Xenoblade takes place on two massive Gods that, long ago, fought in battle that resulted in two dead corpses, frozen and locked together by their swords. The entire film takes place on these two Gods that have been frozen in place. Bionis developed life on its body over time, while Mechonis became overran by machinery. The machinery has since started to invade Bionis and destroy the colonies there. Only a sword called the Monado can cut through the armor of the machinery, and is said to be the sword of the Bionis itself.
