There are seven spheres whose aetheric densities allow them to be reached by the technology of Man. With the Earth as our reference point, the planets can grouped thusly:
The Postlapsarian Worlds, thither went the Nephilim and the Atlanteans following the Deluge:
Saturn: Ringed with the petrified and crumbling corpses of titans and monsters. A rebellious demiurge imprisoned in its litharge-colored mists.
Jupiter: The peripatetic court of the most convivial of monarchs in continual celebration. Visitors glide down from the several moons on bat wings to hunt giant beasts in a sea of endless, variegated storm clouds.
Mars: Empires clash, and machine brains compute the scientific perfection of eternal war.
There was once another world between the spheres of Mars and Jupiter, but the iniquity of its people destroyed it.
The Prelapsarian Worlds, closer to the Sun and the Demiurge that dwells within:
Venus: Torrid jungles and vast, shallow oceans. Strange and beautiful plant women.
Mercury: Blazing court of the heliocephalic Emperor, a Philosopher-King.
Luna: The pallid, coralline gardens and laboratories of the Fair Folk. The fae themselves, ashen, luminous, and moth-winged, and their insectoid Selenite servants.
