Heather and Windshear were flying out on their normal routine to check out for any Dragon Hunter ships.
"Alpha quadrant chescks out. Nothing but water and-" Heather was saying when Windshear interrupts her and Heather pulls out her spyglass and sees there's a ship that has no reason for being there.
Let's go get a closer look, girl." Heather says and the two land on the ship.
Heather and Windshear search the ship and can't see much because of the fog and see nobody on board.
"Abandoned. Let's get out of where." Heather says when they hear someone belowdeck screaming.
Heather pulls out her axe and walks in to see what that noise was and is followed by Windshear.
"Ugh, what is that smell? Windshear, torch." Heather says and Windshear lights the torch and they walk down to see hundreds of Vikings dead.
One of them grabs Heather's hand and scratches her arm and the two run out onto the deck.
Windshear looks to Heather worried about her Rider.
"I'm okay, girl. It was just a scratch." Heather assures her dragon before they leave the ship.

Back at the Edge, Hiccup was working on new gear and places on glasses as Toothless sparks the metal.
"Interesting material. Seems organic in nature." Fishlegs comments on the glasses.
"Deathsong amber, hammered thin. They're strong enough to stare straight into the eyes of a Flightmare." Hiccup tells him.
"Fascinating. May I?" Fishlegs asks and Hiccup hands them to him.
"I insist." Hiccup says when they see Heather is back. "Heather, you okay?"
Heather doesn't answer and Hiccup sees her face and starts to worry.
"What's wrong? Did you see something on patrol?" Hiccup asks.
"I found a fishing boat." Heather tells him. "It was just drifting out there. We went to take a closer look. But what we found inside it was...bodies. Their skin were all pale and green. We got out of there as fast as we could."
"Hiccup, pale green skin? I hate to be the harbinger of doom, but..." Fishlegs says.
"I know what you're thinking, Fishlegs, but-" Hiccup was saying but Fishlegs says it.
"The Scourge Of Odin."
"Okay! Let's not just throw that word around too loosely, because-"
"Wait, back it up. Did he say Scourge of Odin?" Snotlout asks.
"Yes, but there's no reason to panic." Hiccup tells him.
"Right, no need to panic. The Scourge of Odin. Just the plague that tore through the archipelago centuries ago, wiping out entire Viking villages! Yeah, why would we worry about that?" Snotlout asks as he starts to panic and covers his mouth. "Quick, Hookfang! I need a mask for my mouth."
"Well, that's a long time coming." Tuffnut says.
"Very funny. I already feel short of breath." Snotlout says.
"We must burn our clothes!" Ruffnut tells them.
"No, no, no, no, no. No need to panic. I've got the answer." Tuffnut assures everyone. "Wait for it. Bing!" He says and pulls out moldy bread.
"Moldy bread?" Astrid asks.
"Once I had a really bad cold. So, I decided to eat some moldy bread. So, I decided to eat some moldy bread. Don't ask me why, because I don't know. But, boom! Instantly cured." Tuffnut explains to them. "You scoff now, but one day, science will recognize my genius. They called old crazy uncle Henrik crazy."
"He is crazy, Tuffnut. He married his own beard." Ruffnut reminds her twin.
"Okay, bad example. Let's go with your clothes burning plan." Tuffnut agrees. "We'll keep them on you, just to be sure. Barf! Belch!"
"Let's not jump to conclusions and set ourselves on fire, eat moldy bread or hyperventilate." Hiccup tells the team as Snotlout is breathing into a mug.
"Snotlout, you can't catch the Scourge of Odin by breathing it in." Fishlegs informs him.
"I knew that." Snotlout says and tosses the mug.
"There hasn't been a single case of the Scourge for centuries. Plus, Heather got out of there right away." Hiccup says as he walks up to Heather. "Are you sure you're okay?" He asks.
"Yeah, I'm fine." Heather assures him.
-
Later that night, Hiccup was finishing up some advancements to the dragonfly when Windshear comes in and scares Hiccup and his sleeping dragon.
"Windshear?" Hiccup asks as she runs out and Hiccup follows her into their hut and sees Heather out of bed. "Heather?"
"Hiccup? What's going on?" Heather asks, sounding tired as Hiccup approaches her.
"Well, I was finishing up at the forge and Windshear seemed worried, so." Hiccup explains when Heather starts coughing and Hiccup sees that her hand is scratched.
Hiccup brought in Fishlegs and he looks over Heather as Hiccup just paces.
"Hiccup, will you stop the pacing?" Heather asks of him and Fishlegs brings Hiccup out of the hut.
"You saw that scratch, right?" Fishlegs asks him.
"She said it's nothing." Hiccup says but doesn't think that's the truth.
"It's not nothing. All the signs are there." Fishlegs tells him.
"Okay, lets assume for a second that you're right. What's the cure?" Hiccup asks him.
"I'm not sure. The only thing I know is that the Scourge moves swiftly, overtaking its victims in less than three moons." Fishlegs informs him on what he does know.
"One Moon has already passed."
"I know. Snotlout is on his way back from Berk with Gothi's notes. Hopefully they'll tell us something more." Fishlegs tells him as Snotlout returns and Hiccup snatches the notes.
"Look, in Gothi's notes, there's a cure for the Scourge of Odin." Hiccup says and keeps reading. "A green solution made from the saliva of a Buffalord dragon."
To that news, Fishlegs starts to look worried.
"What?" Hiccup asks.
"It's just..."
"There aren't anymore Buffalords." Astrid breaks to him. "They were all hunted to extinction during the Scourge's last outbreak."
"No...there is one." Heather says and they look to her as she tries standing up. "One of the islands we explored a while back. Me and...Windshear spot it..." She explains before she faints and Hiccup catches her.
They start looking through the maps of everywhere that they have traveled and Heather's drawings on the dragons inhabited there.
"We found it, Hiccup." Fishlegs says as they see where Heather ran into it.
"We have a location. Let's hope to Odin it's still there." Hiccup prays.
-
The team all leave and Astrid offered to stay with Heather while they all left to the island.
Hiccup followed Heather's maps and make it to the island and see nothing on the island.
"Now, these dragons were supposedly hunted to extinction. So if there are any left, they will have developed a wariness towards humans." Hiccup warns them.
"Which means we have to move quickly." Fishlegs adds.
"And remember, we have less than two moons to find this dragon and bring the cure back to the Edge." Hiccup finishes.
They all start looking and they've spent the whole day searching and have come up with nothing.
Hiccup and Toothless we're flying and landed to get some water when Toothless smells something and starts following it.
Hiccup follows his dragon and finds a pile of dragon dung. He gets the rest of the gang to their location and Fishlegs looks over it.
"Large size. Unusual coloration." Fishlegs says and dips his hand into it and smells it. "Vegetarian diet. Not the remnants of any dragon I'm familiar with. And I know my dragon droppings. It's fresh, Hiccup. Last couple of hours, this dragon is still somewhere on this island."
"And might I add, a very distinctive bouquet. Sore of herbal. It's quite nice." Tuffnut says as he smells the dung.
"Ew." Snotlout comments as Fishlegs does the same. "Double ew."
"Well, if it's here, I think I might know how we can find it." Hiccup says as he pulls out a sack. "This dragon tracking equipment. Now, it's not field tested, but it's worth a shot." He says and pulls out Flightmare algae and drops it to reveal the tracks of the Buffalord. "Hopefully, a dragon this large doesn't move too fast."
They start following the tracks trough the island until the tracks run out.
"Now what?" Snotlout asks.
"It must have taken to the air." Hiccup guesses and pulls out a magnifying glass to look closer and finds dragon scales. "This way. Let's move!"
They keep walking until the morning sun comes out and Hiccup puts the glasses on to see past the glare.
"Nothing! How could there still be nothing?" Snotlout asks.
"No, not nothing. Look closer." Hiccup says and passes the glasss to Snotlout and he sees the dragon.
"A Buffalord. Alive!" Snotlout cheers and accidentally moves the glasses and gets hit by the sun rays.
Hiccup approaches the dragon slowly and cautiously.
"You guys distract it, and I'll get its saliva." Hiccup tells them.
"Be careful m Hiccup. We know nothing about this dragon." Fishlegs reminds him.
"Ageeed. But we need to make this quick. We're running out of time." Hiccup says as they only have today to save Heather.
He approaches the dragon as it's eating and everyone runs as it yawns at them.
Hiccup gets sone of its saliva in a container but sees it quickly dries up.
What do we do now?" Fishlegs asks him.
"We rope him and take him back to Dragon's Edge." Hiccup tells them and they start roping him and Toothless purrs to comfort it.
"It's remarkably docile for a dragon of its size, almost yak-like." Fishlegs tells them.
"No wonder it was so easily hunted." Snotlout mocks the dragon. "You gotta toughen up there, Buff."
"Aww, he's kind of cute." Ruffnut comments on him.
"Hiccup, can we keep him? I promise I'll walk him and feed him and stuff." Tuffnut promises. "We already know his poop doesn't smell. And he doesn't even act like it. Not like Ruffnut, who acts like her poop doesn't smell."
"We need to get him back to Heather." Hiccup tells them as they start to leave and the Buffalord starts to follow them.
As they start flying further away from the island, the Buffalord starts to inflate and spikes coming out of his side.
"Guys? I think something's up with the Buff." Snotlout says as they all avoid the spikes and the Buffalord starts spraying fire around him and breaks the rope.
"I knew I shouldn't have told him to toughen up. Me and my big mouth." Snotlout admits as they release the Buffalord as he returns to the island and goes calm again.
"Okay, what was that about?" Snotlout asks.
"He appears to be fine, so long as he's on his island." Fishlegs guesses.
"If we can't take the Buffalord to Heather, bring Heather to the Buffalord." Hiccup says and sends a Terror Mail to the Edge for Astrid.
-
It took her a while, but Astrid made it with Heather and Hiccup carries her as she's getting weaker.
"Just rest. We're gonna beat this." Hiccup promises her. "You just have to keep fighting, and hold on." He says as he places her near the Buffalord. "You need to stay with us. I can't imagine a world without you in it."
Hiccup makes it back to the Buffalord and takes its saliva and quickly makes it back to Heather and nothing's happening.
"Maybe it takes some time for the antidote to work." Fishlegs suggests.
Windshear purrs and places her head hear her rider, worried as Toothless is comforting her himself.
"It says the green solution will cure the Scourge." Fishlegs says and Hiccup sees what's wrong.
"The saliva is clear. What does to mean green?" Hiccup asks and Astrid sees the twins eating the Buffalord's food.
"What are you two dumb bells doing?" Astrid asks.
"Hey, people deal with stress differently, okay?" Ruffnut informs her.
"And we're eating what the Buffalors eats, because, Hey, who doesn't want sweet smelling droppings?" Tuffnut asks and they watch as their saliva starts turning green as they're eating it.
"Wait, Hiccup..." Fishlegs call's and Hiccup sees it.
"The herbs. It must be what the Buffalord eats, mixed with its saliva that crates The antidote." Hiccup pulls together.
"Which would Stand to reason why it wouldn't leave the island. It can't be away from the herbs it eats." Fishlegs adds.
"So we just need it to eat the herbs to create the green solution." Hiccup finishes and looks to Heather who's looking worse by the minute. "Hang in there, Heather. Just a little longer please."
Snotlout starts to lead the Buffalord to the small field of herbs.
"Come on, you big Buff. You worked up a healthy appetite trying to kill is earlier. So eat!" Snotlout tells him.
"Come on. Keep going. Eat it up." Hiccup says and they see its turning green when a net is fired and wraps the Buffalord up and they look to see the Dragon Hunters.
"Viggo!" Hiccup shouts, seeing him as his men surround the dragon.
"Hello, Hiccup. Thank you so very much for this gift." Viggo tells him. "I do apologize that you won't be able to use it to save your friend."
"But How? There's no trace of this island anywhere. How did he find it?" Fishlegs asks.
"Who cares? We've been dying for a little action." Snotlout says as they take to the air.
"Let's make this count, bud." Hiccup says as they fly in and start attacking them to free the Buffalord and they try to hit them.
"Hiccup, I can't get a clean shot." Snotlout tells him as the twins are taken down.
"Pull up, riders. We can't risk hurting the Buffalord." Hiccup tells them. "Viggo, release that dragon. You have no idea what you're doing."
"Oh, I beg to differ, my dear Hiccup. I'm keenly aware of my actions. This dragon is wsceedingly unique. It will elicit a considerable bounty on the open market. You should have well enough alone, Hiccup. My fishing boat was no place for you or any of your riders." Viggo informs him.
"Your fishing boat?" Hiccup asks as they realize he placed the boat there for them to find the Buffalord.
"It's simple, really. Supply and demand. I knew where to get the supply, if I could only generate the demand." Viggo says and looks to Heather who's clinging on to life.
"You're a monster!" Fishlegs states.
"Fishlegs, I'm shocked. I'd have thought you were above name calling. Monster? No. Savvy businessman? Indeed." Viggo replies.
"And what if the dragon was extinct?" Hiccup asks of him.
"I tend not to dwell on the what if's, my boy. Leaves you barren." Viggo informs him.
"What are we waiting for? Let's take this psycho out already!" Snotlout says and Hiccup gets ready to blast him white Ryler raises a sword to the dragon's head.
"I would think twice about your actions, Hiccup." Viggo states.
"And your profits?" Hiccup asks.
"Like I said, business is business. This? Oh, it's a loss I'm willing to incur. Question is, are you?" Viggo asks him and once again looks to Heather who's shuttering.
"Okay, Viggo. You win, take him. But leave us with what we came here for, the Scourge antidote. Buffalord saliva. I'm not leaving without it." Hiccup promises him. "That's a loss I'm not willing to take."
"No..Hiccup...don't do this...not for me.." Heather begs of him weakly.
"Do we have a deal? Or are we both leaving here empty handed? Your call." Hiccup tells Viggo.
Viggo decides to allow it and calls off Ryker as Hiccup takes the saliva.
"I've truly missed our time together, Hiccup. My brother leaves something to be desired in the repartee department." Viggo says as Hiccup doesn't even face him and looks angry. "My boy, don't look so morose. It takes all the fun out of it. All's well that ends well." He says as Hiccup takes the antidote to Heather.
As soon as she takes it they see it work as the color returns to her face and she is able to stand up and hugs Windshear as she's happy her Rider is going to be okay.
"I'm afraid our time must end, Hiccup. We will continue our contest in due time." Viggo promises him and leaves with the Buffalord.
"He won't get far. Let's go after him." Tuffnut says.
"No. Stand down. We agreed to let him leave the island with the dragon. And tha exactly what we're gonna do." Hiccup tells them.
-
On the Dragon Hunter ship, Viggo is watching the island and is expecting to come in.
"The beast has been secured in the transport ship." Ryker tells Viggo.
"Excellent. A bit disappointing. The again, he is a man of his word. Something to admire about that." Viggo comments on Hiccup when the ship starts coming apart as the Buffalord is tearing it apart and setting it on fire.
"What's it doing?" Ryker asks.
"Hiccup!" Viggo realizes as he knew Hiccup must've known this would happen. "Release it! Release the beast!" He tells the men as the Buffalord flies off and they set it free as it flies off and the ship begins to sink.
The Dragon returns to the island and the riders see he's going to be okay.
"Well, there's only one thing left to do." Hiccup says as they fly off to find the fishing boat.
-
"There do I see my father, my mother, and my brothers and my sisters. They bid me take my place among them in the halls of Valhalla where the brave shall live forever." Heather says as they all shoot a flaming arrow, and watch as it starting to burn Viggo's ship down and they know they're safe as everyone flies back to the Edge, leaving Hiccup and Heather.
"What are you thinking about?" Heather asks him.
"This might be just the beginning." Hiccup tells her. "Something Viggo said about knowing where the supply was. You don't think he could have unlocked the Dragon Eye, do you?"
"How could he have done that? He doesn't have a Snow Wraith key." Heather reminds him.
"Well, he found the Buffalord on his own. And we need to find out how." Hiccup replies.
"Thanks for going through all this for me." Heather says to him with a smile on her face.
"You'd have done the same for me in a heartbeat." Hiccup reminds her.
"I can't imagine a world without you in it, either." She admits and the couple flies off back home to come up with a way to stop Viggo.
