There are all sorts of methods of time travel.

Some methods are fun and comfortable, like the TARDIS.

Some are a bit more amateur.

Usually, those will be in the form of bracelets or pendants.

The Doctor, however, prefers his big, (sometimes) dependable ship.

He'd rather not mess with other, less impressive forms of time travel.

Some people, however, have got no other choice.

Chapter 1

There are many 'lasts' in the world of time travel.

There is the Doctor, the last of the timelords. And his TARDIS. That's the last one, too.

But there are other lasts, as well. Like the last Time Turner.

Rose found it in Scotland.

It was a golden glimmer in the grass, on their way back from their encounter with Queen Victoria.

She stooped down to pick it up and showed it to the Doctor.

"Where'd you get that?" he asked, still in the Scottish accent he had acquired during the trip.

"Found it here…" she said, pointing at the spot on the grass where she'd seen it. "Maybe it's the Queen's."

"Let me have a look."

The pendant was made of two golden circles, and a small hourglass in the middle, held by a golden chain. There should have been two knobs on the outside of it, but one had been broken off, probably by accident.

"I don't think it's the Queen's…" he said finally, after a moment of silently examining the odd item.

"Who's do you reckon it is, then?"

"I don't know, but it feels… odd. Look at this."

He pointed at the golden circles, and Rose saw something she hadn't noticed before. They were decorated with small, beautifully written words, one sentence on each side of each circle. Rose read them in the wrong order at first, then turned them over in her head until she had the right order.

I mark the hours every one

Nor have I yet outrun the sun

My use and value unto you

Are gauged by what you have to do

She said it out loud, the Doctor joining her at the last sentence.

"What does it mean?" she asked.

The Doctor shook his head. He didn't know what it was. He had never seen anything like it. But he felt something coming from the pendant. Something about it just felt… magical. He couldn't quite find another word to explain it. And it felt familiar. It felt, strangely, like home…

Of course, it couldn't be from Gallifrey. No way. He'd have known if it was. But he felt like it was something that would have been welcome on Gallifrey. He couldn't quite put his finger on why. It just felt that way.

They took it back to the TARDIS, where they looked at it for a while, turning the one knob, trying to make it do something. Nothing worked.

"What're we gonna do with it?" Rose asked, holding the necklace carefully. It was beautiful. Not in a regular way. It felt, to her, like something that was part of the Doctor. That was what was beautiful about it. She couldn't explain it, but it was there… Some kind of power that it shared with him. Some kind of feeling, like a familiar smell, but better than that.

"I think it's safe to wear, if you want… You can wear it," he said. "Until we figure out what it is. And it'd look funny if I was the one who wore it… So you can wear it."

She let him fasten it for her. His fingers lingered a bit too long at her neck after he was done.

For a short moment neither of them said anything. Rose wasn't sure if she was thinking a lot or not thinking at all.

"So are you sure it's not dangerous?" she finally asked, just to break the strange momentary tension.

"What?"

She motioned to the necklace. He looked at it blankly, as if forgetting what they'd just talked about, and his eyes lingered on her chest for a moment too long.

"Ahh, right! The necklace! I lost my train of thought there for a second… I don't really know… Just keep it, for the moment, I guess. Just keep it and see what happens."

At that moment the TARDIS started shaking and rattling uncontrollably, sending both of them to the floor, Rose holding on to the Doctor's arm in a slightly awkward way, the Doctor holding on to the side of the TARDIS as it shook.

After what could have been a minute, but since they were in the TARDIS, it was really impossible to know, the shaking stopped. The Doctor helped Rose to her feet, panting.

"Where are we?" she asked.

The Doctor walked to the TARDIS control screen and looked at it for a long time, unmoving. Seeing that he wasn't about to answer her, she came to look too.

The screen read:
