Gwenvere

A nymph who has since turned into something horrendous, perhaps due to an unfulfilled, jealous love for Anyariel. Anyariel's heart was only for the dryad Timbre. She occasionally emerges for small, meaty sacrifices.
After offering a small rabbit, Jack launched a Faerie fire spell, triggering combat. During this combat, Gwenvere was slain and her head removed by Rayland.
In her cave, Rayland and Winry Mountain Peak discovered a magical trap protecting Anyariel's lock of hair. They outsmarted the trap, and got the lock without harm coming to them.
Jack got the final blows on Gwenvere, continuing to attack after she had expired.
