Hueco Mundo

Hueco Mundo is an endless white desert with dunes and rocky formations. The sky here is always dark, and the moon is in a phase opposite to that of the Earth. The atmosphere is saturated with spiritual particles, which allows weak Hollows to survive without absorbing human souls. Vegetation is absent, but tree-like minerals resembling quartz protrude from beneath the ground. Most inhabitants hide below the surface or in shelters and come out only when strangers appear or for some other necessity. There are no bodies of water in this dimension.
