Quarney Key existed as an island found within the Middle Chain of the Gem Cities of Kwenn on the planet named Kwenn. This island was home to a protected nature area and functioned as the entrance to the breathtaking northern chains, boasting waterfalls and caves created during the Grand Renewal. The island also featured a docking area for the casino sail barge known as Pelagic, which housed Otto's Grotto, a provider of freshly prepared fleek eels. Bridges linked Quarney Key to Langdam Key and other locations on Kwenn. The Filthy Credits pirate group maintained a presence on Quarney Key, where they acquired orokite nodules that had been illegally obtained by poachers and offered on the illicit market.
