Bruni sat on a rock waiting for Elsa, Hiccup, Heather, Anna, Olaf, and the dragons to catch up.
"Ah, ah, ah, ah!" Elsa sang out into the wilderness, hoping for the voice to answer back.
"Arhaagh!" Hiccup roared, trying to receive a call back from his grandfather to find out where he is.
"Ah, ooh, ah, ooh!" Olaf called out after the couple, Anna, Bruni, and the dragons jumped at the sudden burst of sound as he's singing off key.
"Ah, ah, ah, ah!" Elsa called out and Hiccup roared again.
"Ah, ooh, ah, ooh!" Olaf replied the dragons and Bruni grumbled as the Night Lights cover their ears as best they can.
"Hey, Olaf. Maybe just do it quietly," Anna suggested as the dragons nodded in agreement.
"I agree. Hiccup hasn't got the right pitch." Olaf whispered back to her and the dragons shook their heads.
Gale flew past them and twinkled, the dragons crooned in response.
"Hey, Gale's back." Olaf happily announced as the wind spirit circles them.
Gale flew over to Hiccup and Elsa twirling around the two magical beings, before flying over to a hill making a flag attached to a mast flap.
Elsa and Anna ran up the hill, Hiccup, Olaf, and the dragons following close behind.
When they reached the top the sisters stopped and gasped, there laying tipped over was an Arrendallian ship.
The others came up behind them, looking down on the wreckage and Hiccup could tell exactly whose ship it was.
"What is it?" Heather asked, looking confused at the wreckage.
"Mother and father's ship." Anna exclaimed still gripping Elsa's arm.
"How? This isn't the Southern sea." Hiccup pointed out as Liry stood next to Elsa.
"No, it isn't." Anna stated as Elsa ran down the hill towards the ship.
"Oh yeah, we should definitely go check out the abandoned shipwreck." Hiccup deadpanned to himself while walking down the hill with Heather and the dragons and Olaf.
The sisters walked into the ship and looked around at the scatted wood, silt from the sea not far away was beginning to swallow the sulking hull.
Hiccup and Olaf sauntered in behind the girls, the craftsmanship was incredible.
"Why is their ship here? How is it here?" Elsa asked moving a plank of wood.
"It must have been washed in from the Dark Sea." Anna answered back rummaging through a trunk with Stormfly.
"What were they doing in the dark sea?" Elsa questioned while she and Hiccup looked through a set of shelves.
"I don't know." Anna replied as she pulled back a curtain.
"How did the ship get through the mist? I thought only we could." Heather wonders.
"Unless nobody was on it," Olaf stated, while looking at the hole in the ships hull.
"There's got to be something here to tell us why they were in the dark sea," Hiccup announced while holding Elsa's hand.
"Wait, look around." Anna said and runs to the wall. "Every Arrendallian ship has a compartment that's waterproof." She began checking the walls and every shelf.
"That's very clever." Olaf stated while picking a few things up.
"Wait, why don't they just make the whole ship waterproof?" Hiccup queried while he was pressing his fingers against the walls.
"You said it, not me." Heather agreed while she was searching.
Anna began pushing a cupboard and Elsa was checking a set of shelves, Hiccup ran his fingers across the side of a bench and a flap opened carrying a long metal cylinder.
"Ah, guys I found something!" Elsa and Anna rushed over and took the cylinder.
Anna opened one end and pulled out a piece of parchment, she unravelled the paper to reveal a map and chart with a foreign language written on it.
"What language is this?" Heather asked while Anna passed it to Hiccup.
"I don't know, wait this is mother's handwriting," Elsa answered indicating to one of the corners.
"The end of the ice age, the river found but lost, the life-givers cave, magic source. Elsa's source?" Anna read and Elsa grabbed the chart as she and Hiccup tried to make sense of the writing.
"It's a map. They travelled North and planned to cross the sea to..." Anna followed her parent's markings until she reached a hand-drawn section.
"Attahallan?" Elsa and Hiccup both held the map in shock.
"It's real?" Anna looked at Elsa and Hiccup trying to find answers.
"Atta-who-what?" Heather asked, confused about what they're talking about.
"Attahallan, it's a magical river said to hold all the answers about the past." Anna sat back down.
"Reinforcing my theory that water has memory." Olaf commented as Elsa got up.
"Water has memory." Elsa kneeled down on the floor and placed her hands on the wood releasing her magic.
The water from inside the wood flowed out of it and began forming a statue in the centre of the ship's rear.
"Elsa?" Everyone watched with curiosity.
"I want to know what happened to them." Elsa closed her eyes and concentrated on the memories the water held.
The statue formed and the sisters looked at it as their parent's voices echoed from it.
Iduna and Agnar were hugging as waves roared around them until they were gone, Elsa ran out of the ship with Liry following her rider.
"Elsa, wait!" Hiccup jumped down from the platform they were on and rushed out after her with Anna.
Olaf stayed to look at the statue with the Night Lights, he wasn't all that sure. Elsa leant against a rock, Liry was trying to comfort her as Anna and Hiccup found her sobbing and rushed to her.
"Hey, hey, what are you doing?" Anna asked her, Hiccup had enveloped her in a hug and the Queen was now sobbing into his chest.
"This is my fault, they were looking for answers about me." Elsa continued to sob into Hiccup's chest.
"Hey, listen to me, you are not responsible for their choices Elsa." Hiccup held his girlfriend's chin up for her to look at him.
"No, just their deaths." Elsa pulled out of the hug and started to walk away.
"No, stop. Yilana asked why would the spirits reward Arendelle with a magical Queen. Because our mother saved our father, she saved her enemy." Anna held Elsa's arms and looked her in the eyes.
"Elsa, her good deed was rewarded with you, you are a gift." Hiccup held Elsa's hands and smiled at her.
"For what?" Elsa looked away from both of them.
"If anyone can resolve the past, if anyone can save Arrendale and free this forest, then it's you two." Anna grabbed Hiccup's hand.
"Elsa, listen to us, we believe in you, I believe in you more than anyone or anything." Hiccup held Elsa's hand tighter.
Elsa released their hands and walked away a bit, she needed to continue on this mission alone.
"Honeymarron said there was a fifth spirit, a bridge between the magic of nature and us." Elsa turned to the two of them and explained.
"She also said that the Foreverwing was the protector of the spirits." Hiccup replied back to her.
"That's who has been calling me from Attahallan." Elsa told them, Anna stepped forward. "The answers about the past are all there."
"So, we go to Attahallan?" Heather asked, Hiccup suddenly felt the pain shoot up through his spin but kept quiet.
"Not we, me." Elsa told them.
"What? Elsa..." Hiccup tried to reason with her.
"That dark sea is too dangerous for all of us." Elsa pointed North and to the dragons.
"No, no, we do this together. Remember the song." Anna announced, trying to tell her sister.
"Go too far and you'll be drowned, who will stop you from going too far?" Hiccup commented, he wasn't going to let her go by herself.
"You said that you both believed in me and this is what I was born to do, what we were born to do." Elsa pointed to Hiccup.
"I...I don't wanna stop you from that. I don't wanna stop you from being whatever you need to be. I just don't want you dying..." Anna blurted out, Olaf and the dragons gasped. "I don't want either of you dying, trying to be everything for everyone else to, don't do this alone. Let me help you, please, I can't lose you guys." Anna told both Elsa and Hiccup.
Hiccup and Elsa hugged Anna as did the dragons.
"I know, I can't lose you guys either, Anna." Elsa gestured for Olaf to hug her as well and the snowman obeyed.
Once they finished hugging, Elsa formed a boat under them so they could slide down the hill.
"Wait, what, what are you doing, Elsa? Hiccup!?" The boat slid back down the hill and towards the forest.
Heather and Hiccup looked shocked as to what happened when his eyes began glowing again and Elsa turned to face them.
"I need to do this alone. And you guys coming with me is too dangerous." Elsa tried to form another boat under Hiccup and Heather, but he melted it and stood his ground.
"Elsa, don't do this. You know you can't stop me." Hiccup was struggling to keep his mind straight.
"Hiccup, I can't risk losing you." Elsa said, firing a blast at him, but he retaliated easily.
Their powers are matched, but are also literally opposites.
"I know you can't. But I can't lose you, Elsa. I love more than anything else and I would risk my own life just to see you live another day." Hiccup dodged all her blasts and retaliated by melting everything she sent his way.
Elsa was about to fire again for Heather, but one of the Sentinel dragons latched onto Hiccup's arms and flew away with him.
"Hiccup!" Heather and Elsa yelled as Elsa reached for Hiccup's hand but missed by a flinch.
"Windshear!" Heather called her dragon and leaped on her back and flew after them with Toothless following.
"Stormfly, kids, go after Anna and make sure she's all right!" Hiccup called back them all. "Liry, stay with Elsa!" He told her and the Light Fury obey as Elsa looked at the retreating shape of her boyfriend and his friend.
-
Anna and Olaf slid through the trees as Stormfly and the Night Lights tried to catch up to them.
"Olaf, help me stop." Anna asked the Snowman while she was trying to grip onto something. "Give me a hand!"
Olaf tapped her on the shoulder and handed her one of his arms.
Anna held the snowman's arm and spotted a branch sticking out over the ice slide. She held the arm up and the hand grasped the branch, sending the boat of the slide and into the river.
"Wait, no, no! Come on!" Anna screamed in frustration as the dragons glided above them.
The boat sailed downstream spinning around as the dragons tried to stop the boat themselves but it isn't working.
"Anna, this might sound crazy...but I'm sensing some rising anger." Olaf told her.
"Ah, well, I am angry Olaf. She promised us we would do this together." Anna shouted at him while pulling twigs out of her hair.
"Yeah, but what I'm sensing is rising anger in me." Olaf explained to her how he's unsure of his emotions.
"Wait, you're angry?" Anna and the dragons looked at him with confusion as they've never heard this snowman in four years ever say he's angry.
"Ah, I think so. Elsa pushed me away too and didn't even say goodbye." Olaf explained and the Night Lights all coo, try cheer their friend up.
"And you have every right to be very, very, mad at her," Anna told him while gripping the side of the boat.
"And you said something never change. But since then, everything's done nothing but change," Olaf admitted to Anna.
"I know. But look, I'm still here holding your hand." Anna held Olaf's hand up and the snowman smiled.
"Ah, yeah that's a good point, Anna." Olaf told her while his hand copied his movements. "I feel better, your such a good liste-"
Before Olaf could finish, Anna covered his mouth and told him to shush.
"Don't shush me, that's rude." Olaf tried to remove her hands, but she turned his head to see why she was shushing him.
"Look." She whispered, turning him to show there are several earth giants lounged out on the river bank.
The dragons tried to stay as quiet as possible as the boat continued to move around the sleeping rock giants.
"Oh. The giants, they're huge," Olaf whispered back to Anna as the Night Lights squeaked at him to be quiet.
The boat suddenly got caught in the air stream of one giant as it lay in the water, Anna and Olaf sat very still trying not to wake him.
Stormfly grabbed the edge of the the boat and pushed around his nose and towards a dead-end.
Anna spotted another channel and paddled towards a cave.
"Hang on, Olaf. Stormfly, your gonna have to go around." Anna told Stormfly as she nodded and flew above the river while the Night Lights stayed on the boat with the two of them.
The boat glided into the tunnel as Anna and Olaf looked back at the giants, she them turned to see a waterfall.
"Try not to scream," Anna told Olaf as she gripped the edge of the boat, Olaf turned to see what she means and held his hand to his mouth.
The boat went over the edge of the waterfall and the occupants held their screams in till the end.
-
The Night Lights burn up a piece of wood to act as a torch for them to see.
"Thanks guys," Anna says and picks up the torch and sees where they're going and found Olaf's nose.
"Where are we?" Olaf asks.
"In a pit with no way out." Anna says as she held up the small branch torch and started looking around.
Olaf called out, pointing at a small hole in the cave wall. "But with a spooky, pitch-black way in."
He quickly went through the hole, the cave opening up into a small tunnel. Olaf quickly took Anna's hand.
"Come on, it'll be fun. Assuming we don't get stuck here forever, no one ever finds up...and you starve and I give up or the baby dragon's eat me. But, bright side, Elsa and Hiccup have gotta be doing a whole lot better than we are."
The Night Lights rolled their eyes at their friend and wondered what did happen to their uncle after he was taken.
