The priestess' pain is reflected in the Mirror of Loss.
The commandment must be placed upon the priestess' empty eyes.
If tattoos should enter her eyes, the empty eyes will become mirrors and all her pain shall be unleashed.
If the commandments break and the priestess awakes, the gates will open and the Rift shall spill forth from the Chamber of Thorns.
The Rift which spills forth will pass through dreams into the world and love shall be consumed by torment.
