Transitive Planes

At a minimum, each Transitive Plane coexists with one or more other planes, a relationship oversimplified by stating that Transitive Planes are just used to get from one plane to another. The Drift has mysterious one-way connections to every plane, though those same planes can't access the Drift except through the same technology necessary by those in the Universe. The mists of the Ethereal Plane overlap the planes of the Inner Sphere, while the Astral Plane borders every other plane in existence like the backstage of the cosmos. Bright and dark mirrors of the Universe, the First World and the Netherworld overlap the mortal world, albeit often in bizarre ways such that a short distance in one might be a vast gulf in the other. The daring, wise, or desperate can utilize these planes to bypass barriers in the Universe or rapidly cross vast distances through much swifter travel.
