Back in the land of Draconia, Ruby was relaxing in his cave. He sighed peacefully. His mate Harmony, a white Whippertail, was off hunting.

Eider yawned, blinking his sleepy eyes open. He was a young Blackfang/Whippertail hybrid who was orphaned at a young age. He was taken in by Ruby and Harmony, and they acted as his guardians. Although after all that they have been through over the years, Eider was growing to see and love them as parents and not simply guardians, as Ruby and Harmony were starting to see and love him as their son. Eider was currently beside Ruby, awakening from a nap.

"Good morning", Ruby said cheerfully

"Good morning", Eider yawned as he got up to stretch himself

"Where's Harmony?", the young dragon asked.

"She went hunting a while ago. She should be back soon", Ruby answered.

At that moment, an orange Hermes Dragon landed in front of their cave. Its eyes scanned the cave, looking for Ruby. At the sight of the orange reptile, Ruby got up and stepped forward.

"Can I help you?", Ruby questioned.

"Yes, are you Ruby?", the Hermes dragon asked.

"I most certainly am", Ruby responded.

"I have a message for you. It is from the king and queen themselves", the little dragon explained as he held out his front paw. Attached to the ligament was a scroll.

Ruby detached it and unraveled it, reading it aloud:

'Ruby, I send this message with the utmost urgency and importance. Serenity is in danger! I need you and your mate to come to Berk immediately. -Aurora'

As he concluded, a grim expression was etched onto his features. He looked toward Eider who equally looked just as distressed.

"Thank you. You are dismissed", Ruby expressed to the Hermes Dragon with solemn.

The Hermes Dragon gave a nod of understanding, then took its leave.

"When are we leaving?", Eider asked he started to put on his armor.

"As soon as Harmony gets back", Ruby said, also putting on his armor.

Just then, the dragoness in question flew in the cave, carrying a freshly killed deer. When she noticed the two males with the armor on, she knew something was wrong.

"What's the matter? What's going on?", she asked worriedly as she placed her kill in a corner of the cave.

"My ward, Serenity. She is in trouble and the king and queen demand that we meet them at Berk immediately", Ruby addressed.

Harmony sighed, "Well, we can catch some fish then, on the way".

Since Harmony was the only dragon to not have armor, the three took off as fast as they could towards the Viking village.

A day and a half passed before the three dragons landed in Berk. Once they settled on the ground, they scanned the many vikings and dragons for their king and queen. Just then Aurora landed in front of them. Before they could say anything Aurora spoke. "Follow me". Aurora then spread her wings and took off, with Ruby, Harmony, and Eider following.

They landed inside the arena, where the rest of the group was waiting.

"So what happened to Serenity? Is she hurt?", Ruby asked, panicking.

"Calm down Ruby. As far as we know, she is alive, but captured"

"WHAT?! Who in their right minds would capture her? She wouldn't hurt a soul", Ruby exclaimed.

"My son and Tenor's mate captured her", Re stated

"WHAT?! You're telling me that her mate, as well as his dragon captured Serenity? Why would they do that to her?", Ruby implored.

"Because they are being forced to. Because a dragon named Hael has Chris and Windwalker under his control. They ambushed us and captured us. But they also left a note behind, saying if we wish to ever see them again, we needed to talk to you and bring you and your mate to your island. Now tell me who this Hael is", Re growled.

Ruby tensed at the mention of Hael. He looked around the arena and sighed. "Hael is a female Changewing. She was banished from Changewing island for reasons she didn't share with me. She made her way to Draconia and settled in the forests near my cave, right after I left my home. I found her and after a couple of years, we became good friends, as we both had no one else at that time. But then, Serenity came into my life and she changed it for the better. Hael, not fond of humans, grew mad at me for befriending and protecting a human child. And that I should spend more time with her instead of a human. However, I wasn't going to abandon Serenity! I grew to love her! I told Hael that if she can't accept Serenity, she couldn't accept me either. Hael didn't like that and flew off. That was the last I ever heard of her. After I was brought back from the dead, I decided to get on with my life. Now I got a beautiful mate, and we are fostering a hatchling together. I simply buried Hael in the past. I figured she would be gone from my life forever".

"Well that would explain how Chris and Windwalker are under control", Hiccup commented after Aurora finished translating for the vikings.

"True, but I want to know how they can break out of Hael's hypnosis", Re asserted, "I also want to know where this island is. Hael said 'our island', so that led me to believe that only you and Hael know where it is".

"The island she is talking about is located east of Draconia. It is much like Dragon Island, except it's full of tropical life. As for breaking out of a Changewing's hypnosis, I can't help you there", Ruby said.

"Berk's book of dragons has nothing on that subject either", Fishlegs interjected.

"Then let us ask a Changewing then", Re declared before spreading his wings and taking off.

"Stay here, I will be back", he boomed before zooming out of sight.

An hour and a half later, he landed inside the arena with a Changewing beside him.

"Everyone this is Rellyt. He is the leader of the Changewings. I filled him in on our crisis", Re announced.

Rellyt bowed and was about to speak but instead growled lowly and assumed a fighting stance.

"I'm sorry your majesty, but I will not do anything when the egg-stealer is here!", Rellyt hissed, indicating to Snotlout.

"Stormfly, get Snotlout out of here", Re ordered.

"Wait, what? You can't jus-AAAHH!". Snotlout didn't have time to finish his remark as Stormfly grabbed him by his shoulders and flew out of the arena.

"Thank you my king", Rellyt said bowing.

"Now tell us how a Changewing's hypnosis works", Re uttered.

"Well, it works the same way a Bewilderbeast or a Queen Dragon can control their nests. We just force our influence on another dragon, but we can only do that if they are staring into our eyes. Once we have them under our control, their eyes turn slightly red instead of turning into slits", Rellyt described, with Re translating for the other vikings present.

"After you hypnotize them, are they completely under your control?", Hiccup asked.

"Hmm, I am not so sure, human. It depends"

"How so?", Valka pressed.

"Well, the longer they are under a Changewing's control, the harder it is for them to break out of it, and the redder their eyes will be.

"But they can break out of it, yes?", Aurora asked, hopeful.

"Yes they can, but they don't have much time", Rellyt answered.

"What do you mean they don't have much time?", Tenor asked with worry.

"We Changewing's use our hypnosis as a last resort. Unlike Bewilderbeasts and Queen Dragons, the effects are deadly for whoever is under a Changewing's influence. At first they seem okay, but their mental health deteriorates the longer they are under hypnosis. Eventually, they either go crazy or, for a lack of better words, 'burn out'."

Everybody was in shock at the news.

"That's awful", Aurora remarked.

"That's why we rarely use it. It only works temporarily; with us having to hypnotize more people and leaving our subjects crazy or, you know", Rellyt sighed. "Tis' a burden we Changewings have to bear".

Rellyt turned to back to the group. "If we are talking about the same Hael, then you all are in deep trouble. She is a selfish dragon and does not care for other people's well-being. She abuses that power and uses it casually, fully aware of the consequences of our ability. We told her to stop but she would not listen, so we captured her and were scheduling to take her hypnosis away, but she escaped and left some of our brothers and sisters 'blinded'. We haven't been able to track her since", Rellyt continued grimly.

"How can you take away another Changewing's hypnosis? And what do you mean by 'blinded'?", Astrid inquired.

"If another Changewing hypnotizes another Changewing, the oppressed dragon will use their hypnosis as a means of defense instinctively, to avoid being under control. But that is the ultimate cost. It takes away their hypnosis forever, rendering them 'blind', for a lack of better words", Rellyt asserted, regarding Astrid.

"So she never was banished", Ruby muttered.

"No. We would never let a Changewing who abuses that ability out on the loose. That's one of the reasons why we Changewings are all located on one island. If one of our own decides to become a tyrant, we can easily correct the issue", Rellyt replied.

"So how does one break out of a Changewing's hypnosis?", Tenor queried.

"The influenced dragon must have a strong sense of nostalgia, in order for the hypnosis to be broken"

"Nostalgia?", Eret cried.

"They need to be reminded of the past, typically of memories that bring them great joy", Hiccup explained.

"The human is right. If the influenced person is reminded of a happy memory, it subconsciously reminds them of their true self, of their inner strength. It makes them yearn for what they once were. Only then can the hypnotized person break the hypnosis", Rellyt stated.

"Okay, that's simple enough. We can do this!", Re voiced.

"I hate to say this, but it is not that simple, your majesty", Rellyt said timidly.

"Oh what now?", Re groaned.

"The reason it gets harder to break out of our hypnosis is because the afflicted person gets bombarded with constant negative emotion and memories. It clouds their mind and their judgement, with the sound of their master being the only temporary alleviation. That's why the subjects are so eager to carry out their master's orders, because they want their negative thoughts to be relieved; the longer the person is hypnotized, the stronger the negative feelings and the more fervent the subject becomes", Rellyt responded.

"What if another Changewing were to take control of the hypnotized person, and then release them from the hypnosis?", Aurora wondered.

"That will not work. The stress of having two foreign influences inside the afflicted mind would be fatal. It would cause the body harm, speeding up the process of rendering them crazy or 'burnt out'.", Rellyt negated, shaking his head.

Aurora hung her head in shame. 'Well that explains why Windwalker started coughing up blood', Aurora though sadly.

"Thank you for your time Rellyt. You may go now", Re dismissed.

Rellyt nodded before taking his leave. Re was deep in thought, conjuring up a plan.

At long last Re sighed, defeated. "It's no use. The only way we can ever see them alive and well is if we comply with Hael's demands".

"No! There has to be some other way!", Ruby barked.

"She has our wings tied. Either way, she basically wins. If we don't comply, Chris, Serenity, and Windwalker will all suffer a terrible fate. If we do comply, you and Harmony will surely suffer as well", Aurora added.

The group stood there, frightened of what was in store for their group, and frightened of what was to become of the Night Fury, her rider, Ruby, Harmony, and the dragon healer.
