Forward Yes. This is a prequel to Kingdom Hearts, set in the Hollow Bastion, 10-9 years before the game begins, between Ansem reports three and four. How many times has this been done? I'm not sure. I'm not sure what even inspired me to start writing this. The only thing you should know, is that it starts slow, but it gets better, I promise! I hope you enjoy reading this, as much as I enjoyed writing it. So, without further ado, here is Enter Oblivion.

Part I: As Light Fades

Prologue: He

"Ones born of the heart and darkness, devoid of hearts, ravage all worlds and bring desolation. Seize all hearts and consummate the great heart. All hearts to be one, one heart to encompass all. Realize the destiny: the realm of Kingdom Hearts. The great darkness sealed within the great heart. Progeny of darkness, come back to the eternal darkness. For the heart of light shall unseal the path. Seven hearts, one Keyhole, one key to the door. The door of darkness tied by two keys. The door of darkness to seal the light. None shall pass but shadows, returning to the darkness. Ones born of the heart and darkness, hunger for every heart until the dark door opens."
-Kingdom Hearts, End of the World Computer

Aerith had lived in the grand castle all her life. She knew almost everybody, being very popular within the fortress, and only at the tender age of fifteen. She knew everyone, even the king, Ansem, who knew her on a first-name basis.

There was someone, though, whom she feared for her life for. Why though? What was it about him? Aerith could feel evil haunting him like a corpse, an unholy specter. He was shrouded in mystery, and it scared her.

His name was deceiving. It made one think he was a "shiny happy person", and though he was mysterious, most thought him to be harmless. All except for Aerith. Perhaps it was his name that made her suspicious. As mentioned before she didn't know. His name... how it inspired a foreboding feeling of despair and pain into her heart...
