At Berk everyone is waiting patiently for the arrival of Duel Academy and suddenly they saw the skies were opening up.

Eisenstein was in his command centre when it happened. He looked at the readings and saw the porthole was becoming even wider.

"Look! The portal is opening!" he yelled.

Then suddenly without warning a beam of light launched from the skies above and right into the crater where Duel Academy once stood. It was so fierce that the interdimensional duel system was completely destroyed everyone in the vicinity was completely blinded by the light.

When the light faded they saw that Duel Academy had arrived in one piece.

"It returned," said Eret.

The moment they had returned back to Berk everyone had become a Duel Ghoul had returned back to normal and were slowly waking up with a massive headache.

"What happened?" Snotlout groaned clutching his head. "Where are we?"

"I hope some with friendly," said Fishlegs as he got his feet steadily. Then he noticed something on his wrist. "My Bio Band it's crumbling away."

Seconds later his Bio Band turned to dust in the same thing was happening to everyone else's band.

"Whoa," said Astrid.

"Looks like were finally free of them," said Ragnar looking at his bare wrist.

"What a relief," said Heather.

"What the—?" said Wartihog as he woke up.

"Are we okay?" Thuggory asked.

"Yeah," said Blaze as she looked up. "And from the looks of it back home!"

"She's right! I mean just check it out! Blue skies, birds chirping, the ocean splashing!" Wartihog cried.

"And best yet…" said a Ra excitedly.

"No Duel Ghouls," a Slifer finished.

Everyone began to cheer.

"At last we are finally back safe," said Phlegma.

"Yes, my Mason, my students," said Mildew.

"And most importantly me," said Spitelout.

"I see the journey to another dimension hasn't changed you," Gobber grumbled.

Gothi then made her way over to Hiccup and Mason who were still out cold. She checked Mason first and seconds later Hiccup opened his eyes.

"Did we make it back?" he asked.

He then saw that Mason was out cold and looked up at Gothi.

"He'll be fine," she assured. "And to answer your question Hiccup: yes thanks to you were home."

Blaze was peering up as she looked at Mason. "Hear that Mason we're home."

"I can't believe we actually did it," said Hiccup getting to his feet. "Can you Camicazi?" However she didn't answer and Hiccup looked wildly for her. "Camicazi?"

He then remembered that Camicazi remained behind to keep the portal open and he also remembered Phantom. Immediately guilt flowed into him in an uncontrollable flood.

"Oh no, the duel," he stared shaking uncontrollably. "She said she was giving it her all. Oh no, Camicazi!"


A few hours later there was a massive party at the Obelisk Blue dorm celebrating the safe arrival of all the students from that weird dimension.

"So you had little food, monsters attacking you everywhere you turned and top it all off the students turned into zombies," said Stoick looking at Gobber.

"Things did get a bit hectic," Gobber nodded. "Anyway we've done a headcount of only two students missing. Camicazi and Agnar Geckoson."

"From all reports Camicazi remained behind a whole the portal as for Agnar he just disappeared without a trace," said Mala. "Still it could have been a whole lot worse considering the circumstances."

"Indeed, Hiccup and his friends are certainly heroes for bringing this many students back," said Pegasus. "Still there are questions that remain unanswered."

"Like?" Gobber asked.

"Like how this world exists," said Pegasus with a dreamy look. "Oh, how I would I very much like to study it."

"Study?" said Stoick narrowing his eyes. "Pegasus there are still people missing!"

Pegasus nodded. "Of course, how insensitive of me."

"Agnar and Camicazi are still out there and they happen to be children some of the most powerful families in the world," Stoick reminded. "Our only hope is that Professor Eisenstein determines the reason behind this incident so that it never happens again."


Eisenstein was in his mobile lab with Speedfist as they were going over the readings.

"And Camicazi and the Celestial King card?" Eisenstein asked.

"That's right, neither have returned yet," said Speedfist grimly.

"Then they're trapped, the odds of finding another signal are…"

Suddenly they heard a beeping sound and then turned to the monitor.

"You were saying?" said Speedfist.

"I can't believe it," Eisenstein stared. "It's a—" He then looked at Speedfist. "Well I'm not sure what it is, but it's definitely something."

"Indeed, but what?"


At the Ra Dorm, Mildew was looking over Mason who was fast asleep in his bed.

"I'm so sorry Mason," he said sitting down next to the bed. "I wasn't there when your parents die and I didn't look after you like a guardian should have. That spirit took you because I was never there for you. Whether it was denying that you were my son or travelling to pursue my duelling career I thought I was doing it all for you, but now I realise how wrong I was."

"Grampa?" said Mason's voice.

Mildew looked up and was relieved to see that Mason was wide-awake. "It's all okay," he said. "You're here now that is what matters. And if it took that spirit are taking over me for us to get closer then it was well worth it. I love you grampa. Let's just be a family again only without the whole me being possessed thing."

"I would love," said Mildew.

Blaze had been listening in at a crack in the door and tears were running down her cheek. "Welcome home Mason."


Meanwhile Astrid and the others were at the Slifer Dorm concerned about Hiccup along with Astrid's older brother Agnar. Neither of them had seen much of it since they got back and those of hit them that had barely got a word.

The door open and Snotlout looked up expecting to see Hiccup

"Hiccup?" he said and then he noticed entering into the room were Fishlegs and Warthiog. "Oh, it's just you losers."

"What?" Wartihog roared. "You've got some lip!"

Fishlegs looked at the others. "So you haven't seen either?"

"Afraid not, Legs," said Thuggory. "He must still be in that funk. Blaming himself for Camicazi.

"Yeah, but I wonder if there's more to it," said Axel with his arms folded and eyes closed. "Something about that spirit that took over Mason. Hiccup seems to have some kind of link to it. What is that spirit true target was actually Hiccup the whole time?"

Everyone gasped.

"Come on, where are you getting this stuff?" Snotlout asked.

"The duel. I overheard a couple of things, not enough repeated altogether though."

Heather looked at Ragnar. "Do you know what's going on? I mean you've known him longer than any of us."

"He's never mentioned that this spirit before," Ragnar shrugged. "Though all the kids in the neighbourhood seem to be afraid of him."

Heather stared at him. "Hiccup scaring people? He wouldn't hurt a fly."

"That's the impression I got, because everyone kept their distance from him and kept on telling me not to get involved with him," said Ragnar.

Astrid frowned. "I wonder if…"

"If what Astrid?" Agnar asked. "If you know something spill it."

Astrid looked at them all. "After we got back everybody was in a great mood, everybody except Hiccup."


Astrid was looking at the one sun in the sky and felt immensely relieved that they were finally back home. However, she then noticed that Hiccup was looking extremely depressed as he leaned against the wall curled up into a ball.

"Hiccup?" Astrid frowned.

"It's me," he said muttering to himself quietly. "It's my fault. Everything was because of me. It's all my fault."

Astrid then quickly ran over to him and grasped his hands. "Listen! Don't say that! Everyone was rescued thanks to you Hiccup! It's not your fault. How could it be?"

"Because I know the spirit that possessed Mason," he said.

Astrid gasped and was completely taken aback.

"Her name… is Phantom."


Back in the present, Astrid finished the story on everyone was listening with great interest.

"Phantom. After that he wouldn't say another thing," said Astrid.

Suddenly the door opened again and everyone gasped as Stoick entered.

"Chancellor Stoick?" Snotlout gasped.

"It would seem as if you all deserve to know the truth," he said closed the door behind him. "And judging from what I overheard Astrid said I came in a good time. It was roughly 10 years ago, back then me, Alvin and Gobber were beginning the construction of Duel Academy and Valka, my wife, was busy designing cards for Pegasus at Industrial Illusions. The story begins when Valka finished designing the first series of the Dragon Knights, the very first card that she made Hiccup had a very deep connection to its spirit."

Everyone gasped.

"Let me guess spirit by the name of Phantom?" Astrid guessed.

"That's right," Stoick nodded. "But there's more to the story than just that. As you might have expected both me and Valka will rarely at home, because of long hours of work. So, Hiccup would invite various kids in the neighbourhood and spent all his free time duelling."


A seven-year-old Hiccup was sitting up with one of his neighbourhood friends called Sven and the two of them were having a duel.

Hiccup: 1800

Sven: 2200

"And then one day," Stoick continued.

"All right, here goes. I draw," said Hiccup as he drew from his deck and he saw that the card he had drawn was Phantom.

'Nice I can finally call you out Phantom,' he said with a smile.

"She was Hiccup's favourite card," said Stoick.

"Okay I sacrifice when Baby Dragon and Winged Dragon, Guardian of the Fortress to summon Dragon Knight Phantom," said Hiccup sacrificing his only two monsters on the field to summon Phantom.

"Then I'll activate the trap card Perfect Counter Code 123," said Sven revealing his facedown card. "With this card if there is a level 1, 2 and 3 monster on my field a special effect activates. One that negates Phantom summoning and then destroys her."

"Phantom," Hiccup groaned as he was forced to send Phantom to the graveyard.

"All righty, my turn," said Sven as he drew. "Dragon Zombie, Clowns Zombie and Skull Servant attack!"

Hiccup: 0

Sven: 2200 (Winner!)

Hiccup then toppled over his chair and landed hard on the floor.

"Hiccup are you okay?" Sven yelled rushing over to him.

'For shame Hiccup, for shame,' said Phantom's voice softly.

Hiccup then saw that Phantoms card landed in front of him and he picked her up. "Sorry, Phantom. I did my best to call you out."

"Don't get down on yourself," said Sven helping him up. "You played well, Hiccup."

"Well not well enough," said Hiccup. "I couldn't summon Phantom as usual."

Sven laughed. "You're always trying to summon her. Why not try a different monster? You know pick something with a lower level maybe?"

"You don't understand," said Hiccup looking at the Phantom card. "Mum created Phantom for me it really means a lot to me. It's almost like sometimes I actually her. Asking me to summon her."

"Come on, Hiccup. Now you're just talking crazy."

'Oh, is that so,' said Phantom.

Then suddenly without warning Sven collapsed.

"Sven! Says something! Somebody help!" Hiccup yelled.


Back in the present, Stoick just finished that tale.

"The doctors ran all sorts of tests, but they could find no explanation for his condition… medically speaking," said Stoick.

Everyone gasped.

Astrid looked up. "Wait, then…"

"You're saying that it was Phantom?" Agnar gasped.

"Nobody can know for sure, but I do know that each time Hiccup put Phantom in his deck things would always happen to his opponents," said Stoick. "Eventually everybody in the neighbourhood got spooked and refused to duel Hiccup so long as he had back card."

"So what did the Captain do?" Wartihog asked.

"Well, as luck would have it, KaibaCorp was accepting card submissions during the same time. The winning designs would be sent to another dimension and be infused with strange dimensional matter. Hiccup submitted the designs for the Dragon Spirits which were accepted, but he, with some help from Valka, managed to convince KaibaCorp to send Phantom.

"He looked back card so much he couldn't get rid of it. Instead, the dimensional energy infusion would make her safe to us. And so two satellites were sent to an alternate dimension. One with Phantom and the other with the Dragon Spirits. The multi-verse did their thing and made the Dragon Spirits a great success, but Phantom on the other hand… well, we are just learning the effects. Effects that are quite troubling and that only perhaps Hiccup has any true insight into."


Hanging outside was Eret, who had her the entire conversation. 'So then it wasn't just my Demon Knights card and Hiccup's Dragon Spirits that were touched by the multi-verse, but Phantom was too. Very, very interesting.'

He then heard footsteps and turned and found Wolflegs appearing behind the corner.

"That you Wolflegs?" Eret asked.

"Tell me, you wouldn't happen to have any interest in that Phantom card would you now, Eret?" Wolflegs asked suspiciously.

Eret merely shrugged. "Of course not. What you are about some AWOL duel spirit?"

Wolflegs smiled. "You tell me."

He then winced in pain and clutched his chest.

"You okay?" Eret asked standing up straight. "What's wrong?"

"Nothing," said Wolfelgs shaking the pain off. "I'm fine."

"All right, not like I anyway," said Eret.

'Phantom,' said Wolflegs to himself. 'The highest level spirit, she will make a fitting opponent for a duellist of my calibre.'


Hiccup was in his room in a state of mental depression.

"It's all my fault. Sending her to another dimension without a clue on what could happen," he said. He then slammed his fist on his pillow. "I should have gotten rid of her when the trouble first started, but now because of me Camicazi is gone."

"If it is anyone's fault it is mine," said Toothless as he appeared in front of him.

Hiccup looked at him. "You knew it was her, didn't you?"

Toothless sighed. "Yes."

"Why didn't you tell me?"

"Because I knew how you would react," said Toothless. "Your main priority was to get us back home, not feeling sorry for yourself."

"But it was my fault that all this happened!" Hiccup yelled in frustration.

"The other Knights and I didn't act until it was far too late. She always took her duty far too far we can convince her to stop."

Hiccup looked at him. "What are we going to do about Camicazi?"

Toothless looked at him. "There may be a way to get her back."

Hiccup looked up. "Tell me."


It was late at night and Astrid and the others were looking at one another.

"Do you believe that story Stoick just told?" Thuggory asked.

"Well, I wouldn't have done a week ago, but after everything we've gone through," said Astrid.

"It would certainly explain why the children in the neighbourhood were afraid of him when Mum and I moved in," said Ragnar.

"At least it's all over now, Phantom vanished in the other dimension right?" said Agnar looking at everyone. "So that means we don't have to worry about her anymore."

"Yeah, you're right," Fishlegs nodded.

"I have a feeling when I get off that easy," said Heather.

"We've got trouble!" Speedfist yelled as he entered the dining room. "A portal is trying to open again between our two dimensions. I don't know how, I don't know why?"

"So what?" said Snotlout getting to his feet. "Duel Academy is going to get swallowed up again."

Speedfist shook his head. "No. This is a much smaller portal, but if my calculations are correct it can open in an hour."

"What?" said Thuggory. "Opening in an hour? Where at?"

"And the graveyard ruins of the Royal Family," said Speedfist.

"I don't want to become a Duel Ghoul again," Fishlegs panicked.

"Guys, if Hiccup hears about this you'll know what you do," said Astrid.

Everyone gasped.

Immediately they rushed to Hiccup's room.

"Hiccup!" Ragnar yelled as he opened the door.

When they ended inside they saw that his bunk was empty.

"He's not here," Fishlegs gasped.

"So where did he go?" Wartihog asked.

"I think the answer is obvious," said Axel.

"But I didn't tell Hiccup where the portal was taking form," Speedfist reminded.

Then the Ojama's appeared next to Snotlout.

"Maybe it was Toothless, Boss," said Yellow. "He was quite concerned about something."

"Tell me," said Snotlout.

"I just knew it," said Astrid shaking her head. "He's trying to go back for Camicazi."

"Whoa, back to that scary place all by himself," said Agnar.

"Hiccup is blaming himself for Phantom's attack and Camicazi was a casualty in that war," Ragnar pointed out. "If there was even a chance that she was alive, he'd take it.

"He's right," Axel nodded. "This could be Hiccup's one chance to make it right."

"Well he's got it wrong if he things we're not backing them up," said Thuggory.


Hiccup had grabbed his backpack and was following Toothless deep into the forest to the ancient ruins.

'I'm coming Camicazi, don't you worry,' he said to himself. 'I've got you into this mess and I'm going to get you out.'


It wasn't just Hiccup and the others who aware of the portal re-materialising. Echo had managed to escape the clutches of the Order of Knights and was now on her submarine overlooking Berk she had heard everything from the island regarding the return of Duel Academy.

'I knew you wouldn't return from that alternate dimension with the others, Agnar,' she said to herself. 'I knew you would say just as I have that you are destined to become the ruler of that strange wondrous world. You will be its ruler, I'll make certain of it.'


Hiccup was still making his way through the forest unaware that Gobber was close by.

"What do we have here," he said emerging from the bushes. "It would seem as if young Hiccup is on a midnight stroll and judging from the bag he has on his back is going to be a very long stroll."

Hiccup finally reached the ruins and Toothless came to a stop.

"This is where the portal is located," he said.

Hiccup looked up at the dark clouds that was swirling around and Toothless vanished. He then noticed a small light a few feet away and knew instantly that it was the portal he quickly made his way towards it.


Not too far away were Eret and Wolflegs the two of them had seen the portal not too far way.

"What's that in the distance?" Eret asked.

"A door way to another dimension," said Wolflegs.

"Is that Hiccup heading for it?" said Eret looking surprised.

"The poor kid never learns," Wolflegs sighed. "He barely escapes the first time."

Eret's eyes widened when he realised what Hiccup was up to. "Camicazi! He must be going after her since it was his fault and all."

Wolflegs shook his head. "'His fault?' That's not it."

"What?"

"Oh, he may think that it his, but I know better. He's doing it because he's looking out for his friends, they all do."


Hiccup was now standing in front of the portal preparing to make the plunge.

"Camicazi," he said unaware of them approaching him. "Hang on."

He started to make his way towards the portal and that's when Astrid and the others arrived.

"Hiccup! Wait!" Astrid yelled.

Hiccup came to a stop.

"It's too dangerous," said Speedfist. "We can't let you leave like this!"

"I have to rescue, Camicazi," said Hiccup firmly.

"But I'm not even sure this portal leads to the same alternate dimension we came from."

"That may be, but it's a risk I'm willing to take."

"Yeah, well not alone you're not," said Ragnar taking a step forward. "Wait up."

"No," said Hiccup firmly looking at him. "I've already involved Camicazi in this! I'm not going to involve you guys to!"

"Well, I hate to break the news to you, but it's too late for that," said Thuggory. "We're friends. So, we're involved whether you like it or not."

"Yeah, and you can sign me up to go with you to," said Axel.

"And you can't do this without me," said Snotlout.

"And there's no way I'm letting my best friend face horrors unknown with backup," said Ragnar.

"And I your girlfriend," said Astrid looking at Hiccup. "So don't think you're leaving me out of this."

"And the same goes for me," said Heather. "After all one for one and one for all."

"I'm reporting for duty to Captain," said Wartihog.

Only Fishlegs, Speedfist and Agnar were uncertain.

"Can I grab a jacket first?" Fishlegs asked.

Speedfist looked at them with a concerned look. "Look, everyone, I'm all for friendship, but the odds of us returning…"

"Astrid, you stay back. Let me go for you instead," Agnar offered.

"No!" said Astrid strongly. "I appreciate the offer, but I've already made up my mind!"

"Hey, no one is asking you guys to go it's true," said Axel turning towards them. "The odds are slim…"

"But this isn't about odds," Thuggory added. "It's about friends, that's all there is to it."


From the distance Eret and Wolflegs had seen the entire exchange.

"I told you they'll look out for each other," said Wolflegs closing his eyes and folding his arms.

Eret just shook his head. "Unbelievable. They really do and Hiccup kickstarted it all."

"As he always does," said Wolflegs opening his eyes. "Let's just hope it doesn't cost them too dearly."


Hiccup looked at them with a smile. "Thanks guys."

"You better hurry," said Toothless appearing in thin air. "The portal will close soon."

Hiccup immediately turned around and saw that he was right. "The portal is closing!"

"The portal to the alternate dimension is unstable," said Speedfist. "Venturing through it like this would be certain doom. Stand back there's simply no telling what it might do."

Axel then marched up to him. "I'll tell you what we're going to do! We're going to find a way to steady it! Now!"

"Well, uh…" said Speedfist nervously pulling out his PDA. "I suppose if we generated are strong enough power blast we could stabilise it. And the good news is where surrounded by duel energy. Which means we can summon out duel spirits for real."

"Well then let's do it," said Astrid.

"Yeah pull them out, your strongest cards," said Wartihog.

Everyone nodded and pulled out their own cards. Fishlegs, Speedfist and Agnar just looked at them slightly uneasy by this decision.

"You first, Hiccup," said Axel.

"Dragon Knight Toothless!" Hiccup yelled.

"XYZ Dragon Canon!" Snotlout yelled.

"Valkyrie Queen!" Astrid yelled.

"Templar Knight!" Ragnar yelled.

"Machine Queen!" Heather yelled.

"Super Conductor Tyranno!" Wartihog yelled.

"Go, Fossil Warrior Skullking!" Thuggory yelled.

"Volcanic Doomfire!" Axel yelled.

"Don't you worry, Camicazi. No way we're giving up now," said Hiccup strongly.

Suddenly appearing in front of them were there duel monsters.

"Now open fire!" Thuggory ordered.

"Aim right at portal!" Axel ordered.

"Give it all you got!" Snotlout yelled.

"Go and don't hold back!" Wartihog yelled.

There monsters unleashed all the power they could muster aimed it straight at the portal. It was a good effort, but they weren't generated enough power to widen the portal.

"Come on, stabilise," said Hiccup.

Fishlegs and the others just watched the others as they tried to stabilise the portal.

"It's close," said Fishlegs.

"We need more power," said Hiccup.

"Go, Super Vehicroid—Stealth Union!" Fishlegs voice yelled behind them.

Hiccup turned and saw the Fishlegs had just summoned his most powerful monster. "Thanks, Legs!"

"Come out, Water Dragon!" Speedfist yelled.

"Go, Red-Eyes Black Dragon!" Agnar yelled.

The three monsters were summoned the field they assisted the others and fire at the portal. Those three extra tax did the trick and soon a bright light rain down from the sky and struck the portal stabilising it.

"We did it," said Hiccup.

"Something is happening," Eret noted.

Wolflegs rolled his eyes. "You think? What gave it away genius?"

"The portal is stabilising," said Wartihog.

"And then some," said Agnar.

The portal began to widen and soon they were all consumed by the light it produced. And then started to make his way over towards Eret and Wolflegs.

"We've got trouble," said Wolflegs.

A few seconds later they were too were consumed by the light.

Echo had also appeared at proximity of the portal. "Agnar," she said.

Gobber then emerged from the bushes. "Who goes there?"

He then saw Echo consumed by the light and saw that it was heading straight towards him.

Hiccup and the others felt as if they were falling and they weren't entirely certain that they would hit the bottom. However, there was no turning back so the only thing they could do was scream as they fell.
