A/N: I'm not abandoning Cloudy Day, Stormy Night. At all. Trust me. This is another, new fic. I wrote it on Air France flight 1050, actually. Enjoy!

Thanks to my lovely, beautiful, nice, sisterly, amazing, and incredibly inspiring beta and adopted sibling, xkidrogue. Thanks, I couldn't have done it without you.

Prologue: Darken

Prophecy, Book 1, Prologue

When the stars fade away,

When darkness falls,

The sun shall set forevermore.

Unless...

A chill wind blew across the sandy beach, uncharacteristic of the Destiny Islands. Sand blew in rivers, gliding over the beach below before gracefully dropping into the sea. The light of the setting sun cast a twilight glow over the entire scene.

It is quiet. It is about to happen.

A cloaked figure stood, looking out on th endless sea, his dark robes fluttering in the wind like so many shadows. In his arms lay two babies, fast asleep. One had eyes of pure aquamarine and hair like silver fire. The other had deep cerulean eyes, reminiscent of the sky, and dark brown hair. The brunet shifted in his deep sleep. A small smile was brought to their guardian's face as he lay a pale hand on the infant's forehead.

Sleep, little one. Night will fall soon.

The pale orange of the sun slipped below the horizon, throwing the palm trees and tropical plants into near darkness. Shifting slightly, the cloaked figure set the silver-haired baby down.

Riku.

He extended his shrouded hand towards the sea, and made a motion as if to grab something. A brilliant flash of white light surrounded his fingers, causing them to glow brightly. A warm wind began to blow, causing the cloak to flow like water around him, and causing the spiky hair of the young baby to bob.

And then it was over, the white light departed. In it's place stood an enormous key, gilded with gold and silver.

Keyblade.

In one swift movement, the guardian picked up Riku and swung the keyblade. In it's wake, a gleaming door of light began to form. Small motes of light twirled through the air before meeting to create a doorway. Hesitating for a moment, the cloaked figure looked around, almost regretfully. Then he tightened his hold on the two infants and confidently walked through.

Doorway.

Abruptly, the glowing door vanished, and complete darkness took the islands once more. And high above, hundreds of doors began to open. Yet these were not the shining, bright doors of the Light. Instead, these were dark, curving, shadowy doors. These doors released only utter darkness. A wave of shadow swept across the tropical paradise, stifling the light, bringing night forevermore.
