Plot Summary
The Planet R has been kept in balance through four magical crystals, each one representing one of the physical elements: Wind, Water, Fire, and Earth. 150 years ago, the balance was upset, and the Crystals shattered, releasing a dread force of nothingness. The shattered crystals chose four heroes, and these four would face and eventually defeat the cause of the evil, returning the world to tranquility.

Now, the Crystals are in danger once again, and descendants of those great heroes of the past must rise to the call and ensure the safety of planet R once again.

Final Fantasy: Legend of the Crystals is based on the fifth installment of Square's highly popular Final Fantasy series. 200 years after Batz and his friends saved two worlds from the threat of Ex-Death, a threat arises and seeks to take the Crystals for itself. Linaly, a descendant of Batz, and her friend/protector Pretz journey to the Temple Of Wind to seek the source of this new danger.
