Ten years ago, the Dragon Knights after failing to capture the Seven Deadly Sins went to check on the Inquisitor. However, when they entered the room they found the Inquisitor dead in the most brutal manner ever for possible.
"Inquisitor Zaratras, this is horrible," said a Dragon Knight.
"How could this have happened to the leader of the Dragon Knights?"
Standing at the doorway was a young Gilthunder, who looked to the Inquisitor's body in horror.
"Father," he gasped.
The Dragon Knights is the noticed Gilthunder standing in the doorway.
"Lord Gilthunder!"
"Please young Master, you mustn't look," said Dragon Knight trying to block his path.
Gilthunder tried to get past them and looked directly at his father. "Who did this? Who killed my father?"
Inquisitor Zaratras was in fact a much older version of Gilthunder, but he was now pinned to the wall by pikes and swords. Blood was pouring out of all the holes in his body and the entire room was filled with gashes and holes that indicated a struggle.
In the present, Gilthunder and a small attachment of soldiers had reached Berina Village in search for Hiccup and the others.
A soldier then approached him. "Sir, it seems he left the village and made his way south west."
"Is that so," said Gilthunder as he turned into that direction. "The Forest of White Dreams lies in that direction."
"Yes, but serve that place is—" Gilthunder ignored him and immediately made his way south west and the soldier and immediately followed him. "Sir Gilthunder!"
'Hiccup,' said Gilthunder to himself.
Meanwhile Hiccup and the others had finally reached the Forest of White Dreams and were making their way through the mist on foot.
"You're sure about this?" Ruffnut. "I mean we've been out here for three hours now, there is no sign of any animals much less any humans."
"She's right," said Ruby and looked back at Hiccup. "Sir Hiccup, do you really think will be able to find one of the Seven Deadly Sins here."
"Probably," said Hiccup.
Tuffnut turned on him. "You mean we came here without any sign of evidence?"
"I've heard is a terrifying monster who lurks around here watching and waiting," said Ruffnut.
Toothless snorted. "Sounds like superstitious nonsense to me."
"And besides I have a little evidence," said Hiccup. "Travelling through the Forest of White Dreams on horseback is more difficult than you think. It is so hard to get your bearings that experience travellers go around it."
"Then this will be the perfect place for someone to hide out," said Ruby.
They kept on walking until something very unusual happened, they soon encountered more than a pair of twins.
"What's going on?" Ruffnut stared.
"There's more than one of me," Tuffnut stared.
Pretty soon all them were talking over one another leaving the rest of the party completely confused.
"Is this the monster of the forest?" Ruby frowned.
"I don't know it looks pretty terrifying to me," said Toothless.
The twins were now fighting with the other twins making it almost impossible to tell which was which.
"Take this you impostor!" said Ruffnut punching one of her clones in the face.
"You're the impostor!" said the Ruffnut duplicate.
"I never knew I was good-looking," said Tuffnut as he wrestled with one of his clones.
"No I'm the good-looking one," said the Tuffnut duplicate.
"How are we going to tell them apart?" Ruby asked.
Hiccup rubbed his chin for a few seconds and a smile appeared on his face. "Hey, guys. I bet you can't mimic Toothless!"
"Yes, we can!" they all yelled.
Immediately all but one pair of the twins transformed into Toothless, but the remaining pair were pretending to be dragons by waving their arms. Hiccup quickly made his move before any of them had a chance to react and drew out a sword from out of nowhere.
He then immediately struck the Toothless imposters and immediately they disappeared in a puff of smoke. Suddenly replacing there were a bunch of imps, short humans with pointy ears which had a tendency of mischievous behaviour.
"Just a bunch of imps," said Toothless as the imps immediately disappeared into the mist. "And people thought they were the monsters of the forest?"
"After them," said Hiccup.
Immediately they began chasing after the imps and Ruby looked at Hiccup. "How do you know they would transform into Toothless?"
"Imps not only transform their appearance, but they mimic the behaviour of the one of one that they impersonate," Hiccup explained. "Fortunately they were mimicking the behaviour of the twins, who aren't exactly the brightest tools in the shed and take everything literally."
"That's true, even the village idiot is smarter than us," Tuffnut nodded.
"And that is saying something," Ruffnut agreed.
Hiccup looked at Ruby and she merely shrugged.
"Let's just focus on chasing after the imps, they're already running to something," said Hiccup.
"Wait, look," Ruby pointed. Soon they could see the shadow of a young girl coming into view from within the mist. "It's a girl."
"You don't think that they're planning to attack her do you?" Tuffnut asked.
"Why else would they be heading towards her?" Ruffnut asked.
"A defenceless little girl like that," said Ruby looking horrified.
"Actually she's not as little as you think," said Toothless as they got closer.
He was right, the girl was anything but small in fact she was a young giant approximately about 30 feet tall.
"Lady Heather!" the imps cried.
"She's big," Tuffnut stared.
"I've never seen a giant before," Ruffnut stared.
"Lady Heather, we accidentally let some Dragon Knights trespassers come in!" one of the imps yelled.
Immediately the giant's eyes open revealing forest green eyes, she then slammed her hand into the ground causing a small earthquake. She then rose to her full height and looked down directly at Hiccup and the others.
Ruby stared at her. "Wait, is she the same giant that—"
The giant immediately narrowed her eyes at them. "Some Dragon Knights got in, huh."
"She is huge," Tuffnut stared with his mouth wide open.
"No, we're not Dragon Knights," said Ruby nervously.
Then suddenly Hiccup vanished into thin air, leaving them bit bewildered about what just happened.
"He's gone?" Ruby blinked.
"Not quite," said Toothless pointing his claw upwards.
That's when they saw the giant was holding hiccup in her right hand. "You're in trouble Dragon Knight," she said fiercely.
"You let go of Sir Hiccup!" Ruby demanded.
The giant blinked and examined him more closely. "Sir Hiccup?"
Hiccup smiled. "Been a long time Heather."
Immediately the giants expressing completely changed. "Captain? It is you!" she said excitedly important closer to her face, rubbing him against her chin.
"Did she just say Captain?" Tuffnut blinked.
"Are you saying that this giant is one of the Seven Deadly Sins?" Ruffnut stared.
Toothless nodded. "Say hello to Heather the Serpent Sin of Envy."
Heather immediately opened her wrist, freeing Hiccup from her grip. "How did you find me?"
Hiccup smiled. "Wasn't looking for you specifically, and just figured that this was the perfect place to hide."
"So you haven't found the others?" Heather asked looking a bit sad.
"No," said Hiccup shaking his head. He then smiled at her sly. "I'm sure that Ragnar is perfectly fine."
Heather huffed. "He better, because of his hanging around with some whore I'm going to kill him." She then looked down at the others. "And who are these guys?"
Ruby immediately looked at her formally. "It's a pleasure to meet you, Lady Heather. I'm Princess Ruby and I am asked Sir Hiccup if he would allow me to travel with him."
Heather looked at Ruby then back to Hiccup. "You know if Astrid suspect that you're involved with this girl, she is going to kill you."
"I assure that that just purely professional," said Hiccup.
"It's better, because you know how angry she gets," Heather warns as she placed him back onto the ground.
Hiccup then began to explain everything and Heather merely listened intently.
"So to finally put an end to all the corruption, and start the Dragon Knights from rampaging, Ruby is trying to get the Seven Deadly Sins together," Hiccup explained.
"Knew things were bad, but I didn't think they were this bad," said Heather.
"We've seen the evidence," said Toothless. "And Dragon Knight Apprentice was willing to kill Ruby."
Heather looked at Ruby curiously. "You certainly must be very brave looking for us."
"Anyway, I'm going to help Ruby gather the Seven Deadly Sins, because I want to find them too," said Hiccup.
Heather raised an eyebrow. "Or one Sin in particular."
The twins looked intrigued by that statement.
"Oooh, dose someone have a lady friend?" Ruffnut asked.
"Is she hot?" Tuffnut asked.
Hiccup narrowed his eyes. "Let's just say that my love life is complicated."
Heather chuckled and she got to her feet. "Guess I'll come along with you, it beats staying here."
Hiccup smiled. "Knew I could count on you."
"Thank you for joining us Lady Heather," said Ruby cheerfully.
"Oh, thank goodness," said an imp looking immensely relieved. "Finally we can live at peace again."
Everyone had completely forgotten about the imps, who were currently hiding behind a rock looking a bit nervous.
"For years she has been threatening us saying that she would make us pay if we didn't give her shelter."
Twins gulped.
"You sure she's not the sin of wraith?" said Ruffnut.
"If she isn't I'd hate to meet the real one," said Tuffnut.
Then suddenly they heard the sound of a raven which immediately caught their attention.
"What was that?" Ruby frowned.
Heather immediately looked around. "This is strange, I thought there weren't any animals left to live down in this bit of the forest."
Toothless sniffed the air. "I definitely smell something."
"Look at that!" Ruffnut pointed.
They immediately looked up into the sky and saw storm clouds gathering above them.
"What's going on?" Tuffnut asked.
"Thunderclouds?" Ruby frowned.
Suddenly a bolt of lightning headed straight down towards them moment it struck the ground Hiccup found himself completely bound by lightning.
"What's this?" he said taking completely by surprise.
"Captain?" Heather gasped.
Seconds later there was another bolt of lightning and the others found themselves similarly bound by lightning.
"My body is gone completely numb," said Ruby.
"I can't move at all," said Toothless.
"What's happening?" Ruffnut asked.
"Talk about bad timing, my nose is itchy," said Tuffnut.
They then heard footsteps and turned and found Gilthunder standing in front of them.
"And you are?" Hiccup asked.
"It would seem as if we meet at last, you Deadly Sins," he said as he approached them.
"This power," Heather stared.
Hiccup nodded. "There's no doubt about it. You're a Dragon Knight aren't you?"
Ruby's eyes widened. "Gilthunder," she gasped. "Gilthunder, is that really you?" Gilthunder merely stood there and remain quiet. "What are you up to? Why are you doing this?"
"So that's him?" said Tuffnut.
"He certainly more handsome than the stories say," said Ruffnut swooning slightly.
"So you know him," said Hiccup.
Ruby nodded. "Oh, yes, since I was a little girl. When he was my father's attendant, and aid to the King and son of the Dragon Knights Inquisitor, he was always at the Palace. So I've kinda grown up with him."
"The son of the Inquisitor, huh?" said Hiccup looking at Gilthunder curiously. "You've certainly grown up since last we met."
Ruby's eyes widened. "What? You know him too?"
Hiccup nodded. "Yeah, I even gave him lessons occasionally when I found myself at the Royal Palace." He then smiled to himself as he looked at Gilthunder. "I barely recognised you, there again I shouldn't be surprised it has been 10 years after all."
"If you have the time to prattle on in this manner, it might be better spent trying to escape those bonds," Gilthunder advised.
"This lightning is definitely familiar," Toothless noted.
"It should," said Hiccup raising an eyebrow at Gilthunder. "We've seen it before when a certain someone locked Berina's water supply and then tried to blow the village away… that was you wasn't it?"
Ruby immediately turned on him. "Sir Hiccup, that can't be! You're wrong, Gilthunder wouldn't—" She stopped when she saw the intense stare coming from his eyes. "No."
"These can't hold me," said Heather as she attempted to break free from her bonds.
"That's useless," said Gilthunder and Heather immediately felt the bond strengthening.
Hiccup looked at her. "Heather just save it, don't bother."
Heather looked at him. "Captain?"
Seconds later, Hiccup found a sword pressing against his neck. Somehow, Gilthunder moved so fast that he reappeared directly behind Hiccup.
"Do you know why the Dragon Knights after the heads of the Seven Deadly Sins?" Gilthunder asked.
"I have theories," said Hiccup looking at him at him with the corner of his eye.
"Half of them are seeking revenge and total eradication of the rebel order that plotted to overthrow the kingdom. The other half wants to do glorious battle and vanquished the legendary warriors to prove their own strength."
Hiccup then gave him an intriguing look. "And which hath you with?"
"Both of them," he said simply. "No, I want more."
Hiccup looked at him in the eyes. "Is that so?"
"Yes, to avenge the death of my father, Zaratras. Dragon Knights Inquisitor. And to show that I'm even greater than he, the most powerful Dragon Knight ever known. Killing you will prove that."
"So you are under the impression that I'm the one who murdered your father, is that it?" Hiccup enquired.
"Are you saying you're not?"
"No."
"He's right," Heather nodded. "The Captain had nothing to do with that."
"Then what happened?" Ruby asked curiously.
"10 years ago we were summoned to the old castle out on the edge of town," said Hiccup.
10 years ago, during the Founding Festival, Hiccup and the rest of the Seven Deadly Sins were making their way down the dark corridors of the old castle. All of them were wearing armour, but only Hiccup and Heather were the only ones without their helmets.
"It's a shame that were missing the Founding Festival of the kingdom," Hiccup sighed. He was wearing armour that resembled that of the Night Fury.
"It would certainly be an excellent way to spend the time," Astrid agreed. Astrid's armour was a deep shade of blue, but it was relatively large to the others and resembled that of a Deadly Nadder.
"I'm sure we'll be able to catch the end of it," Hiccup assured.
"It sound as if the Inquisitor has something important to discuss," said Ragnar. Ragnar's armour was a very elegant looking suit of armour that resembled a Boneknapper.
"Maybe he's going to give us a special reward for our excellent handling business with the Troll Queen," Heather suggested wearing armour that resembled a Razorwhip.
Hiccup frowned. "I would hardly call it excellent and he's never done anything like that before."
Snotlout snorted in his armour that resembled a Monstrous Nightmare. "You're nothing more than a killjoy."
Hiccup and Eret, who was wearing armour that resembled a Rumblehorn then opened the doors to the audience chamber.
"You are to see us," Hiccup called.
However when they entered they found Inquisitor Zaratras dead and pinned to the wall by swords and spears. The entire room was filled with gashes and holes, indicating that there was a struggle.
"Inquisitor!" Hiccup gasped.
"That is brutal," said Snotlout.
"He's a pincushion," said Heather horrified.
"Who would do this?" Fishlegs stared. Fishlegs was wearing armour that resembled that of a Gronckle.
"More importantly why did they target the leader of the Dragon Knights?" Ragnar wondered curiously.
"You're right, the Inquisitor is the linchpin of the kingdom's defence," Eret nodded. "He is practically a war god, whoever killed him is a trader who must be plotting to overthrow Berk."
"And they knew precisely what his loss was going to mean," Heather added.
Fishlegs then turned towards the door. "I sense something."
Hiccup immediately rushed towards the nearest window and there standing at the base of the old castle were dozens if not hundreds of Dragon Knights.
"We're completely surrounded by every Knight in the kingdom," he said.
"There are too many of them out there to count," said Heather bending down to look at the window. "What are they planning to—"
Suddenly the entire castle shock violently.
"Damn, they've started their attack," said Snotlout.
Ragnar looked at Hiccup. "They clearly believe that we are the ones responsible, we've been framed."
Hiccup then turned and looked at all them. "We'll figure out what happened later, but for now we need to split up. I will gather you all once the time is right."
"Understood," said Astrid.
Immediately all seven of them went their separate ways.
Back in the present, Hiccup was still standing with Gilthunder's sword near his neck.
"We try diverging their forces in order to limit the casualties, but even still we have to fight our way out," said Hiccup. "After that I went to a nearby cave where I found Toothless."
"I knew it," said Ruby. "You really weren't the ones that killed the Inquisitor, where you?"
"That makes no difference to me," said Gilthunder.
Ruby stared at him. "What are you saying?"
"Rebels and traitors plotted to overthrow the kingdom, that's all you people are."
Twins stared at one another than back at Gilthunder.
"Did you hear a single word he said?" Tuffnut stared.
"Yeah, he just said that they were responsible!" Ruffnut yelled.
Ruby nodded. "They weren't the ones that murdered him, don't you understand?"
Gilthunder looked at Ruby. "Ruby… the kingdom wants you into protective custody. But I haven't the slightest interest in that." He then withdrew his sword from Hiccup and then pointed it at Ruby. "Alive or dead it's the all the same, to me you're nothing more than a grain of sand on the road that's been travelled."
Suddenly the bounds holding Ruby immediately dispelled freeing her.
"Go away, the Sins and I have some unfinished business," he said.
Ruby however placed herself between Gilthunder and Hiccup and Heather.
"I won't let you hurt these people!" she yelled.
Gilthunder looked at her for a few seconds and then turned the twins. He then immediately kicked them hard a powerful spinning kick knocking them to the ground.
"Ruff! Tuff!" Ruby cried rushing over towards them.
Gilthunder then turned and faced Hiccup and Heather. "Now that we have dispensed with that interruption."
"Are you sure about this?" Hiccup asked as he approached him. "In the old days you were never able to beat me."
"But that was a long time ago," said Gilthunder looking at him directly in the eyes. "I am now more powerful than any of the Seven Deadly Sins."
Hiccup looked at him emotionlessly. "Maybe you're right, but you can also be wrong."
"Then we should find out," said Gilthunder. "First I will release your bonds."
"I appreciate the offer, but I've got it," said Hiccup.
Then suddenly both Hiccup and Heather immediately dispelled the bonds that were holding. It became evidently clear that they were never actually bounded and only pretended.
"We could have escaped any time we wanted," said Hiccup looking directly at Gilthunder.
"Just know if I felt like it, I could annihilate you instantly," said Gilthunder.
"I very much doubt that."
"I shall use my sword to kill you."
"And I can easily do the same." Hiccup then turned and looked at Heather. "Don't interfere Heather."
Heather sighed. "You get all the fun."
"You certainly live up to your sin," said Gilthunder as he raised his sword.
Hiccup then suddenly stepped right in front of him. "Is it arrogance or simply confidence?"
They looked at one another for a few seconds and then they made their move. Lightning began to rain down from the sky and struck Gilthunder's sword as he slammed it down towards Hiccup. However Hiccup had merely blocked it with his own blade which was consumed by flames and then spun around with his flame covered blade and he vanished instantly.
"Looks more like confidence to me," said Hiccup.
"To me it's more arrogance," said a voice behind him. Gilthunder had somehow appear directly behind Hiccup and was ready to strike him with his blade. "Because you're about to die!"
However, Hiccup moved quickly managed to block the attack with his blade and then spun around to face him.
"Come on," said Gilthunder as he swung his sword at Hiccup, who immediately dodged once again.
Suddenly the two of them began to speed away through the forest with Hiccup on the defensive and Gilthunder chasing after him with his lightning covered sword. Lightning kept on heading straight towards Hiccup, who kept on blocking it with his blade.
Eventually he landed on a large boulder and Gilthunder stood there. "I have to admit, you have improved over the years."
"Yet you still believe that you're superior to me," Gilthunder noted.
Gilthunder then jumped into the air and swung his blade, but Hiccup quickly blocked the attack with his own.
"I can sense it," said Gilthunder looking directly into Hiccup's eyes. "You're beginning to feel a little fear creeping in."
Hiccup merely smiled. "Am I?"
Suddenly the blouder they were standing on crumbled and then they immediately launch themselves high into the air. They floated for that a few seconds looking at one another and then simply they vanished clashing with one another every single second they fell back towards the ground.
Gilthunder eventually managed to put so much weight against his attack that Hiccup was forced to move backwards and landed on the ground.
"You're certainly persistent," Hiccup noted.
Gilthunder then appeared directly in front of him and swung his lightning covered blade. Hiccup was hit so hard that he crashed into the boulder, but he emerged out of the dust. However, the moment he did a bolt of lightning headed straight towards him and he swung his flame covered blade to deflect it.
However, Gilthunder then appeared next to him with his guard down, he had no time to react as he was sent flying into the air by a lightning covered blade. Once floating in midair, Hiccup saw Gilthunder heading straight towards him with his lightning covered blade held high.
"Too slow!" he yelled.
Hiccup was immediately struck and crashed into the ground, but he merely laughed and picked himself up.
"I can't believe you've gotten this powerful," he said.
"Don't worry," said Gilthunder standing behind him holding his sword in both hands. "I will bring the others down with you soon enough."
He then struck Hiccup on his left shoulder with his lightning covered blade and Hiccup fell to the ground with blood pouring out of the deep wound.
Heather just stood there staring. "Captain?"
Gilthunder then turned him around with his foot. "Hiccup, the Seven Deadly Sins Sin of Pride. Do you have any last words?"
Hiccup looked at him, looking immensely weak. "The Sins… what happened to them? You must have heard something, right? Where have the other one's gone?"
Gilthunder then sheathed his sword. "Very well, I will tell you. For the remaining five, three of them are still at large and are not yet accounted for. But… the other two have been dealt with. The Fox Sin of Greed, is being kept under tight security at Grimbread Prison. The Grisly Sin of Sloth has already been slain and is interred in the Necropolis. But you needn't worry, I'll make certain that they will all join you shortly."
"Thank you," said Hiccup as he closed his eyes. Seconds later they immediately shot open. "But I think I can do that myself!"
He then immediately jumped onto his feet as if the wound on his shoulder didn't bother him in the slightest.
"But I appreciate the information," he said smiling at him.
