Gaiazor is a massive quadrupedal rock monster who is one of the 8 Elemental Titans where it is the Elemental Titan of Earth. It was put to sleep in Brightoak by the Elemental Avatars on the continent of Drakonus. Many years later, the Queen of Monsters took control of Nevanna in order to awaken Gaiazor from within the heart of the World Tree using the Celestian Horn of Balance. Despite defeating Gaiazor, it fully emerged as Nevanna started to use it to cause destruction throughout Brightoak.
