The Book of Onei is an antinomian dream grimoire, providing deceptive yet true information about the art of Oneiromancy or dream magic in the form of poetry, fantasy, and intentionally ambiguous instructions.
You’re going down into Death, down into the power that made Time!
I myself am afraid of it.
The Veiled One is an ancient and terrifying old woman, “veiled” in the sense that her facial features cannot be clearly seen. In this, she is like one of the Legion, the Archons who control the world through the control of dreams.
She is the keeper of the Book, and she bestows it upon whomever she chooses. She can also teach many secret skills, but all of her wisdom is dangerous in one way or another. She stirs a whirlpool or cauldron made of swirling stars and galaxies. There is a black hole at the center of it.
