A sinister cloud has appeared on the edge of the solar system, and seems to be moving closer. The closest planet, Georgium Sidus, has but two human inhabitants: the missionary Reverand Cruet and his daughter Charity. Their last communication: ‘Great danger— imperative that—’And then nothing. Art, Myrtle and family decide to investigate whatever monstrous force of darkness was hiding within the cloud. But how could they know what mothy horrors lay in wait!? Because the evil they discover is far beyond anything their imaginations could concoct. Now, with the Empire in dire peril, it’s up to Art (and his family, truth be told) to muster all their cunning and courage to try to Save It (again).
