Ok, so this is my new story. It's set after series three, but before series four. Technically its AU now I suppose…anyway, I hope you enjoy it

Moon, you have a shade of blue tonight –
Is it something that you saw or heard?
Only yesterday, your tone was proud and bright,
Yellow silver, full, and so assured.

Moon, we depend on you to shine
When the sun retires down below.
Add to that your grandest role divine:
Tidal Lord, to keep the seas in tow!

Moon, I hope you take to heart our plea –
Needless is the reason for your blue.
Beaming, you should give the night its glee:
We're despairing – so we look to you.

oxo…oxo

Arthur loved the moon.

He loved the way it lit the castle, the way its beams of light shone of the white walls of stone. In some ways, the thought, it was brighter than the sun. Lighter than the sun.

He preferred it to the sun.

There was just something, dare he say it, magical about the moon, and the way the stars clustered around it. The moon had its many friends surrounding it. The moon was never alone.

The sun was.

The sun didn't have the stars, didn't have its friends to keep it company up there in the sky. It only had the fleeting clouds, always moving and often absent. The sun was lonely; the moon was not.

The sun and the moon; perfect opposites. One came out at night, hidden out of sight from the sleeping people, and yet never alone. The sun shone in the day, always on its own, only able to watch the world go by from high up in the heavens.

He sighed as he stood atop the towers, gazing up at the moon with the chilly night air brushing against him. He had never felt more like the sun. Always praised, looked up to…and yet completely alone.

The night was beautiful, but as he looked down upon the sleeping city of Camelot, his smooth features marred into a frown. A figure, wrapped in a dark cloak, made their way towards the castle, keeping low as to avoid the guards, before slipping through the doors. His frown increased and he made his way down the stairs, towards his room.

There was no one there when he arrived, save Merlin. At first the prince wondered why his manservant was there; he didn't seem to be doing anything. Then he remembered telling Merlin he was to stay until his chambers were tidy. It wasn't that late really, he told himself as the guilt plagued him. It only looked that late outside because of the time of year…right?

He shook it off, opening the door a tad bit more to see what the man was actually doing. He didn't know why he was being so cautious, but he was soon thankful for it as he pulled back swiftly, his heart in his throat and any thoughts of the hooded figure chased from his mind.

He had seen his things, brushes and mops among them, moving on their own. It had to be Merlin. There was no other explanation.

But it didn't seem possible. After all, Merlin was just his manservant, unable of using a sword properly and useless in a fight. There was no way he could have magic…right?

Unsure of himself, the prince looked through the doors again, taking in the flash of gold in Merlin's eyes as his boots flew across the room and into the cupboard. He retreated again, heart and mind racing, certain of what he had seen and yet unable to believe it.

Merlin had magic.

Taking in a deep breath, he decided to go back up to the tower. The moon would help him think. The moon would let him see the answers to all of the questions racing around in his head.

He loved the moon. Loved the way it lit the castle, the way its beams of light shone of the white walls of stone.

But thoughts of the figure came back in a hurry when he reached the turrets, seeing said hooded person standing where he himself had been only a few minutes ago. His eyes narrowed again, his head clearing.

"Who are you?" he demanded, watching as the figure turned to look at him, face swamped in shadow. They didn't answer for the longest moment, and Arthur was about to ask again when they took a step forwards.

"I am who I am," The figure said, the voice beneath the hood deep, rich and masculine. It radiated a power that made the hairs on the back of Arthur's neck stand on end.

"What the hell is that supposed to mean?" the prince replied in a tone that told he meant business.

"It means whatever you want it to mean…or it means nothing at all,"

This only continued to frustrate the prince, and the sharp 'shink' of a sword being pulled from its hilt resounded in the crystal air.

"You will tell me who you are," he threatened, holding his sword up to point at the man's chest. The figure did not move, only continuing to stare at the prince. Or he assumed he was; their face was still covered.

The figure said nothing, instead turning to look out at the forest below the castle. Then he turned back and spoke, but it was not his name that came from his mouth.

"You know of the one called Merlin. You have discovered his lies."

Arthur flinched back slightly in shock.

"How do you know that?" he asked, vulnerable curiosity creeping into his voice. The man chuckled slightly. Darkly.

"I know it, as all who practice magic know Emrys."

Arthur's eyes narrowed in suspicion.

"Then you are a sorcerer?"

It was asked as a question, but the answer was obvious. The man cocked his head in amusement.

"Indeed little prince. I am one of those you would call your dreaded enemies. Yet you have one of your own down in your rooms do you not? One who has lied to you for years?"

"Merlin would not betray me," Arthur snarled, surprising himself as much as the man. The figure took a startled step back at the pure rage in the prince's eyes, before taking a stance that seemed to suggest he was smirking.

"But he already has. You thought he was pure, and yet he uses the very thing you have been taught to despise. Isn't that a betrayal in and of itself?"

Arthur froze, taking in the man's words. What he said was true, Merlin had betrayed his trust…but he couldn't believe Merlin was evil. Merlin and evil just didn't work together. But if Merlin wasn't evil, yet Merlin had magic, then that would mean that magic wasn't evil. That his father was wrong.

That was a big step to take.

But the more he thought about it, the more he realised the truth of it. Perhaps magic wasn't the true evil. Perhaps it was the person who used the magic that decided whether it was good or bad. Like a sword, magic was just a weapon to be wielded in whatever way those who used it saw fit.

He shook his head. "I don't like the fact that Merlin lied to me, but I understand why he did. I know he would never use magic for evil. He doesn't have the capacity for anything but good."

The man growled slightly, enraged.

"You trust the boy that much?"

Arthur felt himself beginning to grin, but it wasn't a nice grin. It was grin that revelled in the man's anger; his plan to enrage the prince into action so obviously failing.

"I trust him with my life."

The man drew back, the aura around him furious, before striding forwards; deflecting the prince's blade as it came towards him.

"Then I will have to do this myself!" he cried out, pulling the hood down to show glowing red eyes and snarling lips. The man's hair was jet black and his face was round and crisscrossed with scars. But as he looked into the man's eyes, he could see the changes happening.

The man's hair was becoming lighter, their jawbone more prominent and defined. His face was smoothing, and becoming thinner, his eyes fading to a baby blue. By the time the transformation had finished, Arthur found himself staring into his own eyes.

The man grinned evilly before whispering a couple of words in the old language, his eyes momentarily turning red. It was then that Arthur realised he could no longer move. Furious, he turned to the man who was gazing at him with his own blue eyes, steeped in hate.

"Don't worry Pendragon. I'll let you have your little life back; just as soon as I have destroyed it."

"What the hell are you doing!" Arthur tried to yell, but it came out more of a choked whisper. The man laughed joyfully at the prince's pain.

"I wanted to get you to do it yourself, but your bond seems to be stronger than I thought. No matter. I'll just dash your pet sorcerer's hopes and dreams myself," the man who was Arthur but not replied, a wicked smirk on his face. Arthur himself growled, attempting to free himself as he watched the figure turn away; walking down the stairs that lead to the prince's chambers.

Dear readers,

Ok, I was planning on continuing this…but my friend said that it's fine the way it is and that I should keep it this way unless people ask for more. He's not a big fan fiction reader though, so I decided that, to prove that it really needs more, I should post it like this and see how many ask for more. Please prove me right! Review and tell me what you think. I think it needs more, how about you?
