Prologue

Authors Note: Hi guys! So, yet another story, huh? Sorry, but it does make writing a LOT easier :) Please don't mind any spelling and/or grammar errors, as am currently unbeta'd. SLOW UPDATEDS! Pairings are mostly yet to be decided, but there WILL be slash, so if you don't like it, please don't read, you have been warned! Will be slow-burn-ish, due to character ages. I, personally, find this idea of Merlin and/or Arthur teaching at Hogwarts really really fun! This story is rated M. Comments will be welcomed, but please no flames!

Disclaimer: Harry Potter, Merlin and their characters do not belong to me, sadly.

The first to hear the call was a small, white dragon, currently keeping an eye on the happenings of Britain. At the time, she was masquerading as a cat, living with a lovely wizarding family in Godric's Hollow – the ideal place to keep up with the news. Or at least, she had been.

The lovely family had been killed during the night while she'd been out hunting, and the toddler kidnapped! And so, she set out, first to check on the toddler, then to gain more information on what had happened – something wasn't right.

The second to respond was a large, golden dragon. This dragon was much, much older and wiser than the white one, and immediately set off for Britain, having spent the last hundred years or so at the Romanian Dragon Reserve, amusing himself by watching the humans, and teaching the younger dragons the finer points of Riddles. But now, it would seem, his presence was required back in Britain.

Across the pond, two journalists shot out of bed, startled.

"What the hell was that?!" the blond demanded, whirling towards the window. When no answer was forthcoming, he spun back towards his raven-haired partner. "Merlin..." he began, only to falter.

His companion was crumpled on the floor, clutching his head.

"MERLIN!" Arthur scrambled over the bed, dropping down beside the raven and pulling him close, his eyes darting round the room, searching for the threat.

"'thur?" Merlin groaned, causing Arthur to hum softly, prying Merlin's hands from his head.

"Shh, it's ok, you're safe," Arthur murmured, stroking a hand through Merlin's hair gently. "Whatever it was, seems to have gone."

"No'atak," Merlin managed, his eyes clearing.

"Huh? What do you mean, no attack?" Arthur frowned.

Merlin sagged against him weakly.

"Something's happened," he sighed. "That wasn't an attack, it was a Call."

"A Call?! We haven't had one of those for years! Where are we heading?" Arthur asked, moving to start packing.

"Nowhere." Merlin tightened his grip on Arthur's shirt.

Arthur blinked.

"We're not going? But you just said-"

"I know. Our instructions, for now, are to sit tight, but be ready to move."

"Oh, ok. And where would we be heading?" Arthur raised his eyebrow.

"Britain. I'll speak to work, get us moved departments – not entirely sure – how long we've got." Merlin shrugged.

Arthur sighed.

"Here we go again..."
