The Stones

Eight stones are needed to activate the Shrine: The Stone of Fire, the Stone of Earth, the Stone of Air, the Stone of Water, the Stone of the Angel of Life, the Stone of the Angel of Death, the Stone of the Sehora and the Stone of the Perfect Magican. To active a stone, a magican belonging to that stone must go through a series of tasks, usually involuntarily.

On top of the eight shrine stones, another four stones exist surrounding life: the Soul Stone, the Mind Stone, the Sense Stone and an unknown one.
