~CHAPTER ONE~

No one paid any mind to the raven haired teen as he appeared to wander aimlessly through the streets of London. Considering he was moving through the outskirts at the current time, he was being regarded as one of the homeless. It didn't really seem to matter that it was the middle of the night. He held the bags of stolen goods close, emerald eyes peering warily out from behind round wire rimmed glasses.

He ducked into an abandoned alleyway, glancing behind himself momentarily. Shouts broke out further down the main road as his theft was discovered too late. He rounded the bend and slipped out the other end unnoticed. He then calmly made his way through the streets until he reached an old abandoned warehouse.

The teen lightly tapped the padlock on the gate with a finger. A soft click resounded and he hastily undid the chain, crossed the threshold before closing the gate and locking it. He grinned as he turned and walked to a door reading: AUTHORISED PERSONEL ONLY.

He rapped the door frame lightly with his knuckles before he murmured "Phoenix."

A female voiced breathed back. "Harry." There was the sound of locks being undone and the door glided open smoothly. A red haired woman about the age of seventeen stood behind it.

"Ginny." Harry looked around before stepping through. He shut the door behind himself bathing the room in darkness and slid the dead bolt in place before locking the rest of it. "Are Ron and Hermione back yet?"

"Not yet, they should be very soon. Neville and Luna are already downstairs."

"Good." Harry nodded. "I got them."

"Really?"

Harry grinned, he could hear the excitement in her voice. "Yep, and I managed to snag a decent dinner too. I'll head downstairs, keep on look out for Ron and Hermione."

"Ok."

With practiced ease, Harry made his way through the dark and found the cold, metal railing of the stairs. He descended quietly, shoes making little noise against the metal. At the end of the stairs there was a long corridor, a dim glow at the far end. Harry headed for the light and pressed his hand against the adjacent wall. There was a hiss, similar to the sound made when air pressure is released. The "wall" slid upwards, revealing another room.

Harry entered the room only pausing to press his hand to a panel next to the doorway causing it to slide closed again. He crossed the sparsely decorated room bouncing slightly with excitement and sank into a battered armchair.

"You look like you enjoyed yourself." Neville, a round faced boy around the same age as Harry, said without looking up from his computer. The tapping of keys could be heard as his fingers sped across the keyboard.

"Well," Harry said allowing himself a small smile, "I have to admit it's far more interesting being chased by muggles than Death Eaters. Not nearly as stressful."

"Yeah, I suppose so." Neville sighed, typing ceased for a moment. "It's still dangerous though and you're supposed to be the leader round here. If you can't take a chase seriously, Merlin help us."

Harry laughed before looking over at Luna who was sitting on a rusty lawn chair opposite him. "Watcha reading, Luna?"

"Some muggles seem to be very good at guessing things. Yet they still get called mad for it. It's strange though, many of the things that they see are from our world, not this one." Luna flashed the cover of the magazine about cryptozoology at Harry. The blonde dreamer returned to her reading.

"Hmm, it is strange, not a single magical thing about this world. I'd say we should investigate but right now it's more important that we get the Gate up and running." Harry stood up, suddenly grim. "Only problem is, we don't know how much time has passed since we were in our own world."

"What do you mean?" Neville asked, shutting off the computer.

"Hermione said, when we first came here, that could move at a different speed in different dimensions. For instance, a month here could be an hour there and vice versa. Twenty years could have passed there by now and we would look no older than we do now."

"Which is why the sooner we get the Gate finished, the better." Hermione finished striding into the room, Ron and Ginny behind her.

"Oh good, you're back. Did you get the parts?" Harry said sitting back down.

"Sure did." Ron replied cheerfully. "Spose you did your bit to then?"

"Oh yeah, and I got dinner too. Should be enough to last the next few days." Harry reach down and revealed the couple of bags full of items that he'd swiped.

"Brilliant! I'm starving. What did ya find?" Ron exclaimed in delight.

"Well, let's see," Harry said unpacking the contents. "we've got canned soup, some apples, loaf of bread and a jar of honey."

"Good haul, I don't think we've gotten that much bef-"

There was a loud crash from above startling the group.

"What was that?" Ginny whispered.

Another crash resounded above. "They've found us!" Harry hissed, expression darkening. "Time to go!"

"But what about all our equipment? Everything we've done so far?" Hermione gasped.

Harry hesitated and glanced around the room. Loud footfalls and yells could be heard now.

"There's no time! They'll be here any minute!" Neville yelled.

Harry nodded and grabbed Hermione's arm. "I'm sorry."

They ran, ducking into a side passage. They'd all been prepared for the moment they'd be discovered and made sure that they had an escape route planned out. After a few minutes of running the tunnel began to slope upwards until they reached a set of double doors. Not even hesitating, the group burst through into the pale glint of dawn light.

They'd emerged in a dump yard, just outside the edges of London. They didn't stop running. They could still hear their hunters behind them, thundering footsteps getting louder as they closed in on the teens. The group did not falter not even when the black dressed figures came running down from behind the mounds of rubbish.

The sudden click of firearms being loaded did make them stop though. They halted gasping for breath as they were circled by the men. They were surrounded.

"Dammit." Harry growled his friends still behind him.

"Bravo." A man cried out from behind the gunmen. "I must admit you all put up a good fight, but surely you must have known you would have been caught eventually." He stepped forward smiling at the teens. His hair was neatly combed and he was wearing a black suit.

"No reason why we shouldn't try." Harry replied looking at the man with distaste. He glanced around at the circle of guns pointed at them. "We must be pretty important if you went to all this trouble. We even got you back in London. Was the ambush really necessary?"

"You and your friends have a talent for escaping me. I couldn't risk that happening."

"I thought we already explained that we're as human as they come. We're not what you think we are."

At this the man smirked. "The DNA analysis disagrees with you."

"Then it's wrong. Let us go, we're just trying to go home."

"No. I already told you what it is I do." He turned to the nearest gunman. "Load them all into the choppers. If they try to escape, shoot to stun not kill. I want them alive." He then turned and began to walk away.

As the soldiers converged on them Harry yelled out to the man's retreating back "You won't get away with this van Statten!"

He only smiled at the struggling teens.

6 months later...

Six months had passed. Six months of torture and captivity. Six months since Harry had last seen his friends. At first he had resisted, suffered in silence. Then, one of the guards who was assigned to his cell had brought the news that Ginny was dead. When Neville had been killed he'd struggled and screamed for help. No one came. Then came Luna's death. Ron and Hermione had lasted nearly five months. Harry was the only one left, fighting to survive with no reason to. He'd given up on the hope of returning home long ago.

Van Statten was convinced that they were aliens; he'd believe it ever since he'd seen Hermione unlock a door by tapping it the first time they'd met. Three years ago that had been. They were aware of the technology van Statten was hoarding and had attempted to steal some of it. Naturally they'd been caught. A DNA scan had come up non human not long after that and he'd been chasing them ever since. They only escaped by the carelessness of a guard and pure chance. It was all over now though. All Harry could do was reminisce over his whole life in his breaks between the testing that he preferred to call torture much to the scientist's discomfort.

It hadn't been easy adjusting to life in a universe without magic. They searched everywhere to find signs of the wizarding world but it didn't even exist. A world without magic made it impossible to use magic. They'd ended up abandoning their wands as they were basically nothing but sticks now. Then, when they'd begun to study the sciences and understand the mechanics of the world around them they were able to use it again. Except it was different now. Not magic. Manipulation of the particles, wandless and nonverbal. Harry wasn't completely sure of how exactly it worked; Hermione understood it better than all of them did.

They'd decided to build a way back home. They'd studied everything they could about modern sciences, learnt to blend in with the muggles perfectly. Then they'd started to steal technology to try and build their "Gateway" home.

A year after they'd started Hermione had realised that they couldn't go back. She started making excuses, saying that the calibrations were wrong; time zones between dimensions were different and had to be synchronised. Harry had confronted her about it. She'd explained then that their universe was gone. It had been destroyed when they'd fallen through. They didn't tell the others, unwilling to destroy what little hope they had left, almost thankful that they often had to move and leave behind majority of their work, start again from almost scratch. In the end, Harry knew they'd worked it out too. They were never going home because there was no home left.

Now here Harry was, the last of the wizards, chained up and being monitored at all times by machines, tested from time to time by scientist so they could know how exactly he worked, not ever listening to him, only ever asking what he was and where he came from to which he would always reply "Human" and "Earth". He knew his friends had been put through the same agony and they hadn't been strong enough. Six months of this pain and loss.

Then one day, there were shouts from above and around; something was amiss. Explosions and alarms sounded. The air stirred around him, practically begging him to use the particles, to bend them to his will once more. The day Harry escaped.

The day Harry Potter met the Doctor.

AN: Um yeah, I killed everyone except Harry. Oops. Did I forget to mention that I'm a sadistic bitch? Maybe I should have said something.

Too late now. YAY. But on another note, this is the first crossover I have written so please be nice.

Review please!
