Dagur the Destroyer
This is Starring Astrid not Hiccup. Also not a pairing of them. At least it won't be the main plot. Or it might be part of the plot. I don't know yet. Also the kids are eighteen-ish now.
Astrid Hofferson stepped out into the waning sunlight for the first time in a week. Her dragon, Stormfly, had been killed in a raid by the Beserker tribe and she had been overwhelmed by sadness.
Her friends were all gathered outside waiting for her. Even Snotlout wasn't making comments. Hiccup came forward and placed his hand on the girl's shoulder.
"Astrid…" He started but she brushed his hand away and climbed up past the chief's house to where the others had made a grave for Stormfly.
It wasn't traditional for a grave to be made on Berk. But this was the way that they had wanted it done so that everyone could remember the dragon.
Astrid felt the tears in her eyes but brushed them away.
"Hi girl… you would laugh if you could see me right now wouldn't you? I'm sorry. It's my fault that you died, I made a bad call." The blonde teen said.
"I'll never forget you girl. You will always my best friend." Astrid said breaking down into tears.
Toothless, who had been sitting on top of Hiccup's house noticed Astrid and hopped down next to her. She scratched his head affectionately and he made his usual purring noise.
Then a sound rang out across the island. A distinct instantly recognizable sound. High pitched super fast whistling.
"NIGHT FURY!" A villager yelled.
Astrid and Toothless looked up into the sky to see a black shape slam into the top of the rocky spire then spiral down into the woods. Astrid leaped onto Toothless' back and took off.
"Lets go see what that was Toothless!" Astrid yelled.
"Astrid no! There's a storm coming in!" Hiccup yelled but his voice was lost in the wind.
Astrid and Toothless were close to where the dragon had gone down when the storm reached Berk. Toothless was pushed around by the wind and a particularly strong gust forced him onto the ground.
Astrid slid down from the saddle and the two walked through the woods as the wind howled over their heads. Astrid stopped as Toothless made his signature purring noise.
The Viking turned to see him looking up at a splintered tree. She followed the path made by the broken branches and stopped so suddenly that Toothless bumped into her.
Lying before her was another night fury. The dragon noticed her and rolled onto its feet but stumbled forward. The girl looked at it confused but quickly found the problem. Its right front leg had been severed at the shoulder joint. And something had sealed the wound as it was cutting.
"Hey there… its okay. I won't hurt you." Astrid said walking slowly forward a hand outstretched.
The dragon growled and backed away then flinched as lightning flashed across the sky. Toothless growled at the sky and stood next to Astrid defensively.
"Toothless what's wrong?" She asked then she could hear what had him angry.
A roar that belonged to only one dragon. The Skrill.
Berk
"Fishlegs I'm worried that she might be in trouble." Hiccup said for the tenth time.
"I know but we can't fly in this weather. It's to windy." The large boy said.
A faint echo reached the village just then and Hiccup straightened.
"I know that roar. It's the Skrill." He said.
"That's impossible. You froze it remember?" Fishlegs asked jokingly.
"As if that's the only Skrill. Remember what the book said? Skrill only appear during thunder storms."
"Still we can't do anything about it! It's to windy for any dragon to fly!"
"What if we dug?" Hiccup asked with a gleam in his eye.
Back to Astrid…
"Where is it Toothless?" Astrid asked drawing her axe.
The dragon pointed out a spot in the sky with his nose. It was faint but she could definitely make out the shape of a dragon.
"We should hide. Without Hiccup you can't fly as fast as that thing. Come on Toothless." Astrid said.
He started making a path through the forest while Astrid tried to coax the injured Night Fury to follow them. The dragon was more subdued now that lightning was constantly crackling in the sky. It hobbled after the girl slowly and she made sure Toothless stayed close.
Nearly ten minutes later Toothless had found one of the old Whispering Death caves and led the Viking and the Dragon inside.
"I found you!" An all too familiar maniacal voice yelled.
Astrid turned to see the Skrill flying towards them with Dagur the deranged on its back. The Viking turned to see the night fury still hobbling into the cave.
"Dagur! What have you done?!" Astrid yelled brandishing her axe.
"I've done what Hiccup couldn't. I've tamed a Skrill. Meet Thunder Wing." He said patting the dragon on its snout.
"I promised Stormfly that I'd avenge her! I can't think of any better time!" Astrid yelled stalling for time.
"Oh yes! You little girl are going to kill me and my Skrill? I believe that I alone was enough for your dragon." Dagur said mockingly.
"All of Berk will come to destroy you if you kill me! You can't win here, just leave!" Astrid yelled.
"Or I could kill you then wipe out Berk with my fleet. You lose Astrid." He said as the Skrill charged up a lighting blast.
Astrid ran inside the cave and threw her axe in the air. The Skrill let loose its lightning but the electricity went towards the axe and hit the cave entrance collapsing it.
Dagur considered making sure the girl was dead but noticed a line approaching him on the ground.
"Oh hiccup. What I wouldn't give to see your face when you find her." Dagur said as he turned to fly away.
Then his Dragon stopped as a volley of spikes flew past its face. There riding a Whispering Death was Hiccup.
"What have you done with Astrid, Dagur?" The boy asked.
"Oh look behind you. Now I've killed your Night Fury and your girlfriend. I'll be back for you Hiccup." Dagur said flying away into the clouds.
Hiccup turned to the collapsed cave and patted the Whispering Death on its spiky head.
"Okay Shredder, clear away that rubble. I'll give you an extra helping of fish." He said.
The dragon spun its teeth and started chewing through the rock at high speed.
Inside the cave Toothless was nudging Astrid. She wasn't moving and the dragon was worried that she might be dead. Then she coughed and he nudged her face.
"Hi Toothless. AHHHHHH my arm! Why does it hurt so bad?!" She cried.
Toothless shot a plasma blast at the wall and lit up the cave. Astrid looked over at her arm and realized why it hurt so much. It was gone.
One of the rocks had landed on her arm and crushed everything up to the shoulder it was now less an arm than a stump of a shoulder.
Tears welled up in her eyes. That was her right arm, the one she used all the time and now it was gone. She covered her face in her remaining hand and cried.
That's how Hiccup and Shredder found her minutes later.
