I recently went to see the second How To Train Your Dragon movie, and since I've been reading a lot of Harry Potter recently I thought it would be interesting to do a crossover. I tried to take a unique view towards it, hopefully something that hasn't already been done! This ins't really a chapter of its own, but a good prologue always helps a story along.

Disclaimer: I do not own How To Train Your Dragon or Harry Potter.

The house lay quiet, and the family within it had no way of knowing the events that would soon occur. Outside, children roamed the streets trick-or-treating, similarly unaware of even the existence of the house in which this family lived.

You've probably hear this story before, haven't you? Ah, yet I doubt you've heard this version of it.

A cloak dragged on the pavement and leaves outside, pausing at the gate of the house and looking straight at it. It was only recently that he had been enabled to see it, and he was about to make good use of it. The silly man the family had chosen as their secret keeper had turned against them far too easily, tired of being the butt of jokes and taunts, eager for fame and very easily drawn in with promises of glory in battle and riches in the new society.

He actually thought that he was trusted. How quaint. But no matter, the man would see his own folly soon enough.

The gate creaked open, unused for some time, and the man stepped past and made his way to the door across a yard bigger than expected, for a family that nearly never left the house. A simple unlocking charm - something any first year could do, were they really so stupid? - took care of the door, and as he stepped across the threshold James Potter burst into the entryway, shouting at his wife.

"Lily, it's him! Go, protect Harry, I'll hold him off!"

Without a wand? Lord Voldemort didn't deign to take even a second to laugh, and felled James where he stood. There was a bright flash of green which illuminated everything in the entryway for a split second and the black-haired man fell to the ground, eyes glassy and staring like a puppet whose strings had been cut and was left alone on the stage. Voldemort stepped over him disdainfully and proceeded up the stairs.

He could hear banging and rustling coming from a room at the end of the hall - presumably the Mudblood was desperately trying to defend herself by blocking the door. How naive of her. Voldemort strode towards the door and raised his wand, a Blasting Curse on his lips.

The door did not budge.

He frowned, and flicked his wand to render visible the spell which Lily Potter had used to block the door. His eyes traced the light of the spell and his wand twitched in his hand. So the Mudblood wanted to play, did she? Well, she would get her wish.

Inside the nursery, Lily Potter was frantically working, drawing sigils on the carpet underneath Harry's crib to synchronize with the circle she'd already painted there, in the underside, in case this situation ever came about. She was on the verge of sobbing, knowing from the shout and the crash from below that her husband was no doubt dead. As she finished, she stood and painted a single rune on her son's forehead - Sowlio, the lightning bolt, the rune of guidance who would take her Harry somewhere safe.

"Mummy loves you, Harry," she said, her voice breaking on the last word. "Mummy and Daddy both love you very much and you must remember that, no matter what, okay?" She kissed his cheek and placed his back in the crib, Harry looking up at her in confusion. Lily began waving and flicking her wand, the circle and runes powering a complex enchantment which enraptured Harry as it was woven around his crib. It took moments to finish - she had planned this out far in advance - and Lily whirled around as her enchantment on the door splintered, along with the door itself, and Voldemort came through.

"Not Harry, please, not Harry-"

"Stand aside, you silly girl-"

"Not Harry, please, don't hurt him-"

"Stand aside, I said-"

"Please, not my son-"

"Stand aside!" Voldemort cast aside any thought of sparing her, nevermind what Severus wanted. The yew wand flashed, white in the light of the nursery, and Lily Potter fell with a scream beside the crib.

Harry was not crying as Voldemort approached him. The Dark Lord regarded him with something similar to contempt, his red eyes flashing.

"So," he said quietly. "You are to be my downfall."

Harry only stared back, silent, and the painted rune hidden under dark brown bangs.

"Let us see you try, when you are dead," Voldemort hissed, and the yew wand flashed one final time and the nursery erupted into chaos.

From the outside, as the force of the explosion felled the Fidelius around the house, the Muggles in the area turned sharply towards the noise from a building they did not remember. Several called the police, but the house would be forgotten again soon enough, once the wizards arrived on the scene.

The rune circle under Harry's crib had exploded the moment the last syllable left the Dark Lord's lips, a dome of pure blue energy shooting up around Harry's crib to cover him, which reflected the spell into Voldemort's horrified face. He screamed, collapsing and disintegrating, but the spell was not yet done. Lily had created something to take her son away from danger, and the spell performed exactly as expected. There was one aspect, however, that Lily had not compensated for or even taken into account. The power of the killing curse had struck the shield and left a mark, ever-so-slightly skewing the spell, and when Harry was taken somewhere safe it was not to the intended destination, or even the intended time.

Hagrid arrived on the scene to find a distraught Sirius Black crouching in the ashes of his best friend's home. As he approached, the wizard stood and disapparated on the spot. Hagrid made no move to stop him - even if he could have, who was he to interrupt the man's mourning? Hagrid crunched over rubble and, nervously, made his way up partially-destroyed stairs and into the nursery.

What he saw there shocked him. There was no one there, living or dead. Professor Dumbledore had told him that there was a possibility Harry was alive, but he hadn't told Hagrid what to do if someone had taken the baby boy from the house, for what else could have happened? It wasn't as though Harry was able to crawl away.

Hagrid left in a hurry. Dumbledore would want to know about this.
