The former Las Noches is a massive fortress which can be seen for miles in Hueco Mundo. It consists of a main building with a domed center surrounded by several large towers and smaller buildings.The fortress is complete with medical facilites and detention wings. This is a secondary base for Sin and the Espada to use if a threat may rise.
The landscape of Hueco Mundo is a seemingly never-ending white desert, with dunes like those of the Sahara. The desert is littered with what appear to be boulders and shriveled trees, but these are actually a form of quartz. This is also the area Hollows or Arrancar are sent if they have betrayed the King Of Hueco Mundo Sin.
