was an island in the Middle Chain of the Gem Cities of Kwenn on the planet Kwenn. The island contained a nature preserve and served as the gateway to the exotic chains of the north sports waterfalls and caves that were crafted as part of the Grand Renewal. A dock for the Pelagic was also situated on the island, containing Otto's Grotto, which served fresh fleek eels. Quarney Key was connected via bridges to Langdam Key and elsewhere on Kwenn. The Filthy Credits pirate gang were present on Quarney Key, where they purchased orokite nodules stolen by poachers on the illicit market.
