A Graduul is Demon terms for 'Berserker'. They are particulary violent once someone is in their territory. They mark their territory by making a giant rock pile. Graduul feed from the Fire Trees, where they consume the burning chemicals, hence Fire Trees. They don't have tongues, so that they don't burn themselves from the liquid of the Tree. Their forms of attack include their charge, where they reach speeds of 200mph. They also use their giant fists, and they jump at heights of over 30ft.
