Shattered Hearts: a KH fan-fic

The sun rose on a once lush and beautiful world, but now the once large green forests and beautiful, flower filled meadows were now dry, dusty deserts and large sun scorched mesas. This world had once been the most beautiful of all and now what had once been called Phoenix Mesa was now a barren place of death and dust.
The sun harsh light burned on her face as she awoke, her large deep purple eyes squinted as the harsh brilliance of the sun burned them. Slowly she stood up and looked at her surroundings, her long grey hair falling down her back and tickled her thighs. Slowly she dusted off her dusty tan pants and matching "shawl", and tightened the brownish tan bandages around her torso, and feet.
"Who am I, and what is this place?" she whispered as she turned around again observing the dead landscape around her. Movement caught her eye as 5 Heartless moved toward her. Her eyes widened as she saw these creatures, and as the familiar sensation of her Keyblade coming to her aid.
The odd blade flashed once as all 5 Heartless were felled. Sighing she put her Keyblade away and walked toward and small village of tents. The smells that came to her seemed familiar but distant as if much of her memory had been erased.
The village bustled with people and animals, as the markets sang with the voices of competing merchants trying to sell their goods. A scream rose from the crowd as someone, a woman, saw her.
"It's Grey Phantom!" the woman shrieked hysterically pointing at her as others started to stare. Several women fainted as three men started hurling stones at her. She had to get away, but there was nowhere else to go. She closed her large, deep purple eyes. More screams sounded as a large corridor opened. It looked as if something just shattered a large hole between worlds, as if a mirror had shattered and lost several pieces from its center. Not knowing what to do the girl ran into the corridor as it closed off from that world and opened to a dark alley in the next. Slowly she walked into the alley as the words of the woman rang in her head.  
"So I guess that's my name", she said out loud to no one in particular, "So I'm Grey Phantom." And with that Grey Phantom stepped out of the alley into the streets of Twilight Town.
