The Olympians lived among people once. Each from in one of the nine dimensions, all in which are lost and forgotten. However, with such power, came the seven deadly sins; greed, lust, anger, gluttony, wrath, despair and sloth.
The Knights became corrupted, where children grew older and lost their innocence. The most loyal of allies, became the greatest of foes. The realm of the dead reigned in anarchy, chaos spreading to life of the living. Those with power became tyrannical, causing war and destruction. Even the lord of the sky gave up supreme power for a selfish wish.
They fell one by one, deciding to die than live chained to their damning sins. To live among humanity and to live a life on earth would erase the sins of the Knights.
