Rukongai

Rukongai (wandering soul city), also known as the Rukon District, is the largest portion of Soul Society and the most populated. It is divided into 320 districts (80 in North Rukongai, 80 in West Rukongai, etc.), each numbered in descending order on how far they are from the center; this results in the higher-numerated (and farther) districts decaying into slums.

Seireitei

Seireitei (The Court of Pure Souls) is where the Shinigami live. There are different districts in Seireitei, arranged in ascending order by the number of spirits leaving in an area; the more spirits, the more dangerous the area.

Gotei 14

The Gotei 13 is the organization which most Shinigami join, and one of the three main branches of military in Soul Society. It is split into thirteen divisions (hence the name), with several divisions having certain specializations. The Gotei 13 is subservient to the edicts of the Central 46 Chambers. They also have no jurisdiction over any of the noble families.
