Hey y'all! I've been getting addicted to Kingdom Hearts again, so I decided to create this crossover! It has the House of Anubis characters, but follows the plot of Kingdom Hearts. While you're reading, see if you can tell which character is which by what I've given you!

So, the prologue is basically the main character's Dive to the Heart. It's long, I know, but I wanted to get this part over with. I hope y'all like this story! :)

DISCLAIMER: I don't own House of Anubis or Kingdom Hearts. The words in bolded italics are lines I added to the story from the game, not from me.

I've been having these weird thoughts lately... like is any of this for real... or not?

A barely conscious brown-haired boy sinks further into the endless blue surrounding him. He doesn't know how he got there exactly, but he's too out of it to care.

With a sudden burst of light, the boy awakens on the beach of his beloved island. The sun stings his eyes as they adjust to the light, and he looks around for his friends that are usually here. He spots his best friend, a tall, skinny, blonde boy, in the ocean ahead of him and goes to join him, but the ocean begins to recede before he can do so. The blonde boy turns just as a huge wave begins to rise behind him, and holds out his hand as an invitation. The boy on the beach, worried because the wave is about to fall, runs forward. The wave, however, finally falls and knocks both boys underwater.

After tumbling around for a bit, the boy opens his eyes to see the blonde boy holding his hand out again. And again he tries to grab it, but the current pulls him back to the surface.

Breaking through the water's surface, the boy looks around for his friend, but doesn't find him. Instead, he finds his other best friend, a girl with dirty blonde hair, calling to him from the shore. He sloshes up to her and smiles as he tries to regain his breath. Giggling, she smiles back, but turns her attention to the sky and watchs as meteors begin to fall from above. The boy turns and watchs with her, but notices a figure that looks strangely like him. As the figure makes contact with the ocean, he begins to feel faint and falls back into the water.

He sinks just like before, but instead of feeling the water, he feels air. The girl above him tries to grab his hand, but misses and watches as he falls through the sky.

He breaks through the water again, but is conscious this time as he sinks into the dark ocean. Landing on a dark platform of sorts, he looks around, only to be greeted by darkness. Stepping forward, he shields his eyes as hundreds of doves erupt from the platform and reveal a green mosaic of a sleeping girl holding an apple.

So much to do, so little time...

"Who said that?" he calls. It's futile, however, seeing as how the only thing around him is the platform and darkness.

Take your time. Don't be afraid. The door is still shut. Now step forward. Can you do it?

Still startled by the voice, he tentatively steps forward a few paces. Three pedestals emerge from the platform with an object on each of them.

Power sleeps within you.

The first pedestal holds a black shield with a red border on it. In its center is a strange emblem; it looks to be three circles joined together.

If you give it form...

The second pedestal contains a green staff with the emblem on top of it. Only this time, the symbol is blue.

It will give you strength.

The last pedestal in front of him holds a silver sword with a gold and blue hilt. On the gold sits a red circle, and in its center is the emblem in black.

Choose well.

He looks at the items around him and thinks about their benefits and disadvantages. The sword, however, seems to call to him, and he reaches forth to grab it.

The power of the warrior. Invincible courage. A sword of terrible destruction. Is this the power you seek?

The boy chooses the sword as it vanishes into thin air, leaving only the shield and the staff behind.

Your path is set. Now, what will you give up in exchange?

The boy walks towards the shield, feeling that he wouldn't need its powers as much as the staff, and lifts it from the pedestal.

The power of the guardian. Kindness to aid friends. A shield to repel all. You give up this power?

Again, the boy chooses to give up the shield as it vanishes.

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

The young boy agrees and the pedestals disppear. However, the platform shatters into millions of fragments as he plummets down through the darkness.

Looking down as he falls, he sees a purple platform with a mosaic of a sleeping girl in blue with stairs behind her. As he landed, the sword he had chosen appeared in his hand, and the voice spoke again.

You've gained the power to fight. Use this power to protect yourself and others. There will be times you have to fight. Keep your light burning strong.

Three small, black creatures emerge from the ground and stalk towards him. Their beady yellow eyes and sharp claws tell him that they are enemies, and he slashes through them with his sword. The creatures burst into shadows as the boy defeats the final enemy.

Behind you!

The boy turns to see that the shadowy creatures have crept up behind his back. He quickly defeats them, again. The last shadow, however, seeps into a black puddle which slowly begins to consume the entire platform. The boy sinks through the darkness, reaching for anything to pull him out.

He thrashes as he feels the darkness disappear, and he finds that he has ended up on a pink platform. The mosaic contains three blue silhouettes in hearts. As he stands, he spots a door on the opposite side of the platform. The door, however, is transparent and he can't open it.

Suddenly, a treasure chest appears behind him, but it contains nothing when he opens it. A box appears behind him as well, and he smashes it. The box, unlike the chest, contains a small bottle of what looks to be a potion.

The door's border becomes opaque as a barrel appears from behind him, yet again. He lifts and throws the barrel as the doors becomes fully opaque. Opening them, a gleaming white light streams through them and consume his vision.

Hold on. The door won't open just yet. First, tell me more about yourself.

The boy hears the voice as he appears on his home island again. Three of his friends, Selphie,Tidus, and Wakka, sit around him. He talks to each of them, telling them that friendship is what's important to him, he's scared of being different, and that he wants to broaden his horizons.

Friendship is important. You're afraid of being different. You want to broaden your horizons. Your adventure begins at dawn. As long as the sun is shining, your journey should be a pleasant one.

The boy nods and starts to walk away, but stops as the voice talks again.

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

The boy ends up on an orange platform with a mosaic of a sleeping girl in purple holding a rose. The shadows appear around him again, but he destroys them just as fast as they came. As the shadows disappear, a flight of colorful steps materialize and lead the way to the next platform.

At least I won't fall again, the boy thought.

This new platform was yellow with another mosaic of a sleeping girl dressed in yellow with a menacing beast behind her. The voice startled the boy from his thoughts as it spoke again.

The closer you get to light, the greater your shadow becomes.

The boy looks behind him as his tall shadow comes to life. He stumbles back in fear as the shadow takes the form of a hideous beast, with huge limbs and beady yellow eyes. Its face is covered with dark vines and it stands at least five stories high.

But don't be afraid. And don't forget...

Forget what? He thinks as the beast swipes at him. The large monster's hand slams into the ground as a pool of darkness swarms from it, generating the small shadows again as well. He slashes them, as well as the hand, and the monster rears his hand back from the hits. He keeps slashing at the hands as small purple orbs from the beast's chest pelt him. With one final hit, the monster rears his hands back and roars.

HIs sword disappears in a sparkle of light as the beast lunges forward. The boy begins to sink into the darkness again while the monster stares at him with its piercing yellow eyes.

-But don't be afraid. You hold the mightiest weapon of all. So don't forget:

The boy sinks fully into the darkness that pulls him through the floor.

You are the one who shall open the door.

Review? :)
