The wagon sped up north, following the voice's calls. Whenever Elsa heard the voice, she gunned the wagon in that direction. Finally, they reached their destination: A wall of mist. Elsa shook the reins, signalling the reindeer to stop. "The voice was drawing me here?" Elsa wondered. Suddenly, she heard a loud sound and her ears perked up. She looked around for the source and was almost tempted to hop on the wagon and turn away from the mist. Mimicking the voice's calls, she got no response. Yep, this was where they needed to be. The sound sounded again, so Elsa walked behind the wagon and found Anna curled into a fetal position. "Oh, Anna," she said, trying to hide her smile. Anna had fallen asleep, which was understandable considering they spent several days on the road, which was only extended because they had to stop several times, for breaks and to sleep. Elsa climbed into the wagon and walked to her sleeping sister. "Anna? Anna", she said, shaking her. "You gotta wake up", she said. Anna roused herself.
"There already?" she asked as she rubbed her eyes. Elsa nodded as Anna hopped off the wagon. Soon, the sisters found themselves staring down at the mist. Elsa felt Anna's hand grasp her own. She gave her sister a reassuring glance as they advanced forward. Elsa extended her hand forward to touch the mist and to her surprise, it parted. The sisters, with Anna pulling the wagon, entered into the forest as the mist closed shut, surprising the sisters. "What happened?" Elsa asked.
"We're trapped! That's what happened!" Anna shouted. Elsa's brow furrowed.
"So, now what? Why direct me here if it was going to trap us inside?" Anna thought for a minute.
"Let's keep going. You wouldn't be pulled here without a good reason. The question is what?" she pondered, more to herself than anything. The sisters kept walking forward when suddenly, they felt a breeze. Anna tugged her vest. "Hey, Elsa! Does it feel a bit breezer than usual?" she asked. Elsa held a hand out.
"It is! And by the looks of that tornado, it's gonna get worse. Anna, grab onto me and don't you dare let go!" Anna obeyed, grabbing onto Elsa's waist with one hand and keeping the wagon in the other. The tornado swept them up. "All right, Mr. Tornado! Do your worst!" Elsa said as she fired her magic at it. Suddenly, something happened. When Elsa's magic hit the tornado, it formed into sculptures depicting what happened to their father.
"Elsa, look! Mama wasn't a mail-order bride, she was from here! She saved Papa when he was injured and lost consciousness!" Anna exclaimed. Elsa was shocked.
"I don't believe this. Why? Why didn't they tell us?" she asked. They were so absorbed in the sculptures that they didn't realize Elsa's magic had an effect on the tornado, and it was starting to calm down enough to drop them gently on the ground. "Let's keep going," Elsa said and started to walk forward, Anna followed with the wagon. They hiked a couple more miles with Anna began to feel uneasy. She tapped Elsa on the shoulder.
"Elsa?" Elsa stopped.
"What is it, Anna?"
"I'm hungry", Anna said. Elsa pondered.
"Well, I guess we can have a food break," she said. Anna ran to the wagon and grabbed some of the food they brought with them. They ate their fill and continued onward, ultimately coming into a clearing. They heard rustling. "Anna, get behind me but ready your powers in case of a threat!" Elsa ordered. Anna generated a fireball and got behind her sister. Elsa generated her own powers as well when the source of the rustling appeared. It was a person. Anna was about to concede when the person was joined by other people, aiming their weapons at them. She nudged Elsa.
"Is that them?" Elsa looked at her, uncertain.
"Who?"
"Remember Papa's story? The Northuldra?" Anna asked. Elsa scanned their outfits and nodded. Suddenly, the person stepped forward, revealing she was the leader.
"Who are you?" she asked. Anna was dumbfounded.
"Uh, who are you?" she asked, only to receive a spear jab.
"We ask the questions here! Who are you?!" Anna looked at Elsa. They didn't have time to answer because suddenly, they were joined by another group, this time a group of soldiers.
"EVERYBODY! WEAPONS DOWN!" the leader of the soldiers announced. Anna recognized the leader immediately, having seen his portrait in the study.
"Mattias? You're supposed to be dead!" she exclaimed. Mattias and his men advanced on Anna, who threw the fireball at them, stunning both parties.
"You have magic?" he asked. Anna nodded.
"I guess you could say, I'm Anna," she said as she generated another fireball and launched it at the forest floor. "Fire Princess of Arendelle", she finished. Mattias and his men were impressed. They turned to Elsa.
"And you are?" They asked. Elsa smiled and generated her own powers.
"I'm Elsa", she said as she subdued Anna's flame. "Snow Queen of Arendelle," she finished. Both sisters stood back to back, respective powers generating. "We are the Magical Sisters of the kingdom of Arendelle," they finished together. It was a routine they liked to do for the kids of Arendelle once Anna fully accepted her powers. Mattias ordered his men to stand down and bow to Elsa and Anna.
"Effective immediately, we are under your command. Speaking of which, how is little Agnarr?" he asked. Anna's lip quivered.
"You, how can I explain this? Have been trapped for 34 years. Papa's dead," she said. Mattias' face fell. Then the leader stepped forward with one question.
"Why would nature reward two people from Arendelle magic?" Mattias spoke up.
"Probably to make up for what YOU did that got us trapped here, Yelena!" he said in an accusing tone.
"We would NEVER attack first! How dare you suggest such a thing! You may trust them, but I don't! My allegiance lies with nature and the spirits", the leader, Yelena, said, highly offended. Suddenly, Anna felt woozy. She grabbed her head. Elsa grabbed her.
"Anna! Are you okay?" she asked before she turned to the groups. "WHO DID THIS? WHO HURT MY SISTER?!" she screamed. Naturally, the groups were confused. Anna tugged on Elsa's hair.
"Fire!" she said. Elsa looked up and saw a ring of fire approaching. Everyone else backed away, except Anna, who was advancing toward it.
"Anna, no! It's too dangerous! Let me handle it!", Elsa said. Deaf to her sister's pleas, Anna kept advancing towards it. She held out her hand and touched the flame, revealing the source of the fire: A cute little salamander. Anna fell in love immediately.
"Oh! You are so adorable! Yes you are!" she cooed, as she held out her hand. The salamander scampered into Anna's palm as she cradled it. It licked Anna's face, accepting her as its mistress. She giggled as she walked the salamander over to Elsa, in case what she did wasn't enough. "He really likes you, Anna," Elsa said. Anna grinned.
"And I like him as well, he is just so cute and fluffy!" she swooned as she petted him. Turning her attention back to her new pet, she said, "I'll call you Bruni. You like that?" The salamander responded by licking Anna's face again, accepting his name. Suddenly, a young man shouted, "I can see the sky!" Everyone looked up and saw he was right. The mist had been weakening since Elsa tamed the wind and when Anna tamed the fire, the mist had pulled back enough for everyone to see the sky again. Just then, Yelena approached the sisters.
"Excuse me, but how far are you two intending to travel?" she asked. The sisters looked at each other, then Anna explained everything that had happened, from Elsa's dreams to finding out about the prophecy. Everyone was surprised. "Also, apparently, our mother, the queen, was from here," Anna added. Just then, Mattias stepped forward.
"I heard you say you were from Arendelle?" he said and when Anna and Elsa both nodded, he continued. "That's where my men and I are from. Tell me Princess Anna, is Halima still single?" he asked with interest. Anna nodded. Her and Elsa then noticed Yelena and the tribe doing some kind of weird tribal dance and suddenly, they heard Yelena shout, "Tonight, we feast in honor of Queen Elsa and Princess Anna, honorary Northuldra!" To Anna and Elsa, she said. "You are always welcome among us if and when we get set free. The spirits are so pleased with what you've accomplished so far, the curse is weakening, but alas, we still can't leave", she said. This puzzled the sisters.
"What do you mean, weaking?" Anna asked. Yelena smiled.
"All will be revealed. Come," she beckoned.
AN: I'm going off of the idea that for every spirit tamed, the curse placed on the Enchanted Forest would weaken. It seemed like from what I could gather just based on plot summaries: Once Elsa accepted her powers, then she would hear the voice and find her true role (this is what somebody also posted on the Fridge Brilliance section on TV Tropes, which fulfilled the producer's claim that "When you view the first movie in light of what we revealed in the second film, a lot of the story decisions we chose in the first film would suddenly make sense in-verse": The reason why Elsa started hearing the voice in three years was because she needed time to fully accept her powers and repair her relationship with Anna, so that when Elsa found her true role, their sisterly bond would outlast the separation, because Elsa would naturally want to leave a role she wasn't met for and a place she wasn't met to live in). Here, Elsa already accepted her powers, thus she started hearing the voice earlier and that had an effect on the curse conditions. She just never answered it until now and per my bible, she started hearing the voice after their parents died. R&R!
