A cave, or rather, an intricate, endless cavernous area that has breaks in the ceiling, allowing the constant full moon to shine inside the place, all branches of caverns meet in what Zaine considers the "Heart of the world." An impossibly large cavern, in the center of which is an breathtakingly beautiful underground lake, lit with a gentle glow from within. The ceiling of this room is carved so that the moon can be seen perfectly, the rays of this large guardian of the night sky reveal delicate flowers that are in fact crystalline in structure, gems such as Diamond, Sapphire, Rubies, and others can be found in these beautiful flowers, the lake's interior is in fact packed full of these structures and may be the source of the light within the lake.


This area is based upon Zaine's spirit world, he created it by hand with his shikai and bankai, one cannot enter without an approved escort, its location is hidden to all save other taicho. It has an unusual ability, it can manifest the zanpakuto spirits of those who train here


THis is where most bankai or dangerous training will be undertaken.
