Planes

Each "Plane of Existence" is really just a planet within the massive system surrounding Khorshid. Each planet has at least one moon, a fragment of Selene, leading the Planets further out from Khorshid to become stranger and more chaotic. Nowhere is this more apparent than on Mechanus, the planet closest to the Sun, the Plane of Order and Law; or Limbo, the furthest from Khorshid, surrounded by so many moons, that the planet itself has less mass than them combined. Limbo is the plane of pure, raw elemental chaos.
