Final Fantasy: Mystic Quest

The Focustower is the center of the world and keeps the forces of the world in balance. But 4 monsters have stolen the 4 elemental crystals (earth, water, fire, wind) for their own use and have also taken the 4 keys for the doors inside the Focustower. The balance is disturbed and the world is beset by disasters. A young boy named Benjamin finds his home village destroyed. When he meets a mysterious old man while fleeing the earthquakes, he soon learns that he is the prophesied hero and the only one who can save the world. Benjamin must recover the 4 crystals, unlock the focus tower, and defeat the ultimate monster before the fifth crystal, the Crystal of Life, is damaged.
