And now we are into the Riders of Berk season finale. It all begins here. This will cover the season one finale and go through Defenders of Berk. After that, there will be another crossover, but I'm not telling you what HTTYD will be crossed with. You're very welcome to guess what it is in your reviews or PMs. I'll tell you this; it's not going to be an easy guess. For now, I am giving you the first chapter and I might post the second chapter because I am going on vacation and won't post again until the middle of next week because I won't be able to access Fan Fiction or my email unless my friends is nice and let's me use her smartphone. The reviews will be comforting while I'm smearing aloe on my sunburn.

It had been several weeks since the Vikings had returned to the Berk after the death of the Scottish Death. Things had been quiet compared to what they had experienced.

The Haddock family had grown a little on their return. It was now Stoick, Hiccup, and Grim, along with their dragons, Thornado, Toothless, Deathshriek, and the newest member, Fearcloak, a Creeping Shadow dragon from Scotland. Fishlegs had originally brought the little wounded dragon back with him to study and keep as a companion to Meatlug, Fearcloak wanted none of that. He certainly liked Fishlegs and Meatlug, but he liked Grim more. The dragon speaker quickly learned the little dragon wasn't going anywhere without him and made a place in the house for him.

Grim and Deathshriek flew around the island. They were preparing for Bork Week, the creator of the Book of Dragons. The others were working on their dragon calls in the forest. Grim did not need to practice since he had mastered Dragonese in several dialects.

The dark blue and black Baleful Banshee soared through the air just as gracefully as Toothless, due to their physical similarities. Deathshriek was only a little larger and colored differently, much like his rider was from Hiccup. Grim's hair was dark and shaggy, contrasting sharply with his pale features and pure blue eyes.

For Bork Week, Stoick wanted to have an air show. It was the first year that Vikings and dragons were at peace. Grim had taken it upon himself to plan the flight around the village. The different dragons would be showing off different formations. Grim and Deathshriek flew around the suggested flight path to see if it would work out.

A small screech caught Grim's attention as they flew. He turned to see Fearcloak flapping his wings furiously to keep up with Deathshriek.

"Fearcloak, what are you doing out here?" Grim asked.

The Creeping Shadow caught up to Deathshriek and grabbed onto the blue and black hide with his wings. "I didn't want to be at the house by myself. Stoick and Thornado left and Hiccup and Toothless are at dragon training."

"You could have gone with them," said Grim.

Creeping Shadows had thin bodies about three feet long, two long tails, narrow heads with four red eyes, and strong black wings that were double the length of their bodies. They walked on their feet and wings, like Nightmares. Fearcloak crawled across Deathshriek's back to Grim and climbed up on Grim's back, easily gripping the dark blue and black shirt made out of dragon scales.

"I want to go with you," said Fearcloak, arranging his wings to hold on with his tiny wing claws to Grim's shoulders. It was one of Fearcloak's favorite things to do. Ever since his wing was healed enough, he clung to trees, walls, and people, especially Grim. It was how he earned his name. When Fearcloak hung off Grim's shoulders, tucking his head, he looked like an old, ragged cloak.

"We won't be up here for much longer," said Grim. "Deathshriek, let's do one more path and then we'll go find the riders."

"All right, Grim," Deathshriek said.

After flying one more path, they searched for the others. Deathshriek found Hiccup and Toothless first and turned to land next to them. Astrid was also there with Stormfly. She and Hiccup were talking about something. Hiccup seemed upset by it.

"Am I interrupting something?" Grim asked.

"No," said Hiccup.

"What is wrong?" Grim asked.

Astrid gave an aggravated sigh. "Snotlout opened his mouth."

Deathshriek let out a groan. "What foul stench came out of the fool's mouth this time?"

Grim chuckled.

Astrid frowned. "What did he say?"

"'What foul stench came out of the fool's mouth this time?'" Grim repeated. Seeing Astrid and Hiccup were still a little confused, he elaborated. "The saying comes from when foolish dragons eat something they should not have and get sour stomach. It makes their breath foul."

"I thought it always smelt a little foul," said Astrid.

"To us, yes, but that's because of all the fish they eat," Grim said. "To them, it is tolerable. Now, what did Snotlout say?"

"We were talking about the air show," said Astrid. "Snotlout said that Toothless doesn't have anyone to fly with. Hiccup seems to think he's lonely."

Deathshriek scoffed. Grim reached behind him and put his hand on the Baleful Banshee's nose.

"Hiccup," Grim said softly, "Toothless is not unhappy. He is happy with us. He sees us as his family."

Astrid snapped her fingers. "I almost forgot. Your father and Gobber looking for you. Both of you." She climbed up on Stormfly. "They're waiting for you in the great hall. They looked serious." She left.

"Ah, great," Hiccup said. "Happy Bork Week to me."

Grim urged Deathshriek into the sky to follow Astrid. It did not take long before they caught up with her.

"Astrid!"

The blonde looked over her shoulder. "Grim, what's going on? Stoick and Gobber are waiting for you."

"I wanted to tell you the next time you see Snotlout, tell him he should watch his back," Grim said.

"What are you going to do to him?" asked Astrid.

"Nothing." Grim gave an evil smirk. "But he does not know that."

Astrid mirrored his evil smirk. "No problem."

Deathshriek banked hard, Grim steering him to the village. They landed at the great hall. Toothless was waiting outside and Deathshriek joined him.

"Wait with them," Grim told Fearcloak, pushing off his shoulders.

Hiccup and Grim opened the doors to the great hall. They walked in to see Stoick, Gobber, and other Vikings facing the large table. They turned around as the two came closer.

"Okay, this is weird," said Hiccup.

"Hiccup, Grim, come forward," said Stoick in an authoritative tone.

The two boys stepped forward.

"And hold out your hands, Hiccup," Stoick added.

Hiccup began to hold out his hands, but quickly put them behind his back. "Uh, Dad, Gobber, other scary-looking Vikings? I just want to say, in my own defense, I cannot control Snotlout or the twins twenty-four hours a day."

"This isn't about those jokers, Hiccup," said Gobber. "It's something really good."

Stoick let out an annoyed sigh. "Now then, Hiccup, Grim, as you know Bork Week has begun, the first one since we made peace with the dragons. So it has been decided, from this moment forward, all things dragon related, including Bork's life's work, shall be entrusted to you and the Dragon Academy."

Hiccup's face lit up.

Gobber set a chest on the table. "This is where the Book of Dragons started. Everything he ever wrote on the subject is written in these notes. Personal thoughts, feelings, fears, even some delicious recipes, are all here." He opened the chest to show him the notes.

"Whoa," breathed Hiccup. "I don't know what to say." He looked at Stoick. "Thank you, Dad. This is -."

"Son, this is a big part of our history," said Stoick. "You and the dragons are a big part of our future. It's now up to you to take care of both."

Gobber picked up the chest to hand to Hiccup. Hiccup took it, but Gobber wouldn't give it up.

"Gobber," Stoick said. "Gobber!"

"Right." Gobber let go of the chest, causing Hiccup to stumble back.

Grim quickly reached forward and helped Hiccup get his balance without dropping the chest.

Gobber looked saddened. "They're yours now."

Hiccup turned to the doors to take the chest back to the house.

Grim began to follow. A large hand fell on his shoulder. He stopped and turned to Stoick.

"Grim, this responsibility falls on your shoulders as well," said Stoick. "You are part of this tribe, this family. It would be wrong to exclude you."

Later that night, Hiccup was up late looking at the dragon archives. Grim lay on his bed with Deathshriek curled on his slab next to Toothless' slab.

"Why didn't Bork put this in the Book of Dragons?"

Grim sat up. "How long are you going to be up? I am trying to sleep."

"Sorry," said Hiccup. "But Grim, look. Bork wrote about an island inhabited by Night Furies."

Grim got up. "But he did not put it in the Book of Dragons?"

"It's weird," said Hiccup.

Toothless nudged Hiccup, looking at the pages.

Hiccup put his hand on Toothless' nose. "Toothless, we have to find that island. If we do, we find your family."

Toothless gave a small purr. "I already am home. But I would not mind seeing other Night Furies."

Deathshriek raised his head from the slab. "It would be nice to meet other Night Furies. I have not seen other Baleful Banshees in years."

In the morning, the riders flew off in search of Bork's Cave.

"Let me get this straight," said Snotlout. "To find this island, we have to find Bork's cave?"

"His last known place of residence," Fishlegs corrected.

"Who would live in a cave?" Astrid asked.

"Who wouldn't?" Tuffnut countered.

Grim turned to Astrid. "Astrid, I have lived in a cave."

"But it was out of necessity, wasn't it?" Astrid asked. "You didn't have much of a choice."

Hiccup cut their conversation short. "There must be something in there about the Isle of Night and where we can find it."

"Bork's notes say his cave was cut into the mountains above Odin's Shield," Fishlegs supplied.

They looked ahead and saw an island with lots of mountains.

"Right there," said Hiccup. "This must be it."

They landed.

"Okay, so what are we looking for?" asked Tuffnut.

"It's a cave," Astrid said, annoyed with Tuffnut's stupidity. "Look for a big opening in the side of a mountain."

"Hole, check," said Tuffnut.

"Mountain, on it," said Ruffnut.

Astrid turned to Hiccup. "You know, we don't have to bring them every time."

There was a horrible sound, like a dragon dying. Everyone covered their ears.

Fishlegs and Meatlug flew over to Snotlout and Hookfang.

"What in the world was that?" Fishlegs asked.

"That is a Changewing call, my friend," said Snotlout, leaning his arm on Hookfang's horn. "Surprised you didn't know that."

"I would have if it sounded like one," said Fishlegs. "This is a Changewing." Fishlegs cupped his hands to his mouth and let out a screaming roar.

Snotlout scoffed. "Bet you can't do a Thunder Drum."

"Please," said Fishlegs. "At least challenge me."

Meatlug landed and Fishlegs stood up in the saddle and cleared his throat. He opened his mouth and let out a growling roar.

Everyone covered their ears and yelled at Fishlegs to stop.

"Enough, Fishlegs!" Hiccup yelled over the sound. "That's good."

Fishlegs stopped and looked utterly pleased with himself.

On the other hand, Grim was not. "If you do that again, I will throw you into the ocean," he threatened Fishlegs with a glare.

Fishlegs cowered on Meatlug's back.

Hiccup pointed through the mountains. "Hey, I found an opening."

The space was too narrowed for the most of the dragons to fly through so the dragons walked.

"That Bork was a dweeb," said Snotlout, "but, boy, he could climb like a mountain goat."

There was a loud roar.

Grim whirled around on Deathshriek's back. "Fishlegs, what did I tell you?" he said darkly.

"Actually, that wasn't me," said Fishlegs. "Mine's far more authentic."

There was another loud roar and a purple Thunder Drum flew into view.

"You want to tell that to him!" yelled Astrid.

The dragons took off.

"Head for the cave!" yelled Hiccup.

They flew to where they thought the opening was.

"Wait, what cave?" asked Ruffnut.

"We just saw it!" Astrid cried. "There was a hole!"

"Yeah," said Tuffnut. "Now the hole's gone."

The Thunder Drum dive bombed them.

Hiccup ducked to stay on Toothless. "Snotlout, Ruff, and Tuff, you look for the opening. We'll lure the Thunder Drum away."

They split up.

"Fishlegs, Grim, Thunder Drum call!" Hiccup shouted.

"Wish you would make up your mind," Fishlegs said.

"Fishlegs!" Hiccup yelled, exasperated.

Fishlegs and Grim roared their Thunder Drum calls.

The Thunder Drum turned and started following them.

The twins head-butted the rock face and knocked themselves out.

"It was right here," said Snotlout. He started beating on the rock with his fists. "I swear it was."

There was a growl and a red Changewing appeared beside Snotlout.

Snotlout let out a cry. "Oh, no!"

The Changewing grabbed Snotlout by the behind and flew up with him to the higher rocks.

"Hey! Put me down!" screamed Snotlout. "Hookfang!"

The Monstrous Nightmare flew towards them.

"Way to go, Hookfang!" Snotlout cheered.

Hookfang flew in front of them and lit himself on fire. He breathed fired, just missing Snotlout.

"Go away, Hookfang!" Snotlout ordered.

Hookfang flew away.

The Thunder Drum was chasing Fishlegs and Meatlug in circles. "A little help here!" he yelled to Hiccup, Astrid, and Grim.

The others were sitting on the rocks.

"Go see what you can find," Astrid said to Hiccup and Grim. "We'll keep this guy busy."

"What about Snotlout?" Hiccup asked, pointing at his cousin.

"Not feeling the trust!" they heard him yell faintly.

Astrid and Stormfly flew over to the twins. "Ruff! Tuff!"

"On it," Ruffnut said.

Tuffnut gave Astrid a thumbs-up.

"You're giving me the twins?" Snotlout cried.

The Changewing smacked Snotlout against the side of the cliff repeatedly.

"Okay, I'll take the twins," Snotlout said.

"Go!" yelled Astrid.

Toothless and Deathshriek flew into an opening they found.

"Careful, bud," Hiccup said to Toothless.

They continued back into the darkness.

"Bork's cave," Hiccup said. "This is it."

"We need to hurry," Grim said. "There can be other dragons here."

It was very dark as they continued on. Toothless and Deathshriek landed and their riders jumped off.

"There's got to be something here," said Hiccup.

Toothless lit a fire with a plasma blast.

"Thanks, bud," Hiccup said.

They looked around the cave.

"What is that?" Hiccup muttered.

Grim turned and looked up where Hiccup was looking. On the ceiling of the cave was a crude mural.

"It's a map," whispered Hiccup. "To the Isle of Night! We found it!" He pulled out his notebook and started copying. "I gotta get this down."

There was a large crash and several rocks fell.

"What was that?" Hiccup asked, looking around.

Grim was on high alert.

There was another crash. The fire Toothless lit went out and dust fell from the ceiling. The map cracked and began to fall apart.

"No, no, no, no, no, no!" Hiccup said, trying to get the map copy. "Come on! I need more time."

"We have to go," said Grim. "This whole place is coming down!"

Toothless and Deathshriek covered Hiccup and Grim with their wings. A large rock bounced off Toothless' wing.

"Got it!" said Hiccup.

"Let's go," said Grim.

More rocks came down and blocked the cave entrance.

"So this is just great," Hiccup said, kneeling next to Toothless. "We're trapped and you can't use your shots without bringing the whole ceiling down."

Toothless warbled.

Hiccup turned to Grim. "Can Deathshriek do anything?"

"No," replied Grim. He was looking around frantically. "Deathshriek's fire is not enough to blast the rocks away."

Toothless opened his mouth wide and let out a high-pitched roar.

"Whoa, whoa, whoa!" said Hiccup. "What was that?"

Toothless put his ears up and listened. After tilting his ears several times he put his head between Hiccup's legs and pushed him back in the saddle. He let out the high-pitched roar again.

"Follow me," Toothless said to Deathshriek.

Toothless took to the air. Grim jumped onto Deathshriek's back and held on tightly. Deathshriek followed Toothless, barely being able to see the Night Fury in the dark. The only part of Toothless he could make out was the red in his prosthetic tailfin.

"Where are you going?" Hiccup asked Toothless. "And how are you seeing?"

Toothless continued making the strange roars.

The two dragons rounded a corner and saw sunlight. They flew out of the cave just as the exit caved in.

"Yes!" cheered Hiccup. "We got it. Thanks, bud."

Grim let out a sigh of relief.

They rejoined Astrid and Fishlegs.

"Someone call for backup?" Hiccup asked.

Astrid turned. "Hiccup! Grim! You made it!"

"Please, don't ask me how because I have no idea," Hiccup said.

"We've got this," said Astrid. "Go help Snotlout."

The brothers and their dragons flew over to where the Changewing was cuddling Snotlout on the high rocks. They landed across a gap in the rocks.

The Changewing bent down and grabbed a mouthful of dragon nip, chewed it, and spat it on Snotlout's head.

"Aw," said Hiccup to Snotlout. "You made a new friend."

"Yeah," said Snotlout. "It's not as friendly as it looks."

Toothless flew across the gap and fired a plasma blast.

The Changewing dropped Snotlout off the cliff.

"Hookfang, now!" Grim shouted down to the Nightmare.

Hookfang flew up and caught Snotlout.

"Now that's how you rescue somebody," Snotlout said as Hookfang gained altitude.

"Everything went exactly as we planned," said Tuffnut from the ground.

"Yeah, keep the Changewing busy until Hiccup and Grim show up," Ruffnut said.

They laughed and high-fived.

Astrid turned to Hiccup and Grim. "I still can't believe you survived that cave-in."

"Neither can I," said Hiccup. "I mean, it was all Toothless. He sent out this weird sound, it bounced back towards us, and somehow he used it to find his way out."

Fishlegs and Meatlug flew up beside Astrid and Stormfly.

"I don't get it," said Fishlegs. "How can you use sound to guide you?"

"I do it all the time," Snotlout called from Hookfang as they caught up. "When I hear your voice, I go the other way." He laughed and flew ahead of them.

"So did you find anything?" asked Astrid.

"Only a map," Hiccup said simply, "to the Isle of Night."

"Nice!" said Astrid. "When do we leave?"

"First thing in the morning," Hiccup replied. He rubbed Toothless' head. "By this time tomorrow, bud, you are going to be knee-deep in Night Furies."

Toothless gave a roar and flipped in the air.

In the evening, Hiccup was going over Bork's notes again. Grim was asleep in his bed and Deathshriek was curled on his slab.

"It says there's a reason why there's only Night Furies on that island," said Hiccup.

Toothless came over to him and warbled.

"You guys aren't so friendly with other dragons," said Hiccup.

Toothless let out a louder warble.

"It says, 'Herds of Night Furies can be extremely hostile to other species,'" Hiccup read. He looked up from the notes. "If the other kids come with me on their dragons."

Hiccup closed the journal and got up from his desk. "Well, looks like it's just you and me, bud."

Toothless grunted and looked at Grim and Deathshriek.

"They'll understand," said Hiccup. "Let's go."

Hiccup grabbed his bag, some food, and some water. He glanced over at Grim. "Sorry, Grim."

Hiccup and Toothless left the room.

From his bed, Grim opened one blue eye.

Outside, Hiccup made sure the front door was closed. He climbed up on Toothless' back.

"Well, this is it, Toothless," said Hiccup. "We'll finally get to see you're not alone."

He clicked his prosthetic into the pedal and opened the tailfin. Toothless was in the air with one beat of his wings. They flew over the ocean in the direction the map said to go.

"Next stop the Isle of Night," said Hiccup.

Hiccup and Toothless followed the map to the Isle of Night. "It should take us until morning to reach it." He patted Toothless' head. "You must be excited."

Toothless warbled.

"Give me one good reason why I should not turn back now and tell Stoick what you are doing?"

Hiccup yelped as Grim and Deathshriek appeared beside them. "What if it was your family? Wouldn't you want only a few people there? Besides, Bork wrote that Night Furies are territorial."

"Is that true?" Grim called over to Toothless.

"Yes. You see how protective I am over Hiccup," Toothless replied.

"All right. But you are not going alone," said Grim.

"You can't," said Hiccup. "Night Furies are hostile to other dragon species."

"Hiccup," Grim warned.

Hiccup groaned. "What, are you going to go back and get the others?"

"No, that would a waste of time and energy," Grim answered. He smiled. "The four of us will be fine as long as we stay together."

They flew in silence for a short while.

"You do know Astrid will come after you with her axe for this," Grim said.

Hiccup groaned again. "Ah, great."

They flew all night and in the morning they landed on the Isle of Night.

"If Bork was right, you're going to love this," Hiccup said to Toothless.

"Yes," said Toothless. He bounded forward.

Grim and Deathshriek followed closely behind them.

"Something does not feel right," said Deathshriek.

"What is it?" Grim asked.

"I don't know," Deathshriek answered. "Be on your guard."

Toothless stopped at the top of a large hill.

"Are you ready?" Hiccup asked him.

Toothless warbled the affirmative.

"Okay. Here it goes." Hiccup cupped his hands to his mouth and howled like a Night Fury.

The four of them waited.

A soft roar answered them.

"I can't believe it," said Hiccup.

Toothless let out a cry of his own and was answered once again.

"Hiccup," Grim said quietly. He was beginning to understand what Deathshriek meant.

A black head popped up from the rocks.

"Bork was right!" Hiccup said excitedly. He got off Toothless. "Go get him, Toothless."

Toothless jumped from the hill and turned back to look at Hiccup.

"It's okay," said Hiccup. "Go, go. We're right behind you."

Grim stepped up beside Hiccup. Behind him was Deathshriek.

Toothless made his way over to the dragon, the brothers and Deathshriek finding another way down.

Hiccup, Grim, and Deathshriek kept their distance from Toothless. Toothless was looking for the dragon.

Hiccup looked around. "Something's not right."

"Yeah," said Grim.

Hiccup cupped his hands to his mouth. "Toothless, come back."

Toothless turned around. A bola wrapped around his legs.

"Toothless!" yelled Hiccup, running forward. He was tackled by a large Viking. From behind, he heard Deathshriek roaring and Grim snarling as they wrestled with their own attackers.

Hiccup looked up and saw an unfriendly familiar face. "Alvin."

Two other Outcasts wheeled over a Night Fury decoy.

"Amazingly realistic, wouldn't you say, 'Iccup?" Alvin asked.

"Release us! Now!" snarled Grim.

Deathshriek opened his mouth and screamed, trying to give the others a chance to escape. He was hit in the head by an Outcast with a hammer.

"Deathshriek!" cried Grim.

Toothless struggled and snarled as three Outcasts restrained him.

"Let go of him!" Hiccup ordered, struggling. When he found it was no use, he looked up at Alvin. "What do you want?"

"I want me own dragon trainer," replied Alvin. "And by the looks of it, I've got 'im."

"I am not going to train your dragons, Alvin," Hiccup said.

Alvin chuckled. "I think you will. And once you 'ave, I'll use them to destroy Berk."

"And knowing what you'll do with them, what makes you believe he will train them?" Grim growled.

Alvin turned to Grim. "Oh, 'e does speak. I thought you didn't 'ave a voice of your own, lad. Take 'em!"

The Outcasts yanked Hiccup and Grim to their feet.

"I don't understand," said Hiccup. "How did you do this?"

The Outcasts wrestled the two dragons and resisting riders into a ship. Savage gave Hiccup a good kick and sent him sprawling next to Toothless' head. He stepped aside to reveal an old man and a sheep walking up the gangplank.

"Mildew?" Hiccup asked with a frown. "What are you doing here?"

"Ah, look at you," said Mildew. "The brightest boy on the island and yet, here you are, trapped by a silly old man and his sheep."

"How could you do this?" Hiccup asked, horrified.

"You did it, Hiccup," said Mildew. "You believed our Bork notes, you followed the map we drew you, walked right into our trap, all for the love of a dragon. Maybe you'll think twice next time about where you place your loyalties."

Grim went into a full dragon rage. "You loathsome, guts of an eel traitor!" he roared, fighting against the two Outcasts. "When I get through with you, you evil old man, there will be nothing left for Stoick the Vast to deal with."

Alvin punched Grim across the face. Grim let out a small cry, but silenced himself. Blood dripped down from his nose. Alvin grabbed a fistful of Grim's black hair and yanked him up to look in him the face.

"Never speak that name in front of me again," Alvin said dangerously.

Grim said nothing, but stared at Alvin defiantly.

Alvin threw Grim back on the deck. The Outcast chief laughed evilly. "Raise the sails! We're 'eaded 'ome, to Outcast Island."

Hiccup and Grim looked at Alvin in defiance.

The ship began to sail back to Outcast Island.

Ladies and gentlemen, Grim is angry. This is not going to end well for someone.
