She is the first World Eater that Revya and Danette come across. Feinne is the most powerful World Eater in Haephnes, as well as being the most inactive. Gig describes her as his favorite World Eater of the three. Before becoming a World Eater, she was once a Haephnes god known as Resilience, who knew Gig back when he was Vigilance. Feinne is one of the primary (though inactive) threats early on in the game due to her being the only World Eaters whose location is known as well as being drastically close to Raide, so much so that it was able to wipe out half of the kingdom in one blast. In the Demon Campaign, she battle the Main Character only to be defeated, but still alive. In the final battle, she seems to have reformed to the side of good along with Raksha, who asks to eat a part of her soul in order to battle the Main Character, since she cannot. In the "Good" Demon ending, she and Raksha intend to reincarnate and restart their life cycles with the help of Gig, who has regained his memories of his past life as Vigilance the Master of Death.
