The Olympia and all who know them

The Shinobi world was full of secrets, secrets that could destroy nations.
But there were some secrets that even Shinobi didn't know, secrets that had to be revealed by a very particular kind of being.
Several humans had learned the secret, sworn to take it to their grave.
Some were humans the beings had taken a liking to, granting them and their descendants' abilities beyond the norm.
Some were great leaders, prophesied to bring a great change in the land, and some were humble, a human who noticed their friend was more than they seemed, a lonely child, who found a lonely parent.
But the humans who knew were few and far between.
One to know was a man by the name of Hashirama Senju, a man who brought peace to the continent and tamed the nine godlings and created the Hidden Village system.
Another a little girl, her city in ruins around her, who looked up to see a bright smile and a brighter future.
And yet another was only a decade or so ago, a man who accidentally transported himself into a being's home, and was only able to leave due to the being's sense of humor and their own history of bad luck.
Those beings were gods, remnants of an old-world, and protectors of the current one. As long as nothing world-ending came about, they were content to just watch, give a helpful or harmful hand or simply walk among those who lived in the blink of an eye, acting in a play only they could see.
But sometimes, they gave more then just a nudge in the right direction.
Sometimes, they said "Enough is enough. Leave him be." And the world changed in the wake of teir actions.
This is the story of one such time, that ushered in a new era with nothing more then a kind word and a promise.
