Twin Chambers

The twin chambers are two intangible locations within the bodies of those born to modern mashi or bandire. These chambers are the source of the aforementioned's yuchaku although it primarily resides in the telluric chamber, with the ethereal chamber becoming active under special circumstances.

Telluric Chamber
Yuchaku primarily resides and is utilized from the telluric chamber, the primary stores. Although little is known about the chamber, research done by Apollo and Demeter has shown that the shape of each individual's chamber corresponds to their controllable(s).

Ethereal Chamber
Normally inactive and undetectable, the ethereal chamber activates only when people make an active attempt to transfer yuchaku into it by "tuning in to the special frequency", this in turning causing the person to enter the Empowered State.
