(A/N: Hi guys! So I've started my Merlin fic. I'm sorry I haven't updated my minewt fic, but I've been really busy and I'm having writers block for that story. I changed my username because I thought it might be best for a writer to have a grammatically correct username haha. I hope to update at least once more this week and it will probably happen because it's a billion degrees out and I don't have air conditioning in my house, but the library does have ac. I had to rewatch the ending to write this so I hope you like it. Reviews make my day!)

EVERYTHING BELONGS TO BBC AND SHINE I OWN NOTHING!

"No man, no matter how great, can control his destiny."

Merlin had heard Kilgharrah speak those words twice now. The first time was on his way to Camelot he thought he heard someone say it. He didn't realize that it was The Great Dragon who had said it until he heard it a second time when Arthur was dying. He thought he had known his destiny, but once Arthur died, he didn't know anymore. Nobody, not even Kilgharrah, realized that his destiny was not supposed to happen in the 9th century, but in the 21st century. However, Merlin had to live the 1500 years in between the two time periods.

After Arthur's death, Merlin returned to live with Gaius. He tried to spend time with Percival, because Percival was devastated over Gwaine's death. Percival and Gwaine had been together, just like Merlin and Arthur had. However, after Gaius died about five years after Arthur, the memories of Camelot became too much and he left to go back to Ealdor and live with his mother. He stayed there for about 15 more years, during which he realized that he wasn't aging. His mother helped him get over Arthur's death, but she eventually became old and passed away. Merlin was devastated over his mother's death, so he left Ealdor to use magic and build a little cottage near Avalon.

Throughout the years, Merlin witnessed many things. He realized that he could not die, and he didn't age. The only way he could look his age was if he used a spell. He still wasn't happy, but he was willing to go through everything if it meant seeing Arthur again. He saw Camelot fall when William the Conqueror took over the United Kingdom in 1066. He witnessed magic wands come to be popular, and he helped with the building of Hogwarts when he was about 200 years old. He became good friends with Salazar Slytherin, although he didn't agree with his pure blooded status. Merlin became the first person sorted into the Slytherin house and saw magic form a government. He decided that he would start the Order of Merlin, where he would pick a witch or wizard who he found outstanding, and give them a reward.

Merlin did not just stay in the wizarding world. Muggles always reminded him of his time in Camelot, so he stayed with the muggles. While out of the wizarding world, he meat Rory Williams, who had been waiting for his wife, Amy, to wake up for a good 400 years before Merlin was even born. Rory helped keep Merlin out of trouble and away from drugs. Rory became Merlin's first friend since losing Camelot.

Rory introduced Merlin to the Eleventh Doctor about 100 years after they met, but Merlin met the Ninth Doctor a few years later, and realized that Nine was the easiest for him to get along with. He was friends all regenerations with the Doctor, and the Doctor would come visit him every so often throughout history.

Merlin met Captain Jack Harkness in a tavern one evening. Jack had flirted with him and bought him drinks. Neither of them mentioned that they were immortal, so they continued on with their lives. Every couple of centuries, they would find each other again. After meeting 5 times over a span of 400 years and neither of them looking any different, they realized both were immortal and spent more time together.

In the 15th century, Merlin strayed away from muggles completely. Muggles had become fearful of magic, and had started to burn anyone suspected of sorcery. It was like Uther's rule all over again,except this time there was no Once and Future Prince to protect. He left England and moved to France. Without any of his immortal friends to keep him sane, he fell into drugs and alcohol. He didn't know how to deal with the pain of losing everything and the human brain is not supposed to have memories of almost a thousand years. He began spiraling down into a pit of insanity that he never fully recovered from.

Thankfully, the French Ministry of Magic found him and decided to bring him to Beauxbatons School of Magic to help get some structure and sanity back into his life. While he was there, he met Nicholas and Perenelle Flamel. They were alchemists, who were trying to create the Philosopher's Stone. At first he was angry with them and tried to convince them that immortality was the worst thing that could happen to a person, but they did not listen. They decided to become immortal to help get Merlin back onto his feet and prepare for Arthur's return. The nightmares and insanity never fully went away, but Nicholas and Perenelle convinced him to use the knowledge Gaius had given him and become a physician, which helped. Eventually the three of them moved back to Merlin's cottage by Avalon and with the help of the Flamels and the Philosopher's Stone, they opened Albion Hospital.

Merlin watched oceans rise and empires fall (Hamilton anyone?). He saw crusades and world wars and people be downright horrible to each other, yet still Arthur did not return. In 1991, Harry Potter destroyed the Philosopher's Stone. Merlin wanted to be angry at Harry Potter for destroying Nicholas and Perenelle's immortality, but how could he when Harry was just an eleven year old trying to stop the man who had killed his parents? When he asked Nicholas what they would do, Nicholas said that their immortality would no longer be needed, as Arthur was soon to return. Merlin had no idea how this was true, but he dared, if even slightly, to hope it was true. A few years later, he fought alongside Harry Potter in the Battle of Hogwarts. Harry found out that Merlin was actually alive and responded with "Merlin's pants!" which caused Merlin to laugh harder than he had in centuries.

One day, Merlin was working in the hospital when he heard a voice that he hadn't heard since the day Arthur died. "Take heed, for when Albion's need is greatest, Arthur will rise again."

It had been one of the last things Kilgharrah had said to him. He felt magic swirling around him. He knew. For the first time in centuries, he was sure of one thing. Arthur had returned.
