But conversely...
Annan narrowed his eyes slightly.
The existence of the "Eternal Maiden" Ingrid was extremely important.
Not just because she was a "hidden mirror."
It was also because her presence confirmed some of Annan's previous speculations...
You see, Annan's Book of the Celestial Chariot consisted of only six pages. Each page of the Book of Truth contained one truth.
According to the normal process of the Sublimation Ritual, Annan had to choose one or two truths from the six during his sublimation. Then, he would return the remaining truths to the Pillar of the World in the Realm of Light to create other Books of Truth.
These one or two truths would eventually become fixed in the sublimated soul, forming a divine office.
Then, according to the theory of "Light Born from the Mirror," Annan had to shatter six mirrors to gather the complete Book of Truth and to obtain all the truths of the Celestial Chariot.
But beyond these six mirrors, there was a seventh mirror.
