Saturn moves in the furthest sphere from the Sun reachable by the starships of Man. Beyond, the Cosmos is more chaotic and the laws of Nature are strange. Saturn and those more distant spheres are remnants of a renegade cosmos that was or perhaps might have been. In that world, Saturn would have been the sun and a source of life instead of a graveyard and place of death.
Unique among the planets are Saturn's great rings made of the petrified remains of titans and monsters and the dust and remain made from their collisions in the void. The greatest of these pre-Creation monsters form the moons of Saturn. Men sometimes find treasure among these cold, sepulchral bodies, but ancient and malefic intelligence still lives in some, and there are tales of the dead becoming animate in their influence.
Some seek riches within Saturn itself, but its sickly yellow vapors streaked with dull gray can only be safely penetrated in thick, lead diving spheres that afford voyagers protection by alchemical affinity from both the crushing pressures and the saturnine radiations. Without them, living things petrify then turn to dust and other metals and materials corrode or decay. Travelers have recounted hearing the voices of souls, and ancient and damned, raging or crying in the dark mists, but whether these things are real, no one can say.
At Saturn's north pole, there hangs a great cube of stone like black onyx. Inside, dwells the Oyarses spirit of Saturn, long-bearded Aratron. He has made a great study of time and death, and is to possess a laboratory where he grows new physical forms for himself that he transfers his intelligence to him the old one succumbs to death. As well as being Aratron's palace, laboratory, and treasure house, the cube is said to be the tomb of the rebellious titan that created this world--or at least what is left of him. Though his giant, apparently-dead form has been accreted with stone, he is still well bound and meant to be for eternity.
