AN: Hello. I just wanted to say that if anyone has any suggestions for this FanFic, I'd be happy to consider them. This is really just a bit of fun, so if you want me to send the Doctor, Hermione and Colin somewhere specific, or want something to happen, let me know. Suggestions are good. =)
Also, please bear with me for this chapter. Not a great deal happens, but that's mainly because it's background for the next chapter, which will be much more exciting.

5 – Gringotts

Hermione, Colin and the Doctor walked down Diagon Alley. The Doctor looked around, staring at everything with an open mouth like a tourist.

'Stop that,' said Hermione. 'You can look, but be subtle. No one can know you're a muggle.'

'Right,' said the Doctor, continuing to stare around without the least bit of subtlety.

'Quick,' Hermione said to Colin. 'Let's get him off the main street.'

Colin led them into the bookshop, Flourish and Blotts. Inside, books covered every wall and quite a lot of the floorspace in between. They followed Colin around tables and underneath a twisting staircase, stopping in front of a bookshelf. Colin ran a finger along the shelf, before selecting a book and pulling it down. He flicked through it.

'Here,' he said. 'We're in this one, but we're not named. "Taking the advice of three travelling wizards, a treaty was drawn up and signed."'

Hermione pulled down another book. 'This one too,' she said.

Colin put the first one back and grabbed another. 'There's a picture in this one,' he said.

'There's a what?' said Hermione, reaching out and grabbing the book off him. Sure enough, there was a painting of the three of them slipping through the streets of Hogsmeade on their way to the Three Broomsticks. It was dark, and the artist hadn't done it perfectly, but it was still clearly them. The Doctor looked over her shoulder.

'Why is the picture moving?' he asked.

'Wizard pictures do that,' said Colin.

'How?'

'I dunno. They just do.'

'Listen to what the writer said,' said Hermione. '"After battling their way through the goblin front lines, the young wizards Hermione and Colin, and the older unnamed doctor, made their way to the Hogshead Inn, where they inspired the wizards there to fight. After beating the goblins into retreat with a surprise attack, the wizards forced them to sign a treaty."'

Colin snorted with laughter. 'I don't think they could have been more inaccurate if they'd tried. They even got the pub wrong.'

'But what about the picture?' said Hermione. 'What if someone sees it?'

Colin looked over her shoulder at the picture. 'They might not realise it's us.'

'Yes they will.'

'Look, I admit that it's definitely us, but that's mainly because we know we were there. Anyway, anyone who trusts this historian is clearly an idiot.'

'I guess…'

'There's not a whole lot we can do about it anyway. Come on, I need to get some money out of Gringotts.'

A few minutes later, the three of them were standing in front of a large white marble building.

'Welcome to Gringotts Wizarding Bank,' Colin said to the Doctor.

'This is where you keep all your money?' asked the Doctor.

'Yeah,' said Colin.

'There's other stuff in there too,' said Hermione. 'The bank is run by goblins, which makes it one of the safest places to keep valuables. Goblins protect their money and valuables at any cost.'

'What sort of other stuff?' said the Doctor.

Hermione shrugged. 'It's mainly money in the upper vaults, but down lower, who knows? There's much more protection down there. Some people say there's a dragon, but I don't believe that.'

The Doctor's eyes lit up. 'A dragon? Can we see it?'

'It's just a rumour,' said Hermione. 'Colin and I don't own anything valuable enough to warrant a deposit box that far down. There probably isn't a dragon anyway.'

'All the same,' said the Doctor, 'it'd be a shame not to find out.'

'No way. Do not try and break into Gringotts. There's only ever been one successful break in, in 1991, and the thieves didn't get anything anyway, because the box they broke into had been emptied earlier that day.'

'All right. I won't try and break in.'

Hermione looked at him suspiciously. He didn't sound very sincere. 'You won't try and break into any of the safety deposit boxes?'

'Cross my hearts.'

'Don't you mean "heart"?' said Colin.

'Nope. You humans and you're one heart. It's pitiful. How do you cope?'

'How many do you have?'

'Two. Almost killed me once, when a human doctor got their hands on me. They thought my heart was going to explode or something. They sedated me and almost stuffed up the regeneration process. I woke up hours later with no memory.'

'Regeneration?' said Hermione.

'Time Lord thing. Come on. Let's go see the goblin bank.'

'Fine. But no break ins.'

They walked up the steps and through the burnished bronze doors flanked by goblins. Inside were another set of silver doors, also flanked by goblins, with a warning engraved across them.

'I like that,' said the Doctor, reading the inscription. 'Poetic and deadly.'

Enter, stranger, but take heed

Of what awaits the sin of greed

For those who take, but do not earn,

Must pay most dearly in their turn.

So if you seek beneath our floors

A treasure that was never yours,

Thief, you have been warned, beware

Of finding more than treasure there.

'Finding more than treasure there,' said the Doctor. 'Interesting.'

Hermione noticed that the two goblins were giving them strange looks. 'Inside,' she said, giving him a push. They stepped through the silver doors and into the main hall. About a hundred counters ran down either side of the room. A goblin sat at each. Wizards and goblins moved about the hall, coming and going and everything in between. Colin led them to an empty counter.

'I'd like to open my vault,' he said to the goblin.

'Very well,' said the goblin, glancing at them. Then he did a double take. Then he started outright staring at the Doctor.

'Hello,' said the Doctor. 'I'm the Doctor.'

The goblin's stare got even more intense. Then he pointed a crooked finger at Colin. 'You are Colin?'

'Yeah,' said Colin.

The finger moved to Hermione. 'Hermione?'

'Yes. How did you know?'

'You were at the goblin rebellion of 1612.'

Hermione started, paled, and then said, 'I…what? That wasn't us. How could that have been us? That was four hundred years ago. We couldn't possibly have been there.'

'Hermione, you need to work on your lying,' Colin whispered.

The goblin was shaking his head. 'No, it's definitely you. There are only a few paintings in existence of the three mysterious travellers who appeared from nowhere, resolved the goblin rebellion in an hour, then disappeared just as mysteriously, but it's you. I recognise the strange clothes of the unnamed doctor, and the extreme hair of Hermione, and Colin's camera. It's definitely you. You three are well known in goblin lore. Despite the fact that the rebellions started again years later, the treaty instigated in the 1612 rebellion saved many goblin lives.'

'And wizard lives,' said Hermione.

'Yes, well, I suppose that couldn't be helped. Still, you did your best.'

'For the record, it's not 'unnamed',' said the Doctor. 'My name is the Doctor.'

'Doctor who?'

'Just the Doctor. That's it.'

'Really?'

'Yes.'

'Can we get money out of my vault now?' said Colin.

'Of course,' said the goblin. 'It would be my pleasure to escort ancient heroes through our bank. May I have your key?'

Colin handed over a small gold key. The goblin took it, examined it, and handed it back.

'Follow me, please,' he said, climbing down from the counter and leading them through one of a multitude of side doors.
