Final Fantasy III
The game is set in the floating continent, and puts players in control of four orphans raised by an elder named Topopa in the village of Ur. After an earthquake opens up a hidden cavern in the Altar Cave just outside of their village, the orphans set out to explore what lies within. What they find is a crystal of light which grants them each a portion of its power and instructs them to restore balance to the world.
In the past when the Light was threatening to overtake the world 4 Dark Warriors emerged and cut a swath of destruction. In the present these characters now work for the Light, hopefully to once again restore balance to a world now threatened by the Xande and the Cloud of Darkness--a nihilistic mastermind behind the world’s descent, and the game’s ultimate foe.
