During a wartime period long ago, there existed seven elemental Power
Stones each emitting unique colors, used to take control of the world.
Many Ninja’s acted behind the scenes during the war; high trained in
both body and mind. These skillful ninjas would use these Power Stones
to end the war.
Before long, the chaos would end and peace comes to the world again.
And these Power Stones would now be referred to as GEMs, which have been
seperated in 7 stones and sealed away.
