Neptune
On Neptune, the characters could dive deep into the mystical seas to discover long-forgotten technologies and magical artifacts of the ancient Aquan civilization. In ancient, sunken cities, secrets and dangers lurk in equal measure, and rival research groups could impede their progress.
Venus
Venus, shrouded by steaming jungle, is a paradise full of strange flora and fauna—as well as ancient ruins that harbor the secrets of a vanished high culture. The characters could be in search of a legendary Major Arcana, as they navigate dangerous terrain and contend with deadly creatures.
Mars
Mars, with its vast deserts and ancient pyramids, is a place full of archaeological wonders. The characters could find ancient scripts and maps that point the way to a secret underground city. But they are not alone—ruthless plunderers and mysterious cultists follow them at every turn.
Saturn
On Saturn and its rings there are hidden mining stations and secret outposts that host astonishing metallic resources and rare elements. The characters could, in their hunt for a rare mineral, become entangled in the intrigues of competing mining companies and in dangerous encounters with space pirates.
Mercury
The inhospitable Mercury with its extreme temperatures and unforgiving environmental conditions guards dark secrets. Perhaps the characters will discover clues to an ancient, forgotten colony, whose remnants harbor valuable technologies—and ominous warnings of an impending catastrophe that still slumbers deep within the planet. Or they will become entangled in the disputes between landowners, mine owners, and unionists.
