The Sixth Element

He has returned. The one who they have all feared for millenniums, who is said to doom the entire world to an eternity of darkness and death, has risen from his cage. After millions of years, the peace between the Kingdoms of the world is breached as their worst fear comes true. Darkness has overcome the world, promising destruction to fall upon the innocent civilians of Earth. The Elemental Masters, the four most powerful benders in existence, unite to do all they can to save their Kingdom from the doom that threatens to overcome their land. But the fifth element is missing, and an unlikely hero is discovered.
