If Annan hadn't heard the greatest secret about the Lady of Silence, the Lady of Mystery, and the Goddess of Cup from the Sacrificial Saint—Henry Walden, "the one opposed to himself," he might indeed have had some difficulty unraveling this nightmare.
However, Annan just happened to know this secret.
—The Lady of Mystery was once the daughter "Sibyl" was about to give birth to, the one she sacrificed to "the Night," along with her womb.
It was because of this sacrificial ritual that the Lady of Mystery, the god of rituals, was born… It was also because "the Night" imparted some of its power to the Lady of Mystery that it was demoted from "the Night" to a god.
This event occurred in an era before the birth of mountains, rivers, and streams.
Sibyl, as the first flesh-and-blood being in this world, was only able to establish "the path of blood and desire" on earth after completing the sacrifice. Only after that did new life begin to be born.
