Memories swam around his mind.

"You're such an idiot, Merlin!" …."Takes one to know one…"

"Do I know you?"…. "Er, I'm Merlin."…. "So I don't know you."…. "….No…"… "And yet you called me 'friend'."…. "Yeah… that was my mistake."….. "Yes, it was."...… "I could never have a friend who could be such an ass."

"…I've been trained to kill since birth."…. "Oh, and how long have you been training to be a prat?" ….."You can't address me that way!"…. "Oh, then, how long have you been training to be a prat, my Lord?"

"I could take you apart in one blow!"….. "I could take you apart in less than that."

"Merlin, I'm really not interested in your favourite bedtime stories."… "For once in your life… just, LISTEN."

"I'll get him a pillow."… "Merlin! He's the King!"….. "Alright then, fine, TWO pillows…"

"I'm a sorcerer… I have magic."…. "Get away from me!"

"All this time, Merlin. You never once seeked any recognition."….. "That's not why I do it."

"I don't want you to change. I want you to be YOU."

Eyelids fluttering weakly, Merlin stirred. Looking around his surroundings cautiously, the first thing he noticed was that he was in an extremely comfy bed, with royal red blankets and soft velvet sheets, with Pendragon red drapes. At first Merlin just thought that he's drifted off to sleep while changing Arthur's sheets again; but then, he remembered Camlann, and the centuries in hiding. He jolted upright in alarm and cried out in agony when his left side stung painfully.

"Don't get up, you'll only hurt yourself further." A grey-haired woman with spectacles told him kindly, sitting on a chair In front of the bed. McGonagall eyed him with appraised eyes when Merlin's own eyes shot about the room in fear and shock.

"Where am I?" he asked, terrified.

"You're at Hogwarts." Professor McGonagall informed him. "Madame Pomfrey fixed up your ribs, but she said they'll be a little achy."

"'Achy' is an understatement." Merlin grumbled under his breath. "I feel like I've ran to the Western Isles and back again."

McGonagall shot him a curious, confused look, before rising and stating, "I'll go fetch Dumbledore; he's been waiting for you to wake up."

"How long was I unconscious?" Merlin asked, alarmed.

"Four days." McGonagall told him.

"Damn it." Merlin moaned, sinking back into the blankets, his hands on his face. "Arthur is really, really going to kill me."

"I'll remind you, boy, that you are no longer in Camelot." McGonagall told him not unkindly, but firmly.

Merlin's eyes widened. Damn it, that meant she knew. She knew about his magic and who he was and what he had done. Merlin only groaned more, his face in his hands. McGonagall gave him a shaky smile, and it was clear she was slightly afraid of him. She left the room without another word.

The chambers were much like Arthur's, when he had been King in Camelot. They were spacious and roomy, with red and gold drapes and curtains, a large four poster bed and a desk with paperwork on it, with a lit candle. Merlin leaned forwards to touch a drape and frowned when he found the Pendragon emblem embroidered into it.

"The Pendragons are famous amongst all folk." Stated a caring voice, from the door.

Merlin looked up and found Dumbledore gazing down at him, his eyes twinkling. "The House of Pendragon is long gone." Merlin murmured. "All traces of their history vanished when Guinevere's son died."

"And yet, we know the truth." Dumbledore sighed. "And we know that the history has not vanished, just simply was not shared."

"Maybe it wasn't shared for a good reason."

Dumbledore stared at him, amused. "Yes, I'm sure that's the case."

Merlin groaned and turned away, burying his face in the pillow. "This is so embarrassing."

"Maybe for you." Dumbledore said. "But not for an old man like me."

"I'm older than you." Merlin mumbled. "I'm over four centuries old."

"Ah yes, but that depends, you see." Dumbledore said, infuriatingly. "For is that age physical or mental? I think it may be neither. It is simply a number for you."

Merlin groaned again, causing Dumbledore to laugh. The Headmaster took a seat at the side of the bed, his eyes sparkling with curiosity. Merlin clambered out of bed to find he was wearing some simple striped pyjamas from the Hospital Wing. He grabbed his freshly washed clothes from the table and hurried to change behind a screen. Once he was back in his comfortably old trousers, red cotton shirt and signature neckerchief, he relaxed a little. He was surprised to find that the coat of arms of the House of Pendragon had been embroidered in gold onto the corner of his neckerchief, but wore it anyway, proud to be sporting Arthur's emblem. He joined Dumbledore at the table and they both just sat there, staring into space.

"How many people know?" Merlin finally asked, his voice breaking on the last word in half-fear and half-horror.

"Not many." The Headmaster reassured him. "The Order of the Phoenix… Mr Potter, Miss Granger, Mr Weasley, Miss Weasley, Miss Lovegood, Mr Longbottom, Mr Weasley, Mr Weasley, a few members of the Ministry and the Minister himself."

"How many people are going to know?" Merlin changed his question, his expression worried and fearful.

Dumbledore gazed at him. "As far as I know, just them." He said quietly.

Merlin hesitated, before stating, "I don't want to be worshipped or treated like a God. For over five centuries people have used my name like it's there to be bowed down to. I want things to be like they were in Camelot. I want to be able to say, 'Hello, I'm Merlin' and not face things that I don't want, like fame and fortune."

Dumbledore nodded understandingly. "Yes, I'm sure that's true." He stood up, clasping his hands in front of him. "Now, there are several people in my office that have been wanting to see you for quite some time. Will you join us?"

Merlin squeezed his eyes shut. He instinctively reached for Excalibur's hilt. He immediately felt relief when he grasped the familiar sword's hilt in his right hand. He inhaled deeply before nodding. "I guess I can't ignore the modern world now…"

Dumbledore opened the door, smiling at him kindly before striding out of the chambers confidently. Merlin grinned weakly before scuttling after him, locking the door behind him with a muttered spell. Dumbledore looked curious, but didn't ask. Merlin fidgeted nervously while he followed Dumbledore through the maze of corridors towards the Headmaster's office. Dumbledore mumbled the password to the gargoyles and they nodded, stepping aside to allow the two warlocks to pass. The gargoyles stared in shock when Merlin stumbled past them and the warlock felt his cheeks burn with heat and glared at the floor.

"Wait here." The Headmaster told him calmly.

Merlin waited anxiously outside the office and jumped when he heard an outburst of arguing from inside the office. Pacing fretfully, he nearly leapt out of his skin when Dumbledore stuck his head around his door, eyes sparkling.

"We are ready for you now." He told the warlock quietly.

Taking a deep breath, Merlin ducked inside the office, lowering his eyes and trundling uneasily. He immediately felt several pairs of eyes on him and blushed. He looked up and instantly wanted to glance downwards at his feet again; he wasn't used to so much attention, and certainly didn't like it. Harry, Hermione and Ron had been quarrelling it seemed, along with Luna and Neville. Even Fred and George were there, dressed in quite smart clothes, with pockets full of their stuff from their joke shop; it seemed as though their parents had explained who Merlin was, because they were staring at him in awe. Remus Lupin, as well as both Molly and Arthur Weasley were standing in the corner, observing, while Mad-Eye Moody and Professor McGonagall looked on. Merlin was stunned to find that Sirius Black was among them, looking healthy and lively.

"Good morning." Mad-Eye growled. "I trust you slept well?"

"Oh, don't be so hard on him, Mad-Eye." Molly scolded him, though it was half-hearted. She turned back to Merlin and gazed at him kindly. "I hope you're feeling better, dear. That was a very nasty wound."

"T-thanks?" Merlin stammered, unsure.

"I suppose I should be the one thanking you." Sirius said sincerely, stepping forwards, his arms crossed tightly across his chest. "It has come to my understanding that you brought me back from the dead."

"Well… it wasn't really like that…" Merlin stuttered, his cobalt eyes shadowed.

"You may have forgotten, but we do know who you are." Lupin reminded him, raising an eyebrow.

"Yes." Merlin admitted. "But bringing people back to life is complicated."

"You brought my godfather back to life." Harry spoke up. There was no resent in his voice, just pure gratitude. "Thank you."

Merlin quickly countered, "It was no trouble."

"You collapsed afterwards." Hermione pointed out shortly. It was hard to sense whether or not she was annoyed, afraid, or awed.

"Occupational hazard." Merlin replied smoothly.

Harry shuffled forwards. "Look… Merlin." He said, saying Merlin's name out loud for the first time in the room. Merlin flinched visibly while the others coughed and kicked the ground. "I really appreciate what you did to save my godfather. No matter what the others think… I trust you."

Merlin beamed. "Thanks, Harry."

"I trust you too!" Ginny piped up.

"And me." Ron added.

"And me." Hermione seconded.

"I'm grateful, really." Merlin told them thankfully, relieved. "For over five hundred years I've been hiding… okay, so maybe from execution for the first two hundred… but I'm glad I don't have to hide any more." He turned to Harry seriously. "I fulfilled my destiny when I helped Arthur create Albion… now it's time for me to help you with yours."

"I have a… destiny?" Harry asked, confused.

Merlin turned to Dumbledore, shooting him an accusing look. "You didn't tell him?"

"It was not yet the right time." Dumbledore answered smoothly.

Merlin scowled inwardly. This was just like his situation with Arthur… He wheeled back to Harry and quickly explained; "You are destined to defeat Voldemort and bring peace among all magic and non-magic users. I'm supposed to help you and restore the Ways of the Old Religion afterwards, with your help."

"I…" Harry looked lost for words. "I don't know what to say."

"I'm guessing Dumbledore has told you about the prophecy?"

Harry nodded. "What's that got to do with it?"

"Everything." Was Merlin's reply.

The warlock spent the rest of the day explaining the links of the prophecy to his destiny to Harry and speaking to the members of the Order about his past and his years serving Arthur in Camelot. Most of them were shocked when they discovered Merlin's losses and felt much sympathy for him, but the warlock waved it away, stating that it was all in the past, although it stung him viciously to be reliving his tales of his time with Arthur, Gwen, Gaius and the Knights of the Round Table.

Fred and George were able to lighten the mood though: "You were King Arthur's servant?"

"Yep." Merlin laughed. "The one and only."

"What, so you had to do chores and stuff?" Fred asked, disbelievingly.

Merlin laughed again. "Yes. I had to clean Arthur's chambers, dress him each morning, undress him each evening, serve him breakfast, lunch and dinner, prepare him baths, clean his armour and sword, go with him on daft quests and stupid patrols and also muck out the stables. And also you have to add the fact that I saved his bloody life every week for no extra charge and got terrible wages, and also got myself injured weekly for him, to save his royal arse. Believe me, that wound I got earlier is a pinprick compared to what I've had to cope with. Cross bow wounds hurt."

That evening, the rest of the Order pledged their alliances with Merlin, promising to keep his secret hidden. Merlin, meanwhile, would stay in the chambers of the House of Pendragon until the school year ended, which was in a few days time. It seemed that all the Order and DA members who knew about him were treating him like a hero, with the greatest respect.

When night began to fall, Merlin wished the Order and the members of the DA good night and then began making his way to his chambers in the darkness. He reached his new chambers and locked himself inside, relieved but exhausted. Merlin was ecstatic that they had accepted him for who he was – it was as if his dreams had come to life. He suddenly found himself wishing that Arthur had been as calm when he had found out that his manservant was a sorcerer. When Arthur had yelled at him to get away, with fear, terror and betrayal in his eyes, it had torn Merlin apart.

He found himself remembering Arthur when he looked around the chambers of the House of Pendragon. These chambers looked remarkably like Arthur's. Sighing, memories clouding his mind, Merlin clambered into bed and lay, motionless, under the duvet.

Pushing away thoughts of Camlann and Camelot, Merlin slipped into a deep, dreamless sleep.
