Thermon, a world found in the Thermon system of the Mid Rim, was classified as a planet that possessed numerous moons characterized by geysers emitting methane.
Nevertheless, the Juvex sector Houses had placed the planet under embargo. Initially designated as a penal colony by these Houses, control subsequently shifted to the criminal organizations imprisoned on Thermon. The Houses' efforts to regain dominance have paradoxically increased the allure of smuggling the planet's ore for various smugglers.
