Location from Bleach by Tite Kubo
The Hollow dimension — an endless white sand desert under eternal night and a crescent moon, where Hollows evolve and devour each other in a cycle of consumption.
Hueco Mundo is Kubo's masterpiece of negative space. The entire dimension is drawn in blacks and whites — no color, no warmth, no life in the conventional sense. Hollows wander the surface hunting each other, consuming to evolve: Hollow to Gillian, Gillian to Adjuchas, Adjuchas to Vasto Lorde. Beneath the sand lies the Menos Forest, a subterranean woodland where Gillian-class Menos Grande lumber in the dark like living skyscrapers. Aizen chose this wasteland as his staging ground precisely because it was forgotten — he built Las Noches at its center and filled it with Arrancar he created using the Hōgyoku. After his defeat, the dimension returned to its original emptiness, Hollows resuming their eternal cycle.
Infinite white sand dunes stretching to every horizon under a permanent black sky. A thin crescent moon hangs motionless overhead, casting pale light that makes everything look bleached and dead. Quartz-like trees dot the landscape — leafless, crystalline, casting no shadow. The silence is total except when something is hunting.
