A thousand miles away from Las Noche lies a mountainous terrain with less sunlight, life form and vegetation. Mountains that soared upward as if determined to kiss the heavens were sights one would see from a long distance. The deserted landscape is known to be over populated with high steep rough mass of rocks and serrated mountains clustered together like they felt cold and gave no room for habitation. Within this barren land are narrow pathways that can be misleading to those that attempt using them as a route to get to other regions of Hueco Mundo. The air was always chilling and numbing, and carried an unpleasant stench of death/horror due to the never ending darkness and silence.
However, deep within one of these crags lies a sacred temple known as THE HALL OF REBORN. A place where hollows in search of greater strength seek to attain power. A place where one of the Arrancar most hallowed tradition ('Unmasking Ceremony') takes place. On getting to the ideal location, you will be welcomed by a massive temple like structure built from the mountain itself. It has a single entrance and carries a couple of windows with attractive designs.
The entrance is protected by the everlasting powers of the Hogyoku which projects an invisible barrier over the entire entrance to keep away anything not hollow from gaining passage into the hall. Once inside the hall, your eyes would meet the magnificent architectural design of the interior which one must say is marvelous. Just as the Espada had instructed, the architects and engineers built an astounding abode large enough to contain an entire legion of hollows for the purpose of the unmasking ceremony. In it one would see a flight of large round pillars that run down the hall on each side with a well decorated ceiling. The floor made of marble will further strike ones eyes with wonder as it glitters endlessly.
At the extreme end of the temple lies two thrones made of stone specially built for Celise and Luna, which can only be seen if one gets close enough considering the massive length of the hall. On the left armrest of both thrones are small computerized buttons which are used to input basic commands and also channel the power of the Hogyoku for ritual to commence. The buttons are fingerprint oriented, so therefore can only function in the hands of an Espada.
With the press of a button, the floor before the throne will slowly divide in two, in the process will allow several large receptacle structures emerge from beneath; dependent on the number of pods needed. These Cryo-tube like pods are responsible for the transformation process in collaboration with the ultimate power of the Hogyoku.
