Key of Memories

'I...I've been having these weird thoughts lately...' His own voice rang through his head...when had he said that? He didn't remember...he couldn't remember anything. His name...what was his name? His voice again came out of the darkness, 'Like...is any of this for real...or not?'

Is this real? Sora...Harry...who are they? He simply closed his eyes, wondering. A calm feeling swept over him, and a sigh escaped his lips.

His feet hit soft land and his large bright green eyes snapped open. Home, was the only thought that came to him. The island. Destiny Islands! The place where he grew up! But...how did he get here? He looked around and his eyes caught site of a silver haired teen standing in the ocean, staring off into the endless blue.
Riku! His best friend! A flash of a red haired boy swept through his mind(Ron...) but he ignored it. To focused on Riku.

He grinned and stepped forward, then noticed the water was drawing up in a giant wave. Riku seemed to notice him and turned around. A smile playing on his handsome face. He held out his hand in a gesture to follow him. But the wave was growing bigger.

'Riku!' He tried to call but nothing came out. He had to warn him! Riku could get hurt! Panicked, he began running toward him. Riku only continued smiling, either knowing the wave was there and ignoring it or not paying any attention to it.

He had almost got to him when the wave crashed down around them. He gritted his teeth, fighting back the currents. Riku only stood there, the waves had not moved him one bit. The currents pushed him even further back from him. Then he could no longer see Riku and he was once again swimming in darkness.
But just as suddenly as the wave swept him, he found himself surfacing again. The sky was a pinkish coloring and the waves were hitting him softly.

'Harry! Sora!'

He turned around and saw his other best friend, Kairi, standing on the beach waving toward him. He once again ignored the flash of frizzy haired brunette girl in his mind(Hermione...) and waded toward Kairi.

Once he had got himself onto land, he put his hands on his knees, panting. Kairi giggled and he smiled at her. Her eyes suddenly went upward and widened. He turned to see what she had looked at.

Two bodies were falling from the sky. One of them was a messy black haired boy with bright green eyes. He had black robes on and looked quite skinny from his view.

The other person was a spiky cinammon haired teen with sky blue eyes. He had a red shirt and red pants on, covered with a blue and white small jacket with chains and necklaces on.

Both boys suddenly entwined with each other, creating a handsome boy with black hair and green eyes with the same face. A perfect mixture of them both.

They collided with him and he fell backward. He distantly heard Kairi's calls for him, but could not answer her. He was once again swimming in the darkness.

Suddenly his feet gently landed on solid ground. He seemed to be in a dark room. There was no light anywhere. He took a few steps forward and light exploded from underneath his feet. The darkness suddenly turned into a flutter of doves that circled around him. He watched, fascinated by them. A few feathers landed on his shoulder but another step blew them off. He looked at the ground and saw a picture of a pretty woman with short black hair, holding a dove in one hand. In circles around here, there was seven small men. Who were they?

He looked around and jumped when a voice suddenly began speaking, 'So much to do, so little time...Take your time. Don't be afraid. The door is still shut. Not step forward. Can you do it?'

Of course he could do it! He took a few steps forward on the glass and suddenly three stones appeared with different items on them. A sword, a shield, and a staff. He looked at each of them.

The mysterious voice said again, 'If you give it form...It will give you strength. Choose well.'

He walked to each one of them, as he walked toward the staff, he stopped and stared at it.

Magic...

A flash of a large castle and a lake appeared in his mind. He took a deep breath and grabbed the staff.

'The power of the mystic. Inner strength. A power of wonder and ruin. Is this the power you seek?'

He nodded, "Yes."

The voice seemed to nodd, 'Your path is set.'

The staff disappeared from his arms. He turned to face the other two. 'Now, what will you give up in exchange?'

The shield was to protect others. He wanted to protect people. The sword was to destroy...he didn't really want to kill unless he had to. So he choosed the sword.

'The power of the warrior. Invincible courage. A sword of terrible destruction. You give up this power?'

"Yes."

'You've chosen the power of the mystic. You've given up the power of the warrior. Is this the form you choose?'

Thinking about it, he nodded, "Yes."

The stones disappeared and the floor shattered into a million golden pieces. He began falling down and landed on another circular foor with a portait of a beautiful woman with a long white dress on. The staff appeared in his hands.

'You've gained the power to fight.'

He slashed out with the staff.

'All right! You've got it. Use this power to protect yourself and others.'

Suddenly, small little black creatures with claws and yellow eyes appeared. He stared at them, they stared back.

The voice didn't seemed panicked, 'There will be times you have to fight. Keep your light burning strong.'

Fight? He looked at them. They suddenly growled and began to try and slash him. He immediately began hitting them with his staff. When one died, the rest disappeared.

'Behind you!'

Turning around quickly, he began to fight them. As soon as he was finished more directions were given to him. He followed each one until he appeared back on the island.

Home.

He smiled and let the breeze caress him, the voice called out softly, 'Hold on. The door won't open just yet. First, tell me more about yourself.'

He walked to Tidus. Tidus grinned at him and asked, "What are you afraid of"
He considered the options laid out to him.

"Being different." He answered, truthfully.

Tidus shrugged, "Bein' different? Is that really so scary"
He didn't answer but walked over to Wakka. Wakka, who had been leaning on the wall, straightened and looked at him.

"What do you want outta life?"

Biting his bottom lip, he thought then anwered, "To broaden my horizons"
Wakka nodded, "To broaden your horizons, huh?"

He shrugged and smiled, before walking over to Selphie. She giggled at him, eyeing him up and down. "What's most important to you?"

Without a second thought, he answered, "Friendship."

She stared at him with a small frown, "Is friendship such a big deal"
He shot her a mysterious grin, that made her blush.

The mysterious voice stated, 'You're afraid of being different. You want to broaden your horizons. You want friendship. You adventure begins at midday. Keep a steady pace and you'll come through just fine.'

He nodded, "Sounds good."

'The day you will open the door is both far off and very near.'

Suddenly, he appeared in a another circular room with a picture of a pretty blonde woman with a rose in her hand and thorns surrounding her. Shadows appeared and he drew his staff and killed them.

A light appeared to the side, and when he glanced over there he saw a long flight of stairs had appeared. He began to run up them until he appeared onto another circular floor.

He saw a light in the middle of the room, thinking it was a good sign, he began to walk toward it.

But the mysterious voice called out in a warning, 'The closer you get to light, the greater your shadow becomes.'

Swallowing hard, he slowly turned around and saw that he shadow, had indeed, grown long. It seemed to take life and grow larger until it grew into a smirking black mass. 'The Darkside', something whispered in his mind.

'But don't be afraid. And don't forget...' The mysterious voice said in a soothing voice.

Screw it, he started to run to where the stairs were, only to find them gone. He staggered to regain his balance, from nearly falling. Breathing hard, he turned to face the darkside. It grinned at him. He growled and drew his staff, locking onto one of its giant hands, he began to hack at it.

He ignored the other small shadows, surrounding him, to busy trying to get rid of the darkside.

Big mistake.

One gathered up enough courage to slash at him. He cried out in pain as a gash appeared on his leg. He killed the small shadows and turned back to the large one, once again slashing at him.

Minutes later, he stood back and watched as the Darkside finally slumped in defeat. Triumph went through him, as he reached for a potion to heal his wounds. Before he could, a black circle appeared underneath him.

He tried to escape but it held onto him. The voice made a appearance one last time.

'But don't be afraid. Both of you held powerful weapons. And now combined into one. You hold the mightiest weapon of all.'

Before darkness could take him, he heard the voice once more, 'So don't forget : Now combined into both Harry and Sora, you are the one who will open the door.'

Sora jumped up awakening at last on his home, panting. "What the-?" He muttered.

He heard a noise and turned to see Kairi standing there. He jumped in surprise, "Whoa!"

She giggled.

He smiled, "Gimme a break, Kairi"
She smirked at him, "Sora, you lazy bum. I knew that I'd find you snoozing down here."

He remembered his dream, "No! This huge black THING swallowed me up! I couldn't breath, I couldn't-Ow!" He clutched his head as a sharp pain went through.

She shot him a look, "Are you still dreaming?"

He shook his head, "It wasn't a dream!...Or was it? I don't know. What was that place? Who...who is Harry? So bizarre..."

Kairi only rolled her eyes, "Harry is probably your boyfriend or something."

"No! He...he...I don't know..." In a whisper, so Kairi wouldn't hear, "Is Harry...me? That's what he said..." He looked up at Kairi, a sudden question in his head.

"Say, Kairi, what was your hometown like?"

"Harry! Where are you?" Hermione called, frustrated with her best friend. Ron looked into another empty classroom, "Not in here either, Hermione."

"Oooh! Where could he be!" She asked, worried. Ron shook his head.

"I wish we still had the Maruaders Map, then we could atleast see if he is in the castle." Ron stated.

Hermione didn't reply, she had frozen, "What if...what if Sirius Black has gotten him"
Ron looked nervous, "There...there was no sign of struggle in his bed"
She still looked scared, "He could of went for a walk after everyone went to bed and Black could of just...just..kill- snatched him!" She sniffed, unable to say the word 'killed'. A few tears leaked from her eyes at the thought.

Ron shot Hermione a look, "Hermione, I think Harry is smart enough to know not to go out when there is a madman after him."

Hermione glared at him, "He's been missing for over 20 hours! We should tell a teacher."

Ron nodded, "Which one?"

"Well...Dumbledore, maybe."

"Nah, lets just tell Lupin first. He seems to be pretty close to Harry. His office is nearest, anyway." Ron said, already walking to it. Hermione watched him nervously, before following, wringing her hands together nervously.

When they reached it, Ron knocked on the door and a voice answered, "Come in"
He opened the door to see Lupin sitting at his desk, grading papers.
He smiled at them as they say down, "Mister Weasley, Miss Granger. What brings you two here?"

Ron nudged Hermione to answer, she glared at him, "Professor Lupin. Its Harry"
He blinked, "Yes, I noticed he wasn't with you. Is there a problem?"

She nodded, "Yes actually. Professor...we can't find him. Ron looked at his bed this morning and he wasn't there. We haven't seen him since last night."

Lupin froze, "Are...are you sure?"

"Positive. Can you look at that map, you took from Harry?" Ron asked. Hermione stomped his foot, "Ron"
"What!"

Remus nodded, and took the map out, "I solemnly swear that I am up to no good"
Lines appeared on the map, Remus tapped the paper with his wand, "Reveal Harry James Potter."

Hermione gasped, "You can do that?"

Remus nodded, seconds passed and writing appeared on the paper.

/Mr. Prongs is sad to inform that Harry James Potter is no longer at Hogwarts. Departion time at 1:34 AM in the morning/

Ron gaped at the map, "Can it tell us anymore?"

Remus shook his head, "No. Hermione. Ron. Please return to your common rooms. I will contact the Headmaster. If anything happens, I'm sure you two will be informed."

Nodding sadly, they both left. Remus sat there, staring at the map for a few seconds before whispering, "Mischief managed."

He hid it in a drawer and walked to his fireplace, throwing powder into it, he called "Albus Dumbledore!"

Dumbledore's head appeared in the green fire, "Remus! What a pleasant surprise! What can I help you with, today?"

Remus took a deep breath, "Albus...we have a problem."

He was approaching a large castle in boats across a lake. A girl unlocking a door(Hermione?). Flying around a field on a broom. A large snake collapsing on the stone floor. A baby crying as a flash of green light went through the room and woman falling dead...

Sora awoke with a start. He looked around to see if he had awoke Donald or Goofy. No. Still asleep, thankfully. Sora sighed and walked to the mirror, wincing with each step.

They had just gotten back from Atlantica and his legs were still getting used to walking on land. They flew back to Traverse town and Leon and Yuffie were happy to give them a place to stay at the hotel.

Sora glanced at the mirror. His spiky black hair still pointed in different directions. Bright green eyes peered back at him. He had a thin mouth but full lips. His skin was smooth and tan from all those long days at the beach. But not dark dark tan. In his own mind, he thought himself to be normal looking. But whenever he went to a world, heads turned to him.

Yuffie had grinned even more brightly at him. Leon had froze, before their fight, eyeing him up and down. Alice had turned a bright red and turned away, mumbling. Jasmine(during the few moment they were together) had been to close for her own good. Ariel flirted with him. And even though Sora would never admit it...he had a slight crush on Cloud(Who doesn't?)

Kairi...she was a friend...nothing else. (sorry...)

Donald and Goofy never seemed to notice. Thank God.

Sora turned from the mirror, thinking about his dream. What were those image? That girl...the castle...it wasn't the other castle he dreamed about, that castle was something else. He shook his head and looked outside. Dawn.

He had to wake Goofy and Donald up.

"It's been a week, Headmaster, and there is still no sign of him." Severus Snape muttered to Albus Dumbledore.

Dumbledore sighed, "He will appear. I know he will. Though it what condition...I do not know."

Snape stared at him, "How can you be so sure the boy is still alive! With Black after him-"

"He is alive."

Snape opened his mouth to question how he would know, when the door banged open and Minerva McGonagall stumbled in.

"Albus! Harry Potter just appeared in the Great Hall!"

Snape's eyes widened. Dumbledore stood up and swept from his office. The other teachers followed him until they reached the Hall.

Dumbledore entered the room to see a circle of students, talking, surrounding a body.

"Students! Please return to your common rooms!"

There was protest, but they did as he said. Ron and Hermione ran up the Dumbledore.

"Professor, can we-"

"You two, also."

They reluctantly left. All that was left in the Great Hall were the teachers and a unconscious Harry Potter also known somewhere far away as Sora.

Dumbledore approached him and took in his form. His hair was longer and spikier. He had a red shirt and pants on with a small blue and white jacket on. He had a necklace with a crown on it. There were chains holding up his pants. But what really drew his attention was the large key in his hand.

It was black and sharp. A chain hang down in the same form of the crown on his necklace.(sorry I haven't gotten the Ultima one yet.)

Oblivion.

Dumbledore touched it, only to draw his hand back, burned. "That is a powerful weapon that had kill many."

The teachers gasped at the thought of the boy-who-lived killing anything. Dumbledore summoned a stretcher and placed Harry on it. They began walking to the Hospital Wing. The Keyblade hung from Harry's hand.
