Destiny Is A Scam and So Is This School by GAMERBLADE
Fandoms: Merlin (TV), Harry Potter - J. K. Rowling

Summary
Merlin has survived dragons, destiny, kings, magic-hating monarchs, and the emotional devastation of watching everyone he’s ever loved die.
So really, he thought, a simple trip to the wizarding world for tea couldn’t possibly be that bad.
He was wrong.
Now he’s somehow become the unofficial emotional support adult of Hogwarts, is being hunted by the house-elves because he keeps fixing castle structural problems himself, dealing with a basilisk situation that Merlin is “pretty sure he dealt with once already, back in the 5th century.” and trying to stop Gilderoy Lockhart from deciding that he is his "professional rival."
Merlin regrets stepping outside...

Summary
This is what he’d been waiting for, this is why he’d suffered centuries in an odd sort of stasis. He’d seen the rise and fall of empire after empire, felt spikes in magic and heard whispers of legend that were so close to the real thing he’d nearly deluded himself into believing it time and time again, but nothing had felt quite like this. After an entire millennium of waiting, the King had returned.
Or: Harry Potter is the fated Future King of Camelot and Merlin isn't about to let him grow up in Surrey with no knowledge of magic. What results is a Harry who's much better trained and much more well equipped to dive headfirst into chaos and a Merlin who remembers what it's like to care.

What I Buried To Become Me by Escrovisck

Summary
what i buried to become me
wasn’t pretty, wasn’t clean
it was love i couldn’t carry
and dreams that split at the seams
i’m not proud of every ending
but i’m breathing finally
so don’t ask me to unearth
what i buried to become meFrom the age of one to fourteen, he was loved, hated, targeted, protected, abused, and manipulated. Moved around on the board as a chess piece. Like a pawn. Important, yeah, but disposable. Sacrificial. He wasn't supposed to win the game, he wasn't the one who gave the checkmate at the end.
Harry Potter was a puppet. He was doing what he was supposed to do, following the orders that no one gave to him directly, but that everyone expected him to know either way.
But no more.
His done playing monkey.

(Oh, and enter Sirius Black.)

Summary
Voldemort is not the true danger. Not really.
The real threat is what’s already happened: the Ancient Empires of Magic have fallen, their wisdom forgotten, their wonder reduced to a line in a textbook and bureaucracy. The world has grown smaller. Colder. And Magic—real Magic—is dying.
But not all legacies fade.
Raised in the past by the Founders of Hogwarts, trained by The Emrys himself, Harry returns to the present not just to end a war, but to reclaim a throne long thought lost. He is the Heir to Avalon, The Once and Future King of an empire that the world no longer really remembers.
And the Balance is done waiting.
(A canon-divergent, OP!Harry Merlin xover with mythic rebirth, ancient magic, and one tart-tongued teenager trying to resurrect wonder in a world that no longer believes.)

Summary
Merlin really shouldn’t be surprised anymore.
Whenever his life starts looking like it might be taking a turn for the better, fate finds a way to send him spiralling in another direction with nothing to hold onto. It’s happened more times than Merlin can count, from having to leave Ealdor the first time to freeing Kilgharrah from Camelot’s underground cell. Magic and fate, it seems, are just unable to leave him alone.
So yeah, nothing should really surprise him anymore.
Although he doesn’t see a way anyone could have expected this.
