Seireitei/court of pure souls

This is in the center of the soul society,its a circular shirô with four main entrances, each guarded by a Gate Guardian. The walls are made of deathstone, a material known to sap all spiritual and psychic energy when one portion is faced in a particular direction, similar to magnetic lodestones.

The majority of the residents of Seireitei(this place), nobility and shinigami alike, do not interact with the citizens of Rukongai. However, residents of Rukongai are allowed to apply for the shinigami academy, which is often the only escape from the poorest conditions of Rukongai.
