The riders and Berserkers were in the Berkian training academy with the Skrill. "And flip. You almost got it, Bluebolt. Try one more time." Dagur insisted and the dragon succeeded in doing a flip in the air. The Berserker chief cheered for the reptile and then turned serious, "The Outcasts have dragons too, brother." Hiccup grew concerned, "What? What kind of dragons?" Dagur shrugged, "I don't know. I'd never seen them before today, but they had skinny bodies, big heads, and tore into earth." The Berkian paled, "Whispering Deaths." he said. Toothless growled in response to hearing the species' name.

Dagur noticed the Night Fury's change in demeanor, "Not a fan of them, huh?" Hiccup patted his dragon's head, "He had a feud with a Whispering Death before I trained him. Normally dragon grudges go to the death, but he spared it." "Merciful of him. You all know about dragons. What do we do to get them away from Alvin?" the Berserker inquired. Hiccup began to ponder, "We'll have to use an island that's far enough away from everyone, so that they can live there." he paused, "Actually, I think I remember one from my flights with Toothless." Dagur looked pensive, "That still doesn't help us get them there, though. Unless-well, only Fishy could go in that case-maybe." The riders eyed him with curiousity and he elaborated, "Do you think if we use Dragon Root, we'd be able to move them? Since the other dragons would be rendered unmanageable, we could follow Fishy in my ships."

Fishlegs looked like he had heard the worst possible sentence imaginable, "I-I'd have to d-do what?" Dagur went over to him, "Just lead them to this special island. We'll be right behind you." he said, with an encouraging(or unsettling)smile. The Ingerman boy glanced at Hiccup, hoping he would interject. "This really might be the best option, Fishlegs. Of course, there is the matter of getting on Outcast Island in the first place." Dagur flicked his wrist at the comment, "Easy. My armada can, basically, go anywhere with their numbers. If Alvin plays his cards well, he might not have too many fatalities for his vikings." The riders looked at Dagur like he was crazy and then at one another, "I guess, it's settled then?" Astrid asked, unsure. Her Berkian friend nodded, "Yep, we can head back to Outcast Island."

Fishlegs and Meatlug carried a large piece of Dragon Root to Outcast Island, with their friends trailing behind in Berserker ships. They reached the land mass and it was, eerily, silent. "Careful," Dagur warned the rider, "This could be a trap." Fishlegs nodded and the vikings crept onto the island, looking around them for any sign of life. None was seen. "Are they not here?" Astrid asked, flabbergasted. Snotlout threw his arms in the air, "We came all this way just to find an empty island?" Hiccup glared at him, "We didn't know it was going to be empty, Snotlout." Dagur kept frowning at the cavern, "Let's make sure they're gone." The group entered the cave, weapons drawn in case of ambush. Still nothing. "Uh, guys, this is getting kind of dull." Tuffnut complained. Ruff chimed in, "Yeah, when do we get to explode Outcasts?" Fishlegs, who was already on pins and needles, was growing irritated by them, "Let's be glad they're not here. I'm in no rush to see Alvin." he shuddered.

They found where the Whispering Deaths had been stored, "This is where they used to be." Dagur told the team. The Berkian heir analyzed the craters, "Those are definitely Whispering Death holes. Where could everyone be?" The Jorgenson crossed his arms, "Probably out having fun. Must be nice." Dagur eyed the area more, "Having fun, sure, but they're doing it by killing innocent people with those, wiggly reptiles. They'd have a lot more fun killing guilty people. I know, I will when we see them." he cackled and received a look because of it, "We don't know who they're going after right now. Heck, they might have split up and started attacking both of our tribes. We should head back to Berk and make sure everyone's all right." the chief suggested. The younger vikings agreed and they returned.

The state of Berk was a fine one, fortunately. Dagur went back to the training academy to retrieve Bluebolt and rubbed the dragon's head, lovingly, "We have to return to home. If Alvin's there and I'm not, my people are going to be in trouble." the Berserker told. Hiccup understood, "We have this new thing, though. Terror Mail, we call it. It's when we use Terrible Terrors as messengers. We'll send you one, if we learn anything about where Alvin and his Outcasts went." the boy promised. The two vikings shook hands and Dagur and Bluebolt left the island.

The vessels neared Berserker Island and saw neither Outcast ships nor earth-eating dragons. Confused, Dagur had the vikings pull into the harbor. Bluebolt began to act, strangely, "What's wrong, boy?" The Skrill shook his head to clear his thoughts and flew upwards. Tracking the dragon, the Berserker chief saw him on the top of the island, sitting, happily. "Like it up here only? Weird. All right, we can set up stables for you here. Ya know, you could have stayed in my house." he said in a sing-song manner, "It's just down there. Lot of empty rooms you could play in." The Skrill was resolute and Dagur caved, "Fine. I'll just come up here to see you, if you won't go down with us. Leaving me in that big house. All alone." drama took over his voice, and the dragon laughed at him. He pulled out a piece of paper and began jotting landscape ideas down, "Which do you like better?" he asked the dragon. Bluebolt nudged the one on the right side, "Then that shall be your domicile, friend!" Dagur proclaimed and set to work.

A few months had gone by and the dragon riders were doing their surveillance rounds for Berk. "I don't see any Whispering Deaths, Hiccup." Astrid called out, "Maybe we should try to take them from Alvin instead of waiting." Hiccup frowned, "It would be harder trying to sneak in there and move all of them. They're babies, so even if they'd be willing to listen, they still wouldn't do it very well." Snotlout hovered near them, "Well, can we stop now? There's nothing out here except water, water and oh, more water!" The twins were focusing on an object and interjected, "Oh contraire, mon frère. There's something." Tuffnut noticed. The riders turned to see where the siblings were looking and saw a ship coming towards Berk.

Cautiously, the dragon riders approached the unfamiliar vessel. Recognizing a face, they smiled, "Heather! Didn't expect to see you. What brings you to Berk this time?" Hiccup inquired. The girl looked worn and saddened, "Alvin again. He was spotted near our island, but didn't attack, directly. These weird dragons with long bodies appeared and just started eating the island! Only the three of us made it out alive." she gestured to her parents. The two elder vikings were alive, but just barely, clearly having been injured during the escape. "Astrid take her mother, I'll grab her dad and we can bring them to Berk faster." The viking complied and, gingerly, scooped the woman onto Stormfly's back.

The parents were brought to Gothi for healing. "What is she saying?" Heather inquired, as Gothi wrote in the sand. Gobber's face went dreary, "She says that they might be able to survive these wounds, but will need particular care." The healer handed the young girl a list of things that she needed to do, daily. "Heather, I'm so sorry that this happened." Hiccup apologized. Fishlegs came over, "If you need anything, let us know. Of course, you're welcome to stay here." The Berkian heir nodded.

Hiccup went to get a Terrible Terror. "What are you doing?" Astrid inquired. "I'm contacting Dagur. He needs to know that this is what Alvin was doing when we found their island empty. Heather, about how far is your island?" The girl thought, "Um, a week's travel maybe. We left before the Outcasts did, so they might still be on their way." Hiccup pondered, heavily, "If he's still on the way, maybe we could get Dagur to come here and help us formulate a plan." He arranged the letter on the little dragon and it flew off to pursue its mission.

Dagur was in the new Berserker arena with Bluebolt, practicing more accurate blasts. "You have to aim a little ahead of the mark, so that when you're flying, it'll still hit." he instructed. The Skrill listened to the recommendation and hit the next target, smiling afterwards. Dagur did a Berserker cheer and heard the sound of small wings flapping. Eying a Terrible Terror, he remembered. "Oh, yeah. The whole mail thingy." he undid the message from its body, "Thanks little dragon. Um, want some fish as payment?" This brightened the Terror and he wiggled, happily. Dagur tossed a piece of trout into the reptile's mouth and it flew back to Berk. The Berserker read the note and was unsure of what to do. "If I leave, I'd leave us vulnerable to attacks. Also, if I stay and Berk gets attacked, I won't be able to help them." he paced back and forth, until Bluebolt landed in front of him, trying to calm him down.

Dagur stared at the dragon, "If something happens, Bolty, will you make sure everyone gets out. I'll leave Vorg with you to help." The Skrill nodded, seriously. Dagur gathered Herald and some Berserker ships with him to travel to Berk. "Brother!" he called out, seeing Hiccup. He trapped the smaller boy in a bear hug, "Glad to see you're all right still." he told him. "Yep, we're fine, but our friend Heather lost her entire island. Her parents are, badly, wounded too." The chief went grave, "Her name's Heather?" Hiccup was surprised about that being the thing that stuck out most, "Um, yeah. And her village got destroyed." Dagur's focus went off of the Berkian and wandered, aimlessly, "That's a popular enough name. Could be anyone." he thought. "Eh, w-what kinds of injuries? From the falling apart island, or did the dragons, directly, attack them?" Hiccup began to lead him towards the trio.

The adult vikings were still in poor shape and their daughter was by their sides. "Heather, this is Dagur. He's the Berserker chief and the ally that I mentioned to you earlier." Hiccup introduced. Heather stood up, "Chief? Sorry, but I just assumed that you'd be older." A silence occurred when Dagur could do little more than stare. Toothless nudged him, bringing him back to the situation, "I get that sometimes." he said, rushedly, then added, sincerely, "Really sorry to hear about your parents and island." Heather's eyes lowered, dejectedly, but brightened when he spoke again, "These are wounds from the debris. I know how to help with that." "Really?" she asked, in disbelief. He nodded, "Berserker island has a hollow center. A lot of vikings got caught in it crumbling, so we know a thing or two about healing those wounds."

Heather handed the chief the list Gothi had given her, "This is what I've been instructed to do." Dagur looked over the notes, "Good, but you'll need to use some Yarrow tea, simple exercises to keep their muscles working, and something to keep their spirits up." Heather sighed, "That last one doesn't seem possible. We lost everything." The Berserker shook his head, "Not each other." he pointed out. She conceded to that, "True, but why does it matter trying to be happy about all this? Wouldn't the more traditional methods help just fine by themselves?" Dagur handed her back the letter, "The spirit is a strong thing. If that's really strong, you can be unstoppable. Contrarily, you could have all the resources in the world, but be without a fighting soul and you'd die. Just my opinion, though."

Heather seemed open to the idea of staying positive and Dagur and Hiccup left to go speak with Stoick about their battle strategy. Dagur was quiet the entire walk there, just thinking. Hiccup decided not to interrupt whatever was going on in his friend's mind and instead went along, silently. "Is it possible? No, that's so unlikely. But anything can happen. Ugh! She has the same traits, but how strange would that be? Come on, try to stay focused here." the Berserker, mentally, chastised himself, "Well, I suppose, that I'll have to wait and see with Heather. I'll need more information before jumping to conclusions. Ooh, I hope we get kill Alvin, quickly, I can't stand this uncertainty!"
