Thousand years ago, back when dragons dominated the land Acnologia was just a normal human back then he hadn't given himself the name Acnologia. As hard as it was to believe he was, in fact, a doctor and he lived in a mountain village which bordered between the West and East part of the continent.

He was currently healing an old Bewildebeast dragon with his magic.

"Ah, the pain is starting to fade," said the dragon. "As always I sincerely thank you for patching me up, doctor. It warms my heart to know that there are humans among us that have your level of kindness and understanding."

"Of course," said the young doctor. "But I'm afraid you give me too much credit than I deserve. I can stop the bleeding, but not heal you. The protection of your dragons give us is invaluable, although some would disagree. And I think of you as nothing less than our divine guardian, Acnologia."

Acnologia just looked down at the village where humans and dragons were living in harmony. However he knew it wouldn't last, there was a war going on between the East and West factions and both had different ideologies, but what was more troubling was a certain rumour he had heard.

"Doctor, I've heard an unsettling rumour during my recent travels," he said gravely. "There's talk of a new type of magic to the West of the continent with the sole purpose of killing dragons. Our future will be filled with needless fighting unimaginable slaughter. I can feel it in my scales."

The doctor just stared at him. "Mortals taking arms against dragons? Who has such hubris? It would be impossible."

"Foolish at the very least, however, this dragon killing magic has the potential for great harm."

"If such terrifying sorcery exists, I couldn't protect you I'm simply not strong enough for that. I barely have enough magic power to tend to you now, if only I was stronger."

"What matters most is heart not strength, never lose sight of that fact," said Acnologia as he stretched his wings. "Doctor I intend to travel west to see for myself if there is any truth to this dragon killing magic. If it's real… it poses threats to land such as ours were dragons and mortals coexist peacefully. We could be caught along and bloodied conflict."

The young doctor then watched as Acnologia took off heading west.

"Go with care, Acnologia. I will be praying for your safe return," he said. "Mortals committing violence against the dragons. This Dragon Slaying Magic… it sounds like a fantasy, but if it is true it leaves me with an overwhelming feeling one of dread. I'm not strong enough to fight it."

A few weeks later, dragons then started to attack the village killing everyone in it. Acnologia had been badly injured, but he was very much alive and was running clutching his arm. Then he saw Acnologia, badly injured and leading the attack.

"Acnologia did return to our hidden land and he brought death and destruction with him."


Back in the present, Acnologia was now facing every single Dragon Slayer still alive within the Time Rift, but he wasn't concerned in the slightest.

"Let's do this!" Hiccup yelled and led the charge.

"Yeah!" they yelled as they followed him.

"You can hear me, right Cobra?" Alvin asked.

"Now there's a stupid question," Cydor smiled.

"Old physical abilities will now be enhanced with my Deus Eques!" Merrill yelled as she cast her spell.

Everyone then suddenly found their strength and speed increased as a powerful aura covered them.

"Oh yeah, this is awesome!" said Sting.

"This power is incredible," said Rogue.

"She may be small, but she's got some powerful tricks up her sleeve," said Eret.

"Don't let up, hit him with everything we have!" said Valka.

Eret's hand then transformed into a sword. "Iron Dragon's Sword!"

He extended the blade towards Acnologia striking his chest, but it merely bounced off him. Sting and Rogue then came in close, but Acnologia merely waved his hand creating a massive amount of wind pressure that sent them flying.

Alvin, Valka and Cydor then jumped into the air and began to attack in while his guard was down.

"Poison Dragon's…"

"Lightning Dragon's…"

"Sky Dragon's…"

Hiccup then began adding his own power into the mix. "Fire Dragon's…"

Acnologia merely flexed his palm striking Alvin, Valka and Cydor with a powerful surge of wind knocking them back and they flew right past Hiccup.

"Come on you guys, stay with me!" Hiccup yelled.

Cydor just stared at Acnologia. 'This guy's mind, total silence. I can't hear it.'

Acnologia then raised his finger began channelling an insane amount of power into it and pointed it directly at Hiccup.

"Get out the way Hiccup!" Merrill yelled.

Hiccup braced himself as the attack shot straight towards him at incredible speed. A few moments later there was a massive explosion, but when the smoke cleared Hiccup was still standing. However that little show did put everyone on edge, just demonstrated how much power Acnologia added his fingertips, literally.

"That sucked," said Eret.

"Crazy," said Alvin.

"We knew this wouldn't be easy," said Rogue.

"Thought we would get in a few hits at least," said Sting.

"He's barely even moved since we started," said Cydor.

"He's not to be taken lightly," said Valka

"He's powerful, but don't give up," said Merrill.

"I said that I will show you why they call me the Dragon King. Is the lesson beginning to sink in yet or will I have to start killing you?" said Acnologia.


In the physical world, everyone was rather concerned about Acnologia's body running amok trying to think of ways to take him down.

"There's no sugarcoating it, with all the Dragon Slayers stuck inside a Time Rift we are left with no clear path to victory against Acnologia," said Gobber.

"Seems like it," Ragnar agreed.

"We're in trouble," said Toothless.

"What now?" Heather asked.

"We've got no choice but to fight," said Astrid.

Everyone was silent, not even the most powerful members of Dragon Tail were able to defeat Acnologia and they have five Dragon Slayers at the time.

"Maybe we can't kill it, but you think we can mobilise it or something?" Ragnar asked.

"That's a good idea, you could freeze it in its tracks with your ice magic," Heather suggested.

Astrid shook her head. "Not an option, Magic has no effect on him."

"We've got all these Vikings gathered here and you're telling us that magic is not going to work?" said Orga.

"Is there a sword or some other kind of weapon we can use against him?" Skullcrusher asked.

"If it was that easy to kill a dragon, somebody would have done it already," said Salazar.

"That only happened in children stories," said Yeren.

"But we shouldn't rule that out entirely," said Maarva.

Astrid shook ahead. "No, a sword would only be effective in view Dragon Slayer Magic."

"If only Merrill was with us," said Stormfly.

Toothless eyes lit up. "What about Inferno?"

"Dammit, we've got nothing," Garon cursed.

Snotlout looked at him. "Hiccup's sword? What about it?"

"Well, he's been channelling his magic for it for a long time and it's made of a special alloy that absorbed magic," said Toothless. "Maybe absorbed his Dragon Slayer Magic."

Everyone's eyes lit up.

"That could work, but wouldn't it be inside the Time Rift with him?" said Astrid.

"Hiccup said that he left his sword at the Guildhall after his fight with Drago so it should still be there," said Ragnar.

"I hate to point out the obvious, but Acnologia isn't going to go down just because we have a special sword," Gobber pointed out. "We're going to need more gonna take that monster down."

Fishlegs noticed that Ruby was thinking hard. "You've got something? What is it?"

Ruby smiled slyly. "Actually, there may be one thing we can do."

Everyone looked at her wondering what she came up with, but then suddenly there was a huge explosion just outside the city.

"Here he comes!" Gustav yelled.

Acnologia was flying directly towards them and explosions erupting around him.

"He's just mindlessly destroying everything he sees," said Gildarts.

"We've got a get out of here right now," said Garon.

"Ruby if you've got a plan, spill it," said Agatha.

"We have to use Inferno to immobilise him," said Ruby.

"Yeah, but it won't last long and then you go on a rampage again," said Shiva.

"It will give us our only chance… to use one of our strongest spells!" Ruby yelled.

"Magic won't work on him remember?" Orga reminded her.

"I heard that, but I think there's one spell that could," said Ruby and then turned to Fishlegs and Fenris. "Fishlegs and Fenris, I'm going need both of you to come with me. We'll be searching for the Guild's library for the spell!" She then looked at Toothless and the Exceeds. "You guys will help us catch up when we find it. The rest of you need to figure a way to lead Acnologia away. Whatever the case it's important that we have as many Dragon Tail members gathered up in one place as possible."

"Well if that's the case Sabretooth will take point in luring the dragon," said Minerva.

"What makes you think this spell will work? Why is it special?" Vala asked.

"It's matter created by close personal bonds, that even Acnologia can't break."

Astrid and the rest of Dragon Tail then realised what she was planning, there was only one spell that Acnologia had failed to overcome. It was the same spell that kept them in suspended animation for seven years and briefly caused Cove Island to be wiped off the map. One of the three grand Dragon spells… Dragon Shield.

"It's his spell," said Agatha.

"It saved us on Cove Island way back then," said Skullcrusher.

"That's true, absolute protection magic," Gildarts nodded.

"One of Dragon Tail's three grand Dragon spells… Dragon Shield," said Ruby.

"It's true that he didn't overcome it, but that spell was only meant to be cast defensively," Fenris reminded her.

Astrid looked at Ruby bewildered. "Are you saying?"

"You're really suggesting that we try to trap Acnologia?" Stormfly stared.

"Inside the Dragon Shield?" said the other exceeds.

"That plan is insane Ruby," said Garon.

"It's all we have," said Ruby bluntly. "This is our last shot, it's all or nothing."


Inside a Time Rift, Hiccup and the rest of the Dragon Slayers were still battling against Acnologia and it was clear they were struggling. The Chronicler just stood there watching the confrontation, she hadn't even budged an inch.

"As we stand inside here, my flesh form is on a path of rampant destruction outside the Time Rift bringing about the end of the world," said Acnologia. "The hour of reckoning is now upon us, civilisation has reached its demise."

"Why are you doing all this?" Hiccup asked.

Acnologia smiled evenly. "It's simple… to bring destruction."

Everyone just stared at him as he laughed, they just couldn't believe that all he wanted to do was destroy everything.

Hiccup then rose to his feet. "And you call yourself a king? My father taught me that whether you're a king, a Guild Master or in any position of authority that your duty is to protect your own. The world is not yours to destroy and we will stop you no matter what!"


At the Shivering Shores, Thor's Hammer and Valkyrie Sword was still sitting on standby at the port unaware of what was going on. Then suddenly appearing completely out of nowhere was Garon with Ragnar and Heather in tow.

"Ragnar and Heather are here?" Lyon stared and looked at Garon. "And… uh…"

"My name is Garon," said Garon.

"Wouldn't it have been better to take all of us at once?" Ragnar asked.

"Wouldn't be better for me," said Garon.

"He can only take a couple of people at a time," said Heather.

"What's going on?" Lyon asked. "I had heard that the fighting is over."

"Not yet," said Ragnar. "Acnologia is on his way here."

"We have a plan in motion, but we needed to get away from Berk," Heather explained. "The rest of our Guild should be here momentarily, but we need as many people to keep Acnologia at bay as long as possible until we're ready."


Astrid was leading the rest of the Guild towards the Shivering Shores, apart from those who were able to fly everyone was writing in wagons.

"Shivering Shores here we come!"

"Lots keeping the Garon Express?"

"Give him a break, man!"

"Good luck friends," said Astrid. "We're counting on you."


Acnologia was at this very moment flying directly over Berk.

"So that's him," said Maarva.

"The arcane Dragon himself," said Yeren.

"I'm not quite sure how we're going to lead him all the way to the Shivering Shores," said Minerva.

"His magic power is crazy," said Orga.

"I can't recall beast this strong," said Illos.

"But we are strong too," said Vala.

"You better believe we are!" said Hookfang.

"Let's show him what we are capable of," said Skull.


At the Guildhall, Cloudjumper had found Inferno and looked up at Ruby and the others.

"I'll get this to Astrid," he said as he summoned his wings. "Good luck trying to find the spell."

"Stay safe," said Ruby as they watched him fly off.

They didn't waste a moment and began looking through the library, looking through every book they could get their hands on.

"Damn it can't find it!" Fishlegs yelled.

"No luck here either," said Fenris.

"Even positive that this book even exists?" Skullcrusher asked.

"I'm sure the First Master would have written it down," said Ruby.

"This is the only place it could be, we're just not looking hard enough," said Toothless.

"You're right," Stormfly agreed.

"We have to find it," said Ruby frantically. "The Dragon Shield is the only hope we've got left."


Outside everyone was doing what they could to keep Acnologia at bay, but all the spells they fired he just merely absorbed.

"No!" said Minerva looking utterly terrified. "Nothing we've done has had any effect."

"He consumes everything, all magic types!" said Illos.

"And he's not filling up," Yeren added.

"If he doesn't have a magic preference how do we get in to follow us?" Salazar asked.

Acnologia then fired down on some houses close to them, setting them on fire almost immediately.

"I can't really tell what he's aiming for," said Shiva.

"His attacking randomly, almost as if he has no mind of his own," said Maarva.

Acnologia then fired at the Guildhall much to their horror.

"He just try the Dragon Tail Guildhall!" Hookfang yelled.

"Oh no!" Skull panicked.

When the smoke cleared they were all relieved to find that Acnologia had only attacked the right side of it. The Guildhall was still standing and his attack only cause some minor damage, but the attack had enough force to cause the entire building to shake.

This meant that in the library all the books fell down on top of Ruby and the others.

"Good thing the library is underground, we should be safe down here," said Fishlegs.

Outside everyone was not holding out much hopes with guiding Acnologia to the Shivering Shores.

"This is bad, we must put a stop to the tax before he completely destroys Berk," said Minerva.

Orga smiled. "I've got this milady." He then fired his dark lightning directly towards Acnologia. "Hey, Acnologia!" The attack struck Acnologia right on the face and Orga then immediately began running off to guide him away. "I'm right here! Come and get me!" He then stopped when he saw that Acnologia hadn't moved an inch. "Can't you hear me?"

His attack did not affect Acnologia, it was almost as if the attack had been nothing more to fly to him.

"What the? Magic attacks and taunts don't work?" Orga yelled.

"If Acnologia has not even control over his own thoughts why did he come to Berk?" Vala asked.

"I was pondering the same thing," said Illos. "What could be driving his actions now?"

"It's pure instinct, he was drawn to this town because he sensed the magic power the Vikings here," Minerva concluded.

"Then perhaps the stronger the magic the more he'll follow?" Maarva theorised.


Back in a Time Rift, Hiccup and the other Dragon Slayers was still doing battle against Acnologia in the putting everything they had into their attacks.

Sting and Rogue had jumped into the air clenching fists of light and shadow and swung towards him. However, Acnologia merely raised his left leg and used it to block their attacks and then pushed them back sending them crashing to the ground.

"Sting!" Hiccup yelled as he ran past him.

"Hiccup!" Sting yelled.

Hiccup then launched himself and then swung a blazing right fist at Acnologia, but he leaned back and dodged it. Hiccup then spun around and try to strike him with a spin kick and then came back around with another front jab, but Acnologia avoided them all and then punched him hard in the stomach so hard in fact that he spat out some blood.

"Hiccup!" Cydor yelled with a fist covered in poison.

Eret and Merrill then joined him in a three-point attack, but Acnologia blocked all of their attacks. He stopped Cydor's poisoned covered fist with his palm, Eret's iron sword with his elbow and used his right knee to block Merrill's fist of water. He then unleashed a powerful explosion sending the free of them backwards.

Valka then quickly charged in and swung a powerful kick covered in wind and at the same time Alvin charged with his entire body covered in lightning and then punched him. The two attacks made contact and there was a huge explosion hiding them all from view.

"Nice going," Hiccup winced.

"Not too shabby I say," said Cydor.

"Valka and Alvin are incredible," said Merrill as she healed Eret.

"Yeah, that's what I'm talking about," said Eret.

"Did they get him or what?" Sting asked.

"The smoke is clearing," said Rogue.

However, when the smoke cleared they saw that both Valka and Alvin were on the ground. Acnologia didn't look phased in the slightest and he had a foot on top of Alvin's back in triumph.

"You bastard," Alvin snarled.

"We won't give in," said Valka.

"Your magic has no effect on me," said Acnologia.


Back in the real world, Ragnar and the others had just finished explaining to Lyon and the others on what was happening. They also explained their plan and Lyon looked rather dubious.

"You really think that Hiccup's sword can immobilise Acnologia?" Lyon asked sceptically.

"It's a shot in the dark, but we don't have an awful lot of options," said Ragnar.

"Even if there is a 1% chance that it works I say that we take it," said Heather.

"You can leave the sword to me," said Astrid as she and the others arrived.

Heather looked at them relieved. "Thank goodness, I'm glad that you made it here safely."

"We've done some crazy things before, but this takes the cake," said Ragnar.

"Even if we aren't able to take him down with magic, I bet we can push him around a bit," said Gildarts.

"I think I can do it… no, I'll do it no matter what," Astrid promised.

"But this plan does rely upon other factors," Heather pointed out.

Garon nodded. "Minerva and her team have to figure out how to lead Acnologia all the way here."

"Plus Ruby and the others have to make it in time," Agatha added.

"Plus we still need the sword," said Ragnar.

"That shouldn't be a problem," said Couldjumper's voice. They looked up and saw him flying down towards them holding Inferno, he then flew over to Astrid and handed her the blade. "Special delivery, one dragon-slaying sword."

Astrid took the blade. "Now it all comes down to Ruby and Minerva's groups."


Ruby and the others were rather shaken from Acnologia's previous attack and it had not several bookshelves down.

"Is everyone okay?" Fenris called out.

"It's a miracle, but yes," said Skullcrusher.

"I'm okay, but I'm a little stuck," said Toothless as his lower torso was buried in books.

"You not badly injured are you?" Stormfly asked as she pulled Fishlegs out of the books.

"I'm fine," he assured her and then looked around for Ruby. "Hold on, has anyone seen Ruby?"

Ruby's hand then popped out from the books holding an old book which bore the Dragon Tail emblem. Everyone's eyes widened because it seemed as if they had found the book they needed.

"You guys, I found the book!" Ruby smiled excitedly. "This will tell us how to use Dragon Shield."


In the spirit world, Hiccup and the Dragon Slayers were getting overpowered by Acnologia, who had just blocked an attack from Cydor and then kicked him in the chest knocking the wind right out of him.

'Oh crap,' he groaned as he fell. 'That one got me.'

"Hang in there," Hiccup groaned as he fell next to him.

"Don't worry," said Cydor as he picked himself up. "I can't let myself kick the bucket quite yet. Not just for my sake, it's because I've got friends of my own too and I know that they are fighting their heart out there! I'll do whatever the hell I've got to do to keep them safe!"

"We have to take this joke down or we'll never be able to show our faces again," said Sting as he stood up.

"This is the only way we can get back home, we have to win this fight," said Rogue.

"We won't let you kill my son or anyone else, you got that?" Alvin vowed.

"So we're going to have to go ahead and crush you before you get the chance to crush us," said Eret.

"You may be some kind of legend, but your story ends today!" Merrill yelled.

"There are too many people depending on us and we won't fail them!" said Valka.


Minerva and her group were starting to lead Acnologia away, it was a sort of like a relay race. A couple of people would unleash their magic and run towards the next group in the process would carry on until they made to the Shivering Shores.

"Acnologia, follow me!" Maarva yelled.

"Maarva, radiate all of your magic power you can," said Yeren.

The two of them then unleashed their magic power, though Yeren had unleashed the magic coming from his gauntlets rather than through his body. Acnologia immediately reacted when he saw this and started flying towards them.

"We can definitely blow him this way," said Maarva.

"It does seem to be working," said Yeren.

Salazar was racing along with Shiva riding on his back. "Hurry, Shiva we should be at the next point coming up soon."

"Full speed ahead, Salazar!" she yelled pointing onwards.

They soon reached the next group which was Orga and Illos and they were running down the canyon with Acnologia hot on the heels.

"Hey, ugly try and keep up!" Orga taunted.

"The fact that you're drawn to magic power is burned into my memory," said Illos.

Then when Acnologia was just about on top of them Minerva and Vala flew in being carried by Skull and Hookfang.

"We'll act as bait from here," said Minerva.

"Okay, Hookfang, don't stop until we reach the Shivering Shores," Vala instructed.

"You got it," said Hookfang.

"That won't be a problem," said Skull.

At Berk, Ruby and her group were now flying towards the Shivering Shores as fast as they possibly could. Toothless was carrying Ruby while Skullcrusher had Fishlegs and Stormfly held onto Fenris.

"Fly as fast as you can," said Ruby.

"You got it," said Toothless.

"Can you read it Fishlegs?" Fenris asked.

"I think I can translate," he said.

"You've got this, Fishlegs," said Skullcrusher.

"We believe in you!" said Stormfly.


Hiccup and the Dragon Slayers were now all standing tall as they prepared for the final clash between them and Acnologia.

"Are you ready for the final battle?" Hiccup asked. "Because we're only just getting started."

"Final?" said Acnologia. "We haven't even begun to fight, but this will be your end."

Acnologia then laughed.


In the real world, everyone could see Acnologia approaching them.

"Here he comes!" Gildarts yelled.

"This is our shot," said Astrid as she held Inferno.

"We need a buy some more time and to Ruby and the rest of them get here," said Garon.

Gildarts looked at the members of Dragon Tail. "You guys get ready for the Dragon Shield, you hear me!"

"What you mean by that?" Gustav frowned. "How do we get ready for it?"

Snotlout then grasp hold of Rubbella's hand and then slowly everyone began holding hands.

"Everyone we must hold hands," Agatha instructed.

Astrid looked up at Minerva and Vala. "Good work, ladies. I knew we could count on you."

"He'll follow whoever put out the strongest magic power," said Minerva.

"If you do that you can catch by surprise," said Vala.

"As for us…" said Minerva weakly.

"I'm sorry but I think we're running way too low," said Vala as Hookfang and Skull had trouble keeping them airborne.

"For sure," said Hookfang.

"Can't stay airborne for much longer," said Skull.

"We can take over from here," said Astrid then she raised Inferno. "Everyone the final battle is now! Give it everything you have for our fallen friends for all of us!"

Everyone then cheered as they got ready for the battle of their lives.
