First appearing to the party as an undead agent of Gredegaz, she followed you into the portal to the past in an attempt to spread the bone worms and kill Dralta before she had a chance to shutter magic from the world. An undead, rotted corpse, she wielded horrifying magic that nearly kickstarted the plague off early.
After stopping her at the High Temple to Perdita, she then fled outside the city to a clan of druids, where, temporarily broken from Gredegaz's control, she simply wished to be around her kin once more. The illusion didn't last however, as Gredegaz took complete control and turned her form into a shadow of his avatar, an undead dragon that was swiftly stopped by the party before it could wipe out the druid clan.
Faye was killed in the fight, but thanks to the impressive magic of Dara and aid from the party, she lives once again. She told the party of her past, of how her clan was taken by the devils, and how her sister sacrificed herself so she could escape.
She mentioned her clan had been working on a way to live safely from the plague, but it was incomplete, and did lead to Faye's demise in Dulshire where she was raised as a pawn of Gredegaz. Now free from his control, she has chosen to travel with the party in search of a new life and new purpose.
