The Eternal Triangle

Underground Meeting Hall

The Underground Assembly Hall is where the Central 46 meets. It is an octagonal structure located in a large open space within the main building, and was also referred to as the Diet Building. Beyond the entrance to this structure there is a staircase leading down into the hall. The benches and high-backed chairs of the 40 wise men are arranged in two concentric rings, one higher than the other, surrounding an open area. In the walls there are recesses with stairs leading up to them, where the six judges are seated. There are large banners on its walls. It has thirteen levels of protection to keep out or at least stall intruders.

Seijōtōkyorin

The Seijōtōkyorin (清浄塔居林, Tranquil Forest of Residential Towers; Pure Pagoda Forest) is where the Central 46's members reside. It is the only place in all of Seireitei that is completely off limits to all except the Central 46, no matter what reason they may have. The residences are tall, thin tower-like buildings with the entrance raised off of the ground and accessed via a short stairway, with a wooden walkway surrounding the building. There is a tall, narrow window in the wall starting just above the door that continues to the top of the tower. Little of the interior is seen beyond the entrance, with no furnishings visible. The area being referred to as a forest suggests that there are likely 46 of them has 46 towers. It is home to all the wise men and judges.

Daireishokairō

Also known as the Daireishokairō (大霊書回廊, lit. "Great Spirit Book Gallery") is a repository of all the knowledge and history of the Soul Society. This is another area to which access is restricted. As a result, few are familiar with its inner workings even among the captains. Only special circumstances allows entrance to this information.
