The former headquarters of the once exiled 14th squad.

A structure, like Los Noches, that was not created by those currently residing in it, but simply found by them. The Sanctuary, as it's called, is a mid-sized square building with an open air center section used as a meditation garden. The separate quarters are fairly equal in size without much decor save for furniture cut from various rocks and boulders found around Hueco Mundo. Around the structure is a reiatsu supressing barrier that keeps Hollows from detecting the reiatsu of anyone inside. This is where Du'o's Hueco Mundo Lab is located. Don't tred here if you are afraid of bugs, you've been warned.
