Chamber of Darkness

The Chamber of Darkness is a special area that appears below the Ame-no-mihashira. This room is only accessible by the user of the Six Paths: Ame-no-mihashira, namely Ryo, and by those who possess chakra reserves comparable to that of a god's. Anyone else who enters will have a feeling of excess gravity, bringing them to their knees, while also having their chakra absorbed. Sooner or later, the poor person will be a completely decayed mess as the tree absorbed their chakra. Access to the room itself is forbidden due to the fact that the entrance to it changes locations every five minutes.

Appearance
The room is a very large cylinder. Ethereal stairs run up the left and right sides of the chamber. The ceiling of the room is composed of the roots of the Ame-no-mihashira. The floor is a giant yin-yang representation.

Use
This chamber was recently discovered by Ryo when he went to inspect the tree he had created. Upon entering, Ryo felt weakened and knew what this chamber could do. He then brought up the attention of the chamber to his siblings who agreed with him to keep the room itself a secret. Ryo then decided that the room could be used for interrogations as the tree sucking out chakra could be used as a torture device. However, any other access to the chamber was forbidden.

Trivia

 * This is based off of the chamber with the same name from Twin Star Exorcists. The location and function of the chamber is the same but I changed it to suck out chakra which the TSE's version did not do. TSE's version also only allows those with high chakra to enter too, although "chakra" in TSE is known as "Spell Power".
