From the back of the box:
In a dark time, an epic adventure dawns...
Evil is slowly covering the world. Forces of darkness are pursuing the lost art of Alchemy, and as they draw ever closer to their foul purpose, mankind hangs in the balance. You and your companions are the last hope: armed with noble weapons, magical Psynergy, and a host of elemental creatures, you must find a way to stem the evil tide.
An enormous RPG shines on the Game Boy Advance! With incredible graphics, an engrossing story line, and a huge world to explore, you'll be playing long after the sun sets.
Unbelievable magic! Gather the four types of elemental creatures--fire, water, wind, and earth--and combine them in different ways for some of the most awe-inspiring magical spells ever seen.
