Hueco Mundo

Hueco Mundo is a dimension between the human world and Soul Society. It is where hollows reside when not hunting humans, and they are undetectable as long as they remain inside. Entrances to Hueco Mundo are created by ripping the dimensional fabric between the two worlds. On the surface of Hueco Mundo is a desert-like realm, covered in perpetual night. The little vegetation that meets the eye is actually formed from crystal; and while the sky has clouds, there is no water to be found anywhere. Few hollows reside on the surface, and the landscape is dominated by the imposing Las Noches palace. Directly underneath is the Forest of Menos, where the hollows mainly reside until provoked to leave.
