"Where are we going?" Amy asked as the Doctor leapt and danced around the TARDIS console. She wondered if he'd ever considered taking up gymnastics.

"It's a surprise!" the Doctor paused only to twist a dial and flash Amy that cheeky, excited grin she knew so well. The TARDIS came to an abrupt halt and silenced, waiting eagerly for its next command. "Here we are!" the Doctor straightened his bow-tie and opened the door. "After you." Amy stepped out of the safety of the TARDIS and took in her surroundings. They were outside a big city with marble walls that were coated white in sunlight. Further up, Amy could see the turrets of an equally white citadel.

Even from this distance, Amy could tell the city was medieval. Over the bustle of people coming and going, she could hear the faint sound of music. It was unlike any music she had heard before, and to say it was old-fashioned would have been an understatement. She was sure that it must have been at least six centuries before her time, but the Doctor would find that boring. No, this had to be at least a millennium ago, maybe more.

"So?" the Doctor broke their silence. "Where are we?" Amy thought for a moment.

"We're still in Britain," she said. The Doctor nodded, "But it's about... 500 AD?"

"Ooh," the Doctor smiled, "You're so close! It's 467 AD - Camelot." Amy's confused face erupted into a gigantic grin at the word. She had dreamed of coming to such a magical place since she was a little kid. But she had to be sure.

"You mean... King Arthur and the Lady Guinevere and Merlin and the Round Table?" the Doctor nodded and Amy hugged him. She suddenly became a child again, taking his wrist and dragging him towards the gates, like a toddler dragging her father towards the petting zoo.

The two travellers got some odd looks as they walked through the gates of Camelot. One man, who seemed much better attired than those around him, stopped them in their tracks.

"I'm sorry," he said very unapologetically, "But your clothes seem somewhat... different to those around you." The Doctor looked him up and down.

"So do you, my friend, but you don't see me complaining."

"I'm sorry," he said again, glaring at the Doctor, "Do you know me?"

"Not personally, no."

"So, therefore, I am not your friend."

"Oh," the Doctor looked at him sympathetically, assessing the situation. "That's a rather depressing way to look at life. I like to think of everyone as my friend. I don't see you being an exception, unless you have any particular reason to hate me."

"Well, if you're distressing my people, I'm afraid I'll have to take action."

"I don't see the problem. I you have any decent sense, you'll know that bow-ties are cool." At this, the man started to get angry.

"Do you know who you're talking to?" he growled. Their conversation was starting to attract a crowd.

"I'm hoping... a human?" he checked. "Or have I come to the wrong planet again?" at this, Amy laughed. She noticed another man near the front of the crowd stifle a laugh as well. The Doctor noticed two heavily-armed guards approaching him.

"I suppose you think you're funny?" the man narrowed his eyes.

"Well, I try to be modest," he said smugly, "Unlike someone I could mention." Now his blood was up. The guards grabbed him.

"On your knees!" he drew his sword and the Doctor obeyed him. Amy decided it best to do the same. "You should be showing more respect towards your king!" the Doctor groaned.

"Of course, you're King Arthur!" he sighed.

"Please excuse him," Amy told Arthur, "He goes a bit over the top sometimes."

"What are your names?" Arthur demanded.

"I'm Amy," she replied, "Big-Mouth here is the Doctor."

"I would have expected a physician to be more mature."

"Please," the Doctor said quickly, "This is Lady Amelia, of the Pond District. I am her personal doctor."

"The Pond District?" Arthur repeated suspiciously. "I haven't heard of it."

"Oh," Amy chipped in, "It's very far away, in the land of..." she thought a moment, "Milton Keynes."

"I don't know it," Arthur admitted, "But I can see that you have travelled far. I will have rooms prepared for you at once." He turned around and beckoned to the man Amy had noticed earlier. "Merlin, could you excort them upstairs?" the man nodded.

"Sorry," Amy said, "But, Arthur called you 'Merlin'." The man turned.

"Yes," he replied, "That's my name."

"Are there any other Merlins in Camelot?"

"Not that I know of."

"Well then, it must be you," Amy concluded, "But, I must say, I thought you'd be... older." Merlin stopped dead.

"How do you know of me?"

"How do you think?" the Doctor laughed. "Merlin, the greatest warlock in history?" Merlin turned pale.

"Please, keep that to yourselves," he murmured, "No-one else can know."

"Why not?"

"Magic has been banned here for over twenty years." Amy and the Doctor exchanged concerned looks. "Ever since the Lady Ygraine died at the hands of magic, Uther had been convinced that all magic was evil. The likes of me has to stay in hiding until Arthur lifts the ban."
