Prologue: The Sinner
Thousands of worlds exist. This is not a wild guess, but fact. The only reason worlds remain hidden from each other is that they've never been connected. Every now and again, barriers separating the worlds collapse, and the worlds become conjoined. This happens to a select few worlds- not all worlds are connected at any one time.
Some worlds are guarded by barriers so strong, they've never been connected. And for good reason, for some worlds are so horrific, if they were ever connected to the others, all Hell would break loose...
A man walks down a cobblestone street- it is raining. Icy, sterile drops of water fall upon the city, a city that stretches for miles in every direction. The man lives in this city. He passes a homeless man on a street corner, and drops a silver coin into the tin cup the homeless man holds.
With a metallic –clunk!- the man smiles down. "God be with ye, child," he says. The homeless man flashes his generous benefactor a toothless grin, and he goes to spend the coin on a knife that he will kill a prostitute with this night.
And the charitable man walks in the rain. His name is Reverend Virgil Elysium Morningstar, a descendant of an angel. He is a priest in one of many cathedrals that haunt this city. He is a priest, one destined to wield a Keyblade. He is a priest, but above all, he is a sinner.
