Gerald is the boss of Firefly Forest. As all other bosses, his level and health are unknown, and he does massive damage when awakened. He is battled through using a Magical Flute, obtained also during a quest in the Firefly Forest.
He appears to have rocky skin with bushes as shoulder and body coverings.
"A Sleeping Golem, Boss of Firefly Forest. Awaken with care...he DOES glare."
