Gildie is a female flareadon that lives at Havenfield. She is eagle-sized with gold fur and eyes. When Gildie first arrived at Havenfield in Keeper book 1, Grady and Edaline thought she was a pterodactyl until Sophie read her mind telepathically and realized Gildie needed fire to survive as a flareadon. It was speculated later that the Black Swan sent Gildie to Sophie on purpose so that she could collect the everblaze that was burning in the Forbidden Cities.
Sophie was given a gold flareadon Prattles pin by the Black Swan as a clue to use Gildie to catch the Everblaze.
