Long ago, there was once powerful Pokemon that people called The Blinding One gave light to the world with the help of the beast of the sun and the moon. Still, the blinding one fell into the darkness that caused most destruction to the world, so the ancient sealed the blinding one in a prism that a chosen hero will one day restore the light to this world.

Giratina is one of Arceus's children; he lives banished to the reversal world for its uncontrollable powers. Still, it had a mirror to see all other dimensional worlds called the dragon mirror-like its brother Palkia, so it cast out the mirror so Arceus wouldn't destroy it. Still, it drains some of Giratina's power, so it waits for some of its strength back and connects to mirror
