Sorry for the long update! I had really bad writers block with this, I just had no idea where I was going. But now I think I'm fairly back on track, and hopefully I'll be able to update a bit sooner next time!

Disclaimer: I don't own Doctor Who. Or Hitchhiker's Guide, which I have once again stolen from.

Rose stared at the Doctor for a moment.

"Who?" she asked, "Who's alive?"

"All of them… everyone…" he whispered, "they never died." Rose thought about this.

"The Time Lords?" she asked quietly. He looked over at her.

"And the Daleks," he added.

"How?" she asked, "I thought you could sense them if they were alive."

"I can, but they're not there to be sensed," he answered, making Rose even more confused. He turned to her to explain.

"In this universe, the Time Lords knew that they were losing, so they locked the Daleks in a Time Envelope. In a Time Envelope, time goes almost infinitely slow, so that at the end of the universe when every other living thing is dead the pressure and energy created by the end of the universe would release the Daleks from the Envelope, and because it's the end of the universe it wouldn't matter if they escaped. But things went a bit wrong and the only way to imprison the Daleks was so imprison themselves as well, but they managed to do this in a different Time Envelope. So they're both gone, undetectable to the outside universe," he looked down at the orb he held in his hands, "This message was sent out to any Time Lords that, for some reason, weren't in the Time Envelope. It located the Time Lord technology and locked on." He paused, staring at the orb, deep in thought.

"So can't you open the Time Lords' envelope and release them?" Rose asked.

"No," he answered, shaking his head, "not without unlocking the Daleks' as well. The two envelopes are connected. Open one and you open the other. This orb was set to activate if either of the envelopes were being opened…" he trailed off for a moment, as his eyes widened in realisation. "That's what happened, that's why it started glowing. Someone's trying to open the Time Envelopes," he frowned, shaking his head, "but it has to be someone on the outside, otherwise the orb wouldn't know to activate. But to open it from the outside would require enormous amounts of energy, an almost infinite supply of energy…" he trailed off again, as his eyes grew even wider. "Like Jack," he said quietly.

Martha sat outside the TARDIS, watching it in silence. Rose had been in there for ages and she was beginning to debate whether to go in there herself. She sighed and shifted in her position slightly, leaning back more. Just as she did so, Mickey walked into the room and sat next to her.

"Hi," he said, "we haven't really been introduced, so I thought I'd introduce myself. I'm Mickey Smith," he held his hand out and she shook it.

"Martha Jones," she said. She glanced over to the TARDIS. "So how do you know the Doctor?" she asked.

"I'm an old friend of Rose. Well, I was her boyfriend until he came along," he said, somewhat bitterly.

"He stole her from you?" Martha asked.

"Yeah, took her away and they didn't come back for a year. They thought I'd murdered her! When they got back, she'd only been gone a few days." Martha couldn't help but snigger.

"Sounds like the Doctor," she said.

"Yeah, well he was a different man back then. But then he did something. Changed his face. Something alien." Martha looked at him in confusion.

"What do you mean?" she asked.

"Doesn't matter, long story," he said. Before Martha could pursue the matter, Jake and Jackie came running into the room, Jackie clutching Aurora.

"Mickey, they've found us!" Jake said urgently, "Torchwood are coming." Martha quickly stood up.

"We'd better tell the Doctor then," she said, and they were about to run to the TARDIS until the Doctor suddenly flung the door open and ran out.

"I've done it!" he said excitedly, "The TARDIS is working!"

"Great, 'cause we've gotta go!" Martha said.

"Why?"

"Torchwood are here," Jake answered.

"Oh, right, well, that's useful I was just about to suggest we leave. Let's go!" he ran back into the TARDIS and they quickly followed him in.

As they entered the TARDIS, the Doctor ran to the console and started the engines up. On the console sat the orb, glowing as the central column moved up and down.

"Did you get the message in the end?" Martha asked, eying the orb.

"Oh yes!" the Doctor shouted triumphantly as he ran around the console, "Turns out the Daleks and the Time Lords are still alive, both locked in a Time Envelope. The orb was made to activate if someone tried to open the envelopes, so I linked it to the TARDIS, which then was able to connect to the vortex which means we now have power!" he hit a button and the TARDIS shook violently, throwing them to the side. "The orb is leading us to whoever's trying to open the Envelopes, and with any luck, Jack's there too." The room juddered as the TARDIS landed. The Doctor leapt from the console towards the doors and ran out. Martha, Jake and Mickey followed him out. Jackie stood for a moment watching the door, holding Aurora close to her. Rose walked up to her.

"Mum, maybe you should stay here," she suggested, "it's safer." Jackie nodded, and Rose too headed out the doors.

Outside, the Doctor was leading the group through the winding maze of corridors, and Rose had to run to catch up with them. As she reached him, she saw that he had his sonic screwdriver out and was using it to show him where to go.

They walked through the empty corridors for what seemed like ages, until finally they heard something in the distance. Voices. The Doctor indicated for them to be quiet, as they slowly made their way towards the noise.

They turned a corner and found a balcony. They slowly walked towards it, making sure not to be spotted by whoever was in the room. As they got closer, they could hear what the voices were saying.

"…how about you tell me a bit about yourself." They all breathed a sigh of relief as they heard Jack's voice. They reached the end of the balcony and looked over the edge, down into the room beneath them. They saw Jack strapped onto some sort of machine, with a man dressed in black standing opposite him, next to what looked like a control panel.

"Pity you're so unwilling to cooperate. Well, I'll have to find out from your friends when they get here, which I'm sure won't be long. But they probably think you'll be ok, what with being immortal and all," the man said, turning to the control panel.

"It can't be," the Doctor whispered as he looked over the machine.

"What is it?" Rose asked quietly. The Doctor was about to answer, when Jack interrupted.

"How do you know so much about me?" he demanded.

"I told you, I've been watching you. And scanning you. I never would have thought a human could have such a power," the man turned to the control panel and started fiddling with the controls. The Doctor's eyes widened as he watched.

"We've got to get down there," he whispered urgently.

"You really are going to be part of something big, Jack, Something even your friends wouldn't be able to save you from." The Doctor leaned over the balcony looking for a quick way down, knowing that there wouldn't be enough time to go running through the corridors. "Too bad you'll be dead before you can find out what it is." The group gasped as the man pulled down a lever, and suddenly the machine came to life as bright white electricity covered Jack. He screamed in pain as the electricity lit up the room.

"No!" the Doctor gasped, reaching for his sonic screwdriver. He pointed it at the machine as the man below began to laugh. "I'm not close enough!" he said angrily, "I need to get down there…" he took one last look up, then saw how to get down. Hanging from the ceiling were a number of chains, out of reach from the balcony. So he climbed onto the top of the fence at the edge of the floor.

"No, don't…!" Rose shouted in protest, but it was too late. He'd already jumped off and grabbed hold of one of the chains. He swung for a moment in the air, before letting go of the chain and falling downwards. As he fell, he held out the sonic screwdriver to the machine and turned it on. Sparks began to fly from the machine as it crackled and eventually turned off. The man watched in anger as the Doctor landed on the ground, his trench coat flying out behind him. He put the sonic screwdriver back in his jacket, aware that behind him Jack was unconscious.

"So, Doctor, we meet at last," the man said, "I was wondering when you'd get here. And, of course, your friends," he looked upwards to the balcony.

"You seem to know a lot about us," the Doctor said, causing the man to look back down at him, "and like Jack said, I think it's about time we knew about you, Time Lord."

"You say that as if it's an insult."

"Maybe it is. Why weren't you in the War?"

"I could ask you the same question, Time Lord." The Doctor gave a small smile before answering.

"I'm not from this universe," he said, "I wasn't in your War." The man frowned at him.

"But that's impossible," he said quietly.

"That's what I thought. But I've proved myself wrong enough times." The man nodded.

"So why do you come here?" he asked.

"To get my friend," he answered, "you may have known, this universe was colliding with another. Some Daleks from my universe hid in the void, but they pushed their way back through, and with them came the Cybermen from the Earth in this universe. I had to seal the breach, but she got trapped here in the process. I came to get her back."

"I… see," the man said slowly, "these Daleks, they were from your universe?"

"Yes," the Doctor replied, "why?"

"I thought they must have been from this universe," he said thoughtfully, "I thought they were trying to get back through, so I gave them a nudge in the other direction." The Doctor's eyes widened as he realised what this meant.

"You… you pushed them into my universe?!" he shouted accusingly.

"So it would appear," the man answered. The Doctor was bristling with anger.

"All the people that died… everything that happened… it was all you," he growled. Behind him, he heard Jack groan as he began to regain consciousness. "Tell me, what are you planning to do with Jack?" he demanded.

"Haven't you figured it out?" he answered, "There are so many different types of power, but life itself, when harnessed, can be the most powerful of all. It is with this power that I shall release the Time Lords." The Doctor couldn't help but laugh.

"But don't you get it?" he said, "You can't release the Time Lords without releasing the Daleks too!"

"With enough power you can."

"But you can't!"

"You're not even from this universe, what would you know?"

"Things can't be that different between universes."

"Oh I think they can. But… perhaps you need a little convincing. If you hadn't broken my machine I could show you." The Doctor sighed and shook his head. There was no way he was risking releasing the Daleks in this universe, he had enough Daleks to deal with in his own universe.

"Before I rescue my friend and stop all this, do tell me, who are you?" The man gave him a small smile.

"I am the Master," he said. The Doctor's eyes widened, as there was a small gasp from somewhere above them. "Judging by your reactions, I'm guessing you know the me from your universe."

"And judging by your reaction I'd guess you don't know the me from this universe." The Master shook his head. "Right, well that settles it, if you don't know me I officially don't exist in this universe." He took one last look at the machine. It still hadn't quite sunk in. The Time Lords in this universe… were alive. "And maybe that's just as well," he muttered. Before the Master could say anything, he spun around and pointed the sonic screwdriver at the cuffs harnessing Jack to the wall, and broke them open. Jack fell to the ground and landed on his feet. "Back to the TARDIS!" he shouted, running out of the room with Jack following, hoping the others had heard him.

The Master glared at them in anger, and was about to run after them when he felt a hand on his shoulder. He looked back to see a man step out from the shadows behind him. He was also dressed in black, and had a small smile.

"Leave them," he said calmly. "He won't escape for long. It is only a matter of time until the Time Lords shall be released." The Master watched the man for a second, before it all made sense to him. He looked forward with a smile, as the echoes of TARDIS engines floated down the corridor.
