So... ah... yes, I'm trying this. First HTTYD fanfic... I'm probably going to suck. There may be some misspelled things (though I'm very good at spelling) and, ah, odd Viking lingo and accents... Yeah... Heh, this'll be interesting. HiccupXAstrid TuffnutXOC and if you squint real hard you'll see a little bit of FishlegsXRuffnut.

Disclaimer: I do not own HTTYD, it is not mine. I do not have a Night Fury hiding in my backyard, that is simply an... illusion...

It was a dark and stormy day. No one was out flying, it was simply too dangerous. Yet, somehow, people claimed that the clouds looked stirred up by wings. It wasn't until the signature Night Fury fire ball came through the clouds and it the center of town square, like a sign for help. When Hiccup saw this, first he went up to his room and checked that Toothless was still there, still asleep, before going down to his father, Stoick.

"Er, Dad?" "What is it Hiccup?" "Er… I think I saw something outside." "What now Hiccup? Let me guess, another Night Fury?" "Yes."

Stoick nearly fell off of his stool, "What?" he spluttered. He paled. "That's… no Night Fury would be doin' that, not in this weather, unless they were being forced! We ought to see what's goin' on!"

They went outside, Toothless appeared and followed. It was dark, and there was lightning and a drizzle, but they could make out a dark shape flying in the clouds.

Astrid appeared by Hiccup's side, "Oh, that isn't you? I thought you might be doing something stupid again. So… who's that then?" Just then they saw something dive out of the clouds, leaving a shriek in its wake. It kept getting closer, and closer, until it crashed into the ground.

It was indeed a Night Fury, and it did have a rider. But the person was so covered in mud and, now, blood, they couldn't be made out. But Stoick plowed through, and gently lifted the figure. The Night Fury growled faintly, but seemed too weak to move.

Fishlegs had appeared as well, and he whispered, "Doesn't that seem like Toothless? I mean, duh, it's a Night Fury, but it also seems protective of that person. Weird, huh?" But then Stoick spoke.

"I'd know this face anywhere! It's… it's Shard!" Shard. Hiccup had heard that name before; his father mentioned it on occasion. She was some girl who was abducted at a young age, they said, during a battle with dragons. None of the teenagers really knew who she was; their parents wouldn't talk about it.

Hiccup walked up to his father, Toothless following. Toothless went over to the other Night Fury, looking at it nervously. Whether he was afraid of it, or worried for it, Hiccup couldn't tell. He looked at the figure in his father's large arms.

It was a girl, who he'd put at about his age or maybe a bit younger. She had dark red hair, tied back in a ponytail instead of braided, it had some lighter, brighter, streaks of red, and it was wavy and would be rather pretty if it was not matted with filth and blood. Her eyes were narrow slits, as if she was still in shock and her brain was still settling into unconsciousness, but the green of them still showed. She was very skinny, like she was underfed, and she seemed to be short, for whatever age she was. However, she did have some lean and well-toned muscles. She was scrawny, yet strong.

Astrid came up, as well as Fishlegs, Tuffnut, Ruffnut, and Snotlout. Astrid looked up at Stoick, and whispered, "She could stay at my place." She seemed to think that, as none of the adults had come forward to claim Shard as their daughter, they might be away or… dead. But Stoick's reply had an underlying tone of harshness, "No. She's staying with us."

Hiccup knew by 'us' he had meant him. When they turned to leave, he whispered to Toothless, "Take care of friend, okay bud?" Toothless made eye contact with him and looked back at the Night Fury, showing he understood.

So, they went back to their home, and Hiccup followed his father through a few corridors he didn't recognize completely. Finally they came into a room he had never been in before. Actually, it looked a lot like his, with similar furnishings, including a bed. He didn't completely understand why they had this room, perhaps it was for people who visited Berk and needed a place to stay? That was very, very unlikely.

Stoick laid the fragile girl down on the bed, carefully as not to smear any blood. "So… Dad… why do we have this room and who exactly is Shard?" Stoick eyed him carefully, as if wary.

He sighed, "Okay, where do I start? Well, this room was built for Shard. You see… she's your sister… your younger twin, specific'ly. When you two were abo'… three or four years ol'… a battle with the dragons was particularly fierce. Your mother and I… we were out at the time, see? With you and Shard. The attack came suddenly. We – all of us were separated. But your mother and I kept an eye on you two; we jus'… jus' got carried away… We looked up in time to see the shadow of a dragon flyin' away, little Shard clutched in its jaws… we were sure we'd never see 'er again. Bu'… here's livin' proof we were wrong. D'you… d'you mind keepin' an eye on her Hiccup?"

Hiccup looked at the injured girl on the bed, and suddenly felt a sense of… protectiveness, like the way he sometimes felt with Toothless, "Yeah, sure, Dad."

As Stoick left, Hiccup called out to him, "You know… by the looks of it, she's a hiccup too. And yet, I'm named 'Hiccup'?"

His father smiled at him, "Well… I named your sister… I'm not sure what your mother had in mind namin' you, but to her you were her sweet little Hiccup. An' I reckon Shard was a bit stronger than you when you were little."

And he left, leaving Hiccup alone with his newly discovered twin. He looked at his sister, who looked like she could be a few years younger than what she apparently was, and how frail she seemed. What exactly had happened to Shard? How had she managed to survive after being taken by a dragon, and what dragon had taken her? There was so much he wanted to ask her, especially about her own Night Fury. She seemed, before she crashed, just as at ease with it as he was with Toothless. And her Night Fury reacted in a protective way that, which Fishlegs had pointed out, was an awful lot like Toothless. And, sure, she did look a little like him… she was… cute. He hoped that she could get better soon.

New Night Fury, Hiccup's twin, what could go wrong? Heheh... oh, you'll find out.
