 was a lust spirit. While non-coporeal, her image appeared to Brianna Barter as a translucent woman with flame-red hair and eyes.

When Brianna was 12, she found a polished agate under the floor of her late Aunt Audrey's cottage. She slept with it, and had it set on a silver chain, to wear. The spirit within the stone sent dreams to Brianna, promising powers and beauty in exchange for sharing her body.

Two and a half months prior to Brianna's capture by Reverend Evangeline Avengene (about April 722), the spirit screamed (in Brianna's mind) and then fell silent. Afterward, and for some time, the spirit appeared to be dead or quiescent, partly activated by lust but with no intentional actions.
