Altar of the Absolute Boundary

Located in the center of the Ido Front, the Altar of the Absolute Boundary is an elevator-like connection between the 5th layer and the 6th layer.

The Altar can only be activated if an owner of a personal Life Reverberating Stone uses his stone while being inside it.

Trivia

 * The entrance to the elevator-like system is covered with some sort of membrane.
