Seireitei History

Seireitei (瀞霊廷, court of pure souls) is in the center of Soul Society, a circular shiro with four main entrances, each guarded by a Gate Guardian. The walls are made of deathstone, a material known to sap all Reiryoku, similar to magnetic lodestones. The deathstone also forms a spherical barrier around the city, preventing anyone from entering anywhere other than the four gates. This stone also prevents the ability to gather Reishi underneath your feet to walk in the air whist within Seireitei.

The majority of the residents of Seireitei, nobility and Shinigami alike, do not interact with the citizens of Rukongai. However, residents of Rukongai, like Renji and Rukia, are allowed to apply for the Shinigami Academy, which is often the only escape from the poorest conditions of Rukongai. Some Seireitei residents, such as ex-commander of the Special Forces, Yoruichi Shihōin, and the Shiba clan, do maintain residences outside the castle.

At the center of Seireitei are the Senzaikyū (Shrine of Penitence), a white tower, and Sōkyoku (双) Hill, where executions take place.
