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 suspended above one another. 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 such crises occur in succession, they remain in place around Seireitei indefinitely until things are returned to normality.

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 is 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, as they can simply will it.
 * 2) Make a Royal Key by creating a Royal Guard.

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.
