It was 11:30, and Percy was in combat training with Annabeth. Percy was so close. So close to beating her. But just when he had the chance, he stopped. There was an unfamiliar noise, like a bell. Percy snapped out of his daze, to realize that he was not the only that was hearing this. Annabeth's face dropped. As she sprinted to the dining pavilion.

"Annabeth! Wait!" Percy yelled, running after her. As they entered the dining pavilion, Chiron was awaiting them. "Annabeth, what is going on?" Percy demanded.

"You haven't been here long enough to know." Annabeth whispered. "It's only gone off one, and it wasn't good." Annabeth was the bravest person Percy knew. If she is afraid, it must be really bad. A few people looked just as confused as Percy did, but the majority of the Demigods were silent, too terrified to speak. Chiron stood; ready to announce what all the fuss was about, as the last of the Demigods filed in.

"Demigods, as many of you know, this is a time of fear. I have selected a handful of Demigods to fulfill this quest." Chiron began. A few people looked confused. This is it? I've been on quests before, Percy thought. But judging by the look of fear on Annabeth's face, there was more to it.

"This will not be an ordinary quest. As I see it, other experts will join you. I have only chosen the best. So with that, will Annabeth, Clarisse, Percy, and Grover step forward?" The four teens approached Chiron.

"I will let you see the oracle now." Chiron finished. "The rest of you can carry on with your activities." The crowd slowly waked back to their activities.

The room was dusty, and Percy tried hard not to cough. Chiron left them, as they were the only ones to know what the oracle was to say. Grover looked scared, but Clarisse and Annabeth looked determined. Determined to complete the quest.

They stood around the oracle, and it slowly began to talk.

To Manhattan you shall go,

To defeat a metal foe,

The friendships you must keep,

And journey in the deep,

Five more to await your coming,

To end the endless running.

The oracle stopped. The room, silent. No one knew what to say. Partly confused, partly excited, they all shuffled out of the room.

"Well, it looks like we have a long ride ahead of us!" Annabeth said.

"How are we going to get there?" Grover asked.

"I think we should go like we always tend to go." Percy suggested. "Taxi!"

"But a taxi could take a while to come!" Clarisse reminded everyone.

"Right, for the meantime, let's go talk to Chiron."

Chiron was waiting down by the river, skipping stones. When the sound of gravel crunching traveled to his ears, he turned, and waved.

Percy was the first to talk. "Chiron, the oracle said that five more are to await our coming. What exactly does that mean?"

"That is easy. Do you remember when I was talking, and I said that many more experts were going to join you along the way?" Chiron answered. Everyone nodded. "There will be five experts."

"How do we know we can trust them?" Clarisse questioned.

"Although you have never met them, I have met with Dumbledore before." Chiron said.

"Dumbledore? Who's that?" Grover asked.

"The Headmaster of a very good school. A school for people, with unusual talents, like yourselves." Chiron explained. "I would trust Dumbledore with my life."

"Good enough for me." Grover said.

"Chiron, we need to get to Manhattan, which is where we will meet with the experts." Percy pushed.

"And I have asked for a taxi to pick you up. It should come in about ten minutes? Yes, ten minutes." Chiron answered.

"Ok, so what should we do while we wait?" Annabeth sighed, looking very eager to get going.

"Overlook what the oracle said, one more time. You must be prepared to fight a horrid thing, if necessary." Chiron said.

"Everyone, let's talk it over at my cabin." Percy insisted. "I'm the only one, so we don't need to worry about people trying to eavesdrop on us."

The walk to the cabin was silent. As they reached the door, Percy took the handle, and gestured for everyone to walk in, while he held the door. Once everyone was in the room, they began the conversation.

"Ok, so we know that we have to go to Manhattan, and that we will be meeting up with five people, someone named Dumbledore probably, or someone that he mentors." Percy started.

Everyone nodded, and Annabeth followed. "We are going to be fighting something, probably something that we have never seen before. Something from another world?"

Everyone agreed, and then Grover spoke. "And we know that because it said a metal foe. That sounds like it could be a robot or something!"

Eyes looked at Grover, confused. "Well, if they are metal, I can chew on them!" Grover said, excitedly.

Percy sighed, "Grover, they probably won't be very friendly."

"Oh. That's a little less exciting." Grover replied.

Clarisse cleared her throat, "journey in the deep, what do you think that's all about?"

Annabeth opened her mouth to say something, but then closed it. "I have no idea. I guess we will have to wait and see." Percy exclaimed.

"Finally, end the endless running. What are we running for, the creature?" Clarisse asked. "We haven't met the creature yet, so it can't be endless for us."

"Good point. Maybe the other people have been running from this thing for a long time." Annabeth guessed.

"What about friendships you must keep?" Grover reminded everyone.

"I'm not trusting anyone, until I meet them." Percy said, darkly.

"Agreed." Clarisse said, nodding.

"Well, everyone. Our ride is here." Percy notified. He pointed to an ancient looking yellow taxi.

Grover sighed. "Fine, if we have to."

With that, they all filed out of Percy's cabin, and into the taxi, which sped off into the blazing sunny day.

Rose and the Doctor were walking into the TARDIS. The Doctor took one last look at stern, Elizabeth the 1st, before he followed Rose. As soon as the doors shut, they burst out into laughter.

"I am not amused." Rose imitated, between breaths.

"She banished us!" The Doctor laughed. "I've been banished from England!"

"Isn't that bad?" Rose asked.

"Nah, its fine. I kinda always wanted to get banned from somewhere. Now I have!"

"You're an idiot." Rose said, shaking her head.

"But I'm fun to be around. Where should we go next?" The doctor questioned, quickly changing subjects. "I know!" He yelled, answering the question himself.

"Where?" Rose continued.

"It's a surprise."

After a few pumps, a twist of a handle, and the press of a button, the TARDIS began to move, making the miraculous sound it always makes. After a few seconds, it stopped. "Well, go look outside, meet the neighbors!" The doctor suggested.

The sight outside was like nothing Rose had ever seen. She had been to so many places, so many planets, but this. This was different. It was a castle. Not any castle. It was Hogwarts. Roses jaw dropped. "I thought you said Hogwarts didn't exist?"

"Well, it does." He admitted. "If I tell everyone Harry Potter is real, they always go ballistic. So I try to keep it a little secret."

"Would it be weird if I told them how it all ended?" Rose whispered.

"Um, yes. Let's not say that we are from the future." The doctor responded. "Now, we are here for a reason." He held up the psychic paper he always carried around with him. On it, there was a note: Get to Hogwarts. "And I think that we should go and find out why."

They walked down the long corridor, until they found the Great Hall. They opened the huge doors, to see that all the students and teachers were eating dinner. It was then, that they realized that they probably needed to be a student or teacher to not get noticed as much as they did at that moment. The whole room was quiet. Necks turned to stare, and everyone looked either confused or scared.

The Doctor cleared his throat. "Um, hello! I'm The Doctor, and this is Rose, my companion." Rose gave a little wave.

Someone in the crowd yelled, "Doctor who?"

"Just The Doctor, if you will." He replied.

"How did he get in? He's not even a teacher!" Someone else exclaimed.

"Well, um, you see, well, can I speak to the person in charge?" The Doctor stuttered.

Dumbledore stood up. "I assume that you want to make this private?"

"Yes please." The Doctor replied.

"Everyone, enjoy the rest of your meals, I will be having a private conversation in my office." Dumbledore announced.

The Doctor and Rose followed Dumbledore, out of the Great Hall, and up the stairs.

Everyone filed into the room, Dumbledore leading, with Rose and the Doctor walking slowly, observing all the moving pictures, and objects in the room.

"It all looks so real." Rose whispered, thinking only the Doctor could hear.

"Yes, it does, doesn't it?" Dumbledore answered. Rose's eyes grew wide. "But then again, why wouldn't it?" Dumbledore smiled. "Now, what seems to be the problem?"

"Well, first of all, I have a question." The Doctor said. Dumbledore nodded. "What has happened at Hogwarts lately?"

"Do you know of Harry Potter?" The Doctor nodded. "He has just recently witnessed Voldemort come back. He is in his fifth year."

"Oh, ok, so it's a little, busy." The Doctor replied. "Anyways, something is off, in the world. My, spaceship, of sorts, has landed me here, and my job is to figure out why."

"Hmm. I see. Would that be the blue box we passed coming here?"

"Yes. You see, I face a lot of things." The Doctor began.

"What kind of, things?" Dumbledore questioned.

"Well, aliens of sorts. Daleks, Cybermen, Oods, everything you could possibly think of that is alien. Anyways, I think, there is something wrong, in the world, and I need help. It is something I cannot do alone. Maybe, the best students?" The Doctor continued.

"I see. For the best students, to come and help you. To pull them out of school. But to help the world. Hmmm." Dumbledore mumbled to himself. The Doctor leaned his head in, to hear him better. "How does that spaceship of yours work? It looks so small!"

"Oh, well, you know, it's bigger on the inside!

"Naturally. Let's go to the Gryffindor common room. It will be there, that you will find who you are looking for."

They all approached the door to the Common room, but were stopped by a horrible sound. Someone, trying to sing, was failing miserably. "Bubblenickers." Dumbledore said.

"Wait, I will break this glass. Just watch." A fat lady, with a baby pink dress, and dark make-up, held a crystal goblet. She sang a note, incredibly high, and out of her range, that it came out as a screech. Rose and the Doctor held their hands to their ears.

When she realized that it probably was not going to break, she smashed it into the wall next to her. "Aha! Look at my voice!"

"Bubblenickers." Dumbledore repeated.

"Fine." She said, sighing. The door/frame opened, to reveal a room, hidden to anyone that was not in Gryffindor.

"Fantastic!" The Doctor said. Rose looked down. Not that long ago, her Doctor regenerated. Fantastic. That was his favorite word to use.

They all walked down the short hall, to see many students, talking, laughing, and some, doing homework. Everyone froze when they saw Dumbledore. "Hey, it's the weird guy from dinner!" One whispered. "What does he want with us?" Said another.

"Sorry to interrupt, students," Dumbledore began. "This young man is looking for a couple students to help him with a, task." He continued, putting emphasis on the word 'task'. "Ms. Granger?" Dumbledore called.

Hermione Granger, was one of the few people doing homework. She looked up in surprise. "The Doctor was wondering if he could, borrow you, for a moment?" Dumbledore asked politely. Nervous, she stood up, and slowly walked over to the Doctor.

"What kind of help do you need, sir?"

"Ms. Granger is one of the smartest students I know. She will be of aid to you, I assume?" Dumbledore answered.

"Ah, yes. Smartness. Something everyone needs." The Doctor commented.

"Will you go fetch Mr. Ronald Weasley and Harry Potter for me?" Dumbledore asked Fred Weasley. He nodded, and hustled over to the boy's dorms. A minute later, both Ron and Harry approached the Doctor.

"Oh my gosh! I'm actually going to meet Harry Potter!" Rose exclaimed in a low whisper.

"These three are the smartest, most brave students I know at the moment." Dumbledore said, proudly.

"Perfect. Well, let's go!"

Dumbledore followed the Doctor and Rose out of the commons, and the trio suspiciously followed. The Doctor and Rose opened the doors to the blue box, and the three students gaped at the sight. It was bigger on the inside.

They all froze. The Doctor ran to the door. "Well? Are you coming?"

"It's bloody bigger on the inside!" Ron remarked.

"Yes, yes, I know. TARDIS. That's her name. Stands for Time And Relevant Dimensions In Space. Now come on! We're going on an adventure!"

"I'm going." Harry decided, and walked into the TARDIS .

"Same." Ron said, following Harry.

Hermione sighed, "We're definitely going to die this time." She then walked into the TARDIS, and shut the door after her.

Dumbledore smiled, as the blue machine began to fade. "I have a feeling we will see each other again, Doctor." He chuckled, as he strolled back to his office.

Hope you enjoy, please review!
