Still on the heels of the Devourer cult, the heroes head to a distant, uncharted star system, where they find the ruins of an ancient alien city floating in the atmosphere of a gas giant. Exploring the ruins, they encounter the degenerate descendants of a highly advanced species that once controlled the alien superweapon the heroes are searching for. Through the legends and superstitions of these savage aliens, the heroes can piece together clues to the superweapon's hidden location and the key to unlocking its power-an impossibly huge megastructure that the Cult of the Devourer is intent on seizing!
