Xenoblade Chronicles takes place on the frozen bodies of two warring titans, the Bionis and the Mechonis. The people of Bionis, including the human-like Homs, are in a perpetual war with the Mechon machine race of Mechonis. Key to the Homs' efforts in fighting the Mechon army is the Monado, a sword said to have been wielded by the Bionis. (Wikipedia)
