The Great Beyond
A vast swath of uncharted, unclaimed terrain that metaphysically borders and surrounds each of the planes in the Outer Sphere. This plane is dangerously chaotic and untouched by the Gods. When entering the Maelstrom from another plane, it appears much like its neighbor. The further a traveler traverses from the stabilizing anchor of the Borderlands, the terrain falls back into the mutable freedom known as the Cerulean Void. The Maelstrom defies cartographers, as its very essence shifts and flows like the tides of an unseen ocean, with the Borderlands acting as calm shores and shallows.
