>>47509163A being born parallel to time and space, ruled over antimatter. In its rage, it rampaged across the earth, devastating it. The Creator God banished it forever. It is to live in a parallel dimension called Distortion World. An eternally dark dimension where light doesn't shine, time doesn't flow, and space becomes distorted.
Thousands of years past, and Giratina lived alone, always gazing into the earth from the mirrorred dimension. A ripple formed a rift between two worlds.
Wary that it might release the underworld monster, the ancestors of Sinnoh people built a shrine to seal the rift. The monster can come out no further than a few feet before the seal open and caused it so much pain that it has no other option than to retreat back into the darkness.
