Prologue
The Norse gods were assembled in the halls of Asgard. They were conversing politely though they were obviously having disagreements. Suddenly a light flashed in the center of the room. The various gods looked toward the light, startled that someone would be flashing in. Where the light once was, three old ladies stood.
Odin looked towards them, puzzled. "The Fates. Are you not, in fact, Greek? What business do you have here in Asgard?" The Fates smiled at the assembled beings.
"There will come a time when the eras of all the gods will be put in peril by an enemy so old their name is forgotten to all but a few. Only one person will be able to save you. They will have the heart of a hero and the power of gods. He will be your only chance at survival." The Fates looked on solemnly at the stunned gods.
Thor recovered first. "Why do you tell this to us? Why not your own gods? Surely they deserve to be warned too." The Fates nodded before giving matching grins.
"We are telling the other gods. Who says we can only be in one place at a time? We are currently in the presence of all the other gods as well as yours. We tell you this because the hero will bind together, and save, all the gods and not just the Greek ones. With our warning delivered, we must go, for we are no longer allowed to directly meddle. Farewell Asgardians and good luck."
With their message delivered, they flashed out of the rooms of each culture's gods, leaving behind stunned beings. Over the years, memory of the prophecy slowly faded. Five thousand years later, the prophecy is all but forgotten. However the prophecy never disappeared despite being forgotten. It would still come to pass, whether it was remembered or not. And pass it would, turning the entire world upside down.
