Before Pokemon, before shinobi, before humanity had even pulled itself out of the muck, there were the Legendaries.
They guard rivers and forests, hold dominion over sea and sky and ground, control time and space, even bring life and death to all who dwell upon the earth.
Sovereign over these multitudes is Arceus, creator of all, a god among Pokemon and humans alike.
It was he who brought about Pokemon, who helped humanity rise to supremacy, who watched as the Jubi was separated into nine Bijuu and sealed away.
When the humans banded together and raised villages of shinobi, it was Arceus that offered an alliance between humanity and Pokemon, and who built a bridge between the two.
Someone who could Speak and Connect with Pokemon, who could see into the hearts of ninja and create Bonds between them and a chosen partner…
And so the Oracle was born.
