Summary:

It is the finale of an invisible war; most of the legendary Pokemon, Guardians of their world, have fallen, and dark forces threaten to swallow this world, and only Arceus and a small honor guard remain, remnants of something once great and powerful.
In these final moments of light, they form a desperate plan, a plan that hinges on the light crafted into a female, and the darkness gifted to a male.
A male that happens to be a human. A human on a strange world known as Earth. Our Earth.
