Soul King Palace

is the official residence of the Soul King, located in a separate dimension in the very core of Soul Society.

Overview
The Soul King Palace consists of several layers, with one layer suspended above the other. The lowest level is comprised from many buildings of the same style to that of Seireitei. From this, a large stairway leads upwards to a wide and flat expanse, with both areas at the base and top of these stairs being lined by rows of huge, circular pillars. Floating above are five discs with numerous buildings on each, while suspended higher still is a large cylindrical structure that has a conical top and bottom.

The sekkiseki walls that surround Seireitei are ordinarily intended to protect the Soul King Palace, instead meant only to fall down to Seireitei in times of emergency. However, if emergencies occur in succession, they remain in place around Seireitei indefinitely until things are returned to normal.

Admittance
The route to the inner dimension in which the palace resides can only be opened with "a key", fittingly named the, the location of which is kept secret, only being passed down verbally from one Gotei 13 Captain-Commander to the next. There are only two ways to enter the Spirit King Palace:


 * 1) With the permission of the Royal Guard. They don't have to be there physically, they only need to want the person to enter.
 * 2) Make a Royal Key by creating a Royal Guard.

A Royal Guard can also open up a to send someone directly to the human world, and use the same gate to send said "someone" back, but to do so requires syncing the arrival and departure times.

Transportation
The only known method to get from section to section of the Soul King Palace is to be catapulted into the sky, in the direction of the intended destination.

Guards
The Royal Guard, also known as the "Zero Division", are the protectors of the Soul King Palace and its residents, particularly the Soul King. Though they commonly remain within the palace, when the Royal Guard do need to travel, their preferred method of transportation takes the form of a huge pillar called the. While this pillar is able to freely exit the inner dimension, it is unable to return to the palace on its own and is instead entirely reliant on outside assistance to do so, such as Kūkaku Shiba's.
