The Beast is said to be able to take many forms - floods that meet the sky, fires that water cannot extinguish, monstrosities that slither and soar. The Wizard stopped the Beast before with the use of Eternal Warriors, who formed a wall along the Emerald City to keep the Beast Forever from flooding entire world.
