The Cube

As seen in the Cosmology Chart, the Cube is the whole existence of the world of Tethys. It encapsulates everything, from the many Planes, Demiplanes, Conduits, Elemental Planes, Evergreen, Shadow Reflection, Material Plane and many others. It binds the Gods and safeguards them from the outside world, which is the Everchaos, which wants to annihilate existence, while the Cube swims around between other Spheres in the Space Between Stars.
