Summary
Merlin follows Arthur on his quest to the Perilous lands, returning not just with his friend alive and well but also a new kingdom. Magic has lost so much from the purge and the years after and the first rule of magic is that there must be balance, so it gives back. Creating the Kingdom of Oplaria, rled by King Emrys.
But Merlin is not so keen to abandon his destiny and Arthur, he spends his time between the two Kingdoms constantly torn between his friendship with Arthur and his duty to his people and magic. He is good at secret identities after all.
But with Arthur constantly sidelining Merlin how long can he make excuses to stay?
And how much will this change not only the Prophecy but also the future of Albion?This is follows the show from Season 3 episode 8 -> Season 4 episode 7 but will include storylines from other episodes.
If like me you loved all the side characters well then get ready to get a lot more time with them (especially if you love Mithian, Elena and Vivian).

Summary
"I found a baby dragon!”
Arthur rolled his eyes. “A bit early to be drunk, isn’t it Merlin? Dragons have been extinct for centuries.”
Merlin flailed his arms. “That’s what I thought! Well except Kilgharrah of course. But I found one!”
“Excuse me, except who?”
“Kilgharrah.” Merlin said with a very ‘do keep up’ expression, “The dragon who lives in that cave on your family’s estate.”
Or
Merlin finds a baby dragon and Arthur is forced to drive him and the dragon across half the country just to then be faced with another crazy dragon that seems to believe in conspiracy theories. -

Summary
Unsatisfied with his current life, Merlin takes a sabbatical from work and explores the British coastline to clear his head of life's mundaneness. On his return from Cornwall, he comes across a young blonde girl attempting to hitch-hike along the motorway. Fearing for her safety, Merlin offers her a ride home.
Upon entering the small town of Cam-Lott, Merlin makes a lasting impression on Police Chief Arthur Pendranyl and starts a chain of events that have him seeing the inside of a jail cell more often than not. When he isn't being an errand-boy or stumbling upon strange trinkets in forest caves, Merlin slots into the small town life with ease. Between summer faire's, camping trips and hiking, Merlin almost forgets that no one in the town -except one -has left the towns perimeter.
Why has no one left? Why are his memories feeling hazier by the day? And why, oh why, is there a sword buried in a stone?
[Rating will change in later chapters]

Summary
“Merlin was too driven by grief for his other half that he turned back time, but magic like this always has a price. For Merlin to turn back time he had to give up his memories of that time.”
Or, merlin resets time to the day he enters Camelot and meets Arthur and looses his memories, but everyone and I mean EVERYONE remembers the past timeline
Or, the time travel fix it trope but merlin is the only one who doesn’t know about the past lifetime.
(Ignore that Chapter 4 is actually Chapter 3, i’ll fix it when I get the chance.)

Summary
After foolishly seeking shelter in a magical cave, the original Round Table find themselves under a curse tailored to teach each of them a personal lesson. The question is what Merlin is supposed to learn from being turned into a girl, and whether it might not be more of a blessing than a curse, seeing as Gwaine seems rather taken with her new appearance…

Summary
He was about to say some utter bullshit. Arthur could just sense it.
”Arthur” said Merlin, shakily, “I’m pregnant. And it’s yours”
There it was.

Merlin is keeping a secret. No, not the magic. Not the "being in love with Arthur" thing, either. A third, unrelated secret. He could tell Arthur. Or he could fake a pregnancy and rope everyone into gaslighting Arthur. Obvious choice, when you put it like that. Gaslighting it is!
