Crystal Sphere

The crystal sphere is a prodigiously huge, not-entirely-euclidean (and thus not literally precisely spherical, at least not from within) megastructure which encloses the Material Plane. The sphere wall has no gravity and appears to be impossible to damage by any normal or magical means. The bright lights of the stars are inscribed across the interior of the crystal sphere, while the sun, moons, and Wanderers are physical objects that travel within it.
