Sibyl

The Sibyl is the guardian of Fairyland-Below, and acts as the doorway there.

History
The Sibyl, even as a child, knew of her destiny to guard the way. She would ask her parents riddles, troths, and all kinds of prices.

When she grew up, she went to Asphodel to act as the doorway to Fairyland-Below. There she lived in an elevator, under four names, The Sibyl of Comfort, The Sibyl of Comeuppance, The Sibyl of Cruel-But-True, and The Sibyl of Complexity. Whichever name a quester chose, she would act accordingly.

She met September when she was trying to go to Fairyland-Below to stop her shadow, Halloween, from stealing all the magic from Fairyland. The Sibyl told her about what it was to be a Sibyl, prepared her for the underworld, and gave her the Red Wind's coat.
