The next day everyone reached the Black Mountains. Kristoff had pulled the sled over seeing that there was no more snow in the mountains to go on. They had to walk the rest of the way. Elsa was walking a bit slower than everyone else. Rapunzel stopped to look over her shoulder and saw that Elsa was falling behind.

"Guys, we should slow down. Elsa is getting tired again." Rapunzel tried to tell the boys.

Elsa's head shot up. "No, no. Keep going. I'm fine. Really. We have to get to Grand Pabbie remember?"

Jack walk up to Elsa. "At least let me give you a piggy-back ride."

Elsa blushed picturing how ridiculous that would look. "Jack, that's very kind but don't you think that would look a bit foolish?"

Jack looked at her thinking that she was acting odd. "Elsa. It's not like we have any subjects to impress here. It's just us."

Elsa sighed. "Good point I suppose." She climbed on his back and they kept moving along the rock-lined pass. Elsa was always so amazed how he could always end up making her feel a little bit better when she needed it. Soon she fell asleep on his back.

They finally made it and the saw the swarm of rocks.

Kristoff called out for them to wake up. "Hey guys, we came to visit!" which wasn't really true but he didn't want to shock them all if he got straight to the point. "Grand Pabbie? Bulda?"

Suddenly they saw the rocks start to roll toward them and then everyone revealed themselves to the group.

Bulda was the first to speak. "Kristoff and the whole family! It's so great to see you all! Come, come, everyone." She grabbed Kristoff's hands and pulled him towards the other trolls as she motioned for the others to follow. As Rapunzel was following along with the rest of them she saw some of them stare at her hair looking amazed by how long it was. Especially the youngest trolls who were feeling it as it went by them. Bulda saw this. "Children, it's rude to stare." The little trolls that were touching it and staring backed away from her hair.

Rapunzel sat down with the rest of them. "It's alright, Bulda. What I'm really shocked about is how you recognize me without my brown hair?"

"Oh, who could forget your pretty face?" Bulda smiled. Rapunzel smiled back, glad that she didn't have to explain anything. Bulda then looked to Elsa who looked a bit flushed and tired. "Elsa dear, you look exhausted and a bit different. Are you alright?"

Elsa ignored the question and quickly changed the subject. "Look. Not that I'm not glad to see you all again but I really need to speak to Grand Pabbie. Where is he?"

Bulda looked at her with concern and knew that she was keeping something to herself but she decided to not ask questions. "Yes. He's here somewhere. I'll go find him." As Bulda walked away Elsa felt relief. She wasn't sure how much longer she could keep the baby a secret. It was really hard to do.

Jack looked at Elsa from the corner of his eye. She did seem to look a bit sick during this journey every now and then. He had a feeling that something was up. Maybe she just ended up making herself sick by worrying so much about Anna. He held her hand trying to calm her. "Don't worry, we'll save her."

Elsa smiled at him. Inside she felt terrible. Not just because she literally felt sick but also because she knew in her heart that Jack deserved the truth.

Shortly Bulda and Grand Pabbie appeared.

"Grand Pabbie." Elsa said when she saw him coming.

"I sense great distress your family." Grand Pabbie said to everyone. He looked at the group of the worried royal family but then saw the problem when he didn't see Anna. "Has something happened to your sister?"

"Yes. She has suddenly gained powers much like me. I fear that if she continues to possess these powers things could go completely wrong like I did once in the past. She claims that she can control her powers but somehow her powers have changed Rapunzel's hair to the way it once was years ago and she's alone in Arendelle right now. Please tell me there is a way to reverse all that's been done." She begged.

"There is a way." Grand Pabbie then looked to everyone again. "I need to speak with Elsa in private please." Everyone looked a bit disappointed but nodded. "Thank you." He pulled Elsa gently by the hand away from the group.

Grand Pabbie took Elsa through a forest. Behind them waterfalls cascaded down in the silvery light from the northern lights in the sky. They came to a stop at a mirror of water. There was no other way across but to swim through. Elsa saw Grand Pabbie go through it but then came out completely dry to motion Elsa to follow. They went on through slicing into the mirror of wet-less water.

Elsa found that she could breathe through the water and they swam above a luminous garden of waving shapes.

They then came to the other side of the water and walked into a stand of willows. In there long faintly glowing purple tendrils hung straight down in pastel curtains

Underfoot, a bed of moss glowed faintly. It reacted to their footsteps with expanding rings of light.

Elsa barely kept track on following Grand Pabbie. The place was such and exquisitely beautiful spot.

The willows stirred, responding to their presence. Grand Pabbie held up his hands, letting the tendrils caress him. Elsa did so as well.

"Elsa." Grand Pabbie started. Elsa stopped admiring the area and quickly gave her attention to him.

"Yes?" she said back sounding anxious.

"You are the first human to ever come here."

"Why?" Elsa asked with curiosity.

"You are special. Only those who have been born with powers can breathe through the mirror of water. That's why only you could come talk to me in private."

"But what about Jack? He has powers."

"Yes, but without his staff he doesn't truly have powers of ice like you. Also even if he were here then we wouldn't be able to discuss something that you have been keeping a secret from everyone except for Rapunzel."

Elsa gasped, "You know? How?"

"I know many things, especially if it involves another family member that's to come. Elsa, you mustn't worry yourself too much about your sister. If you do your child could be in great peril and might disappear."

Elsa looked down in shame. "I've been questioning myself many times about this. Is it wrong of me to keep the baby a secret from everyone?"

Grand Pabbie sighed. "It is your choice. I cannot decide something this big for you."

She nodded. Then she put out her hands and the tendrils played over his fingers, her palms, and her forearms. Her eyes went wide when she turned to see a beautiful tree with crystals growing from its branches. She walked up to it and Grand Pabbie came after.

"What is this tree?" she asked.

"We call this the Tree of Pure Crystals. These crystals have not been turned into element crystals yet."

"Element crystals?" Elsa repeated in question.

"Element crystals are crystals that were once pure crystals that grew on this tree. We use them to have it around our necks when we need them. For us to earn our element crystals we have to withstand and become one with the element we are trying to obtain." He gently picked off a pure crystal from the tree. "For example: to gain a Fire Crystal we have to stay in a cavern with fire all around you for one whole day. It's intensely hot and dangerous but eventually every troll must do it if they want the power. Without powers that they are born with, humans wouldn't be able to do the test. They would die. Trolls are more immune." He then turned back to Elsa. "You on the other hand, could live though these hardships because you where born with your powers. You can even get a element crystal without having to do the element's test."

He gave Elsa the pure crystal he had taken off the tree. She accepted it gently from his hand. But as soon as she touched the crystal it started to turn a glowing white colour.

"What did I just do to it?" she asked a bit startled.

"Because you have ice powers already. You turned it into an Ice Crystal. It is now an element crystal." He answered. "It is yours now."

"It's beautiful and thank you but what does this have to do with saving Anna?" she wondered as she put the Ice Crystal around her neck.

Grand Pabbie then had a dead serious look on his face. "Well, pure crystals are not only used for what I have just told you. They can also take powers away from people who have gained powers without taking the test. Us trolls believe it is the tree's way of letting us know that getting an element without taking a test is unforgivable and unfair." He paused for a few seconds and took another pure crystal from the tree and gave it to Elsa. Then he spoke again. "If you're sure you want to do this you must touch Anna with this pure crystal. Once it touches her it will drain her of her newfound powers."

Elsa grasped the crystal tightly. She thought back about how happy Anna had been about getting powers of her very own and felt a bit guilty but Elsa didn't want to risk Anna's safety.

"Thank you, Grand Pabbie. I owe you much." she thanked him.

Later they came back to the group and the other trolls. As soon as they all saw the two coming they ran up to them.

Kristoff was first to speak. "So?"

Grand Pabbie raised his hand to Kristoff to cease him from asking too many questions. "All of you don't have much time. You must hurry."

Elsa lightly put her hand on Kristoff's shoulder. "Don't worry. I'll explain on the way."

Kristoff nodded. As they all said goodbye to the trolls and set on their way Grand Pabbie whispered to Elsa. "Remember. Stay calm for your child."

"I will." She said. Then she went to catch up with the rest.

A/N:God damn I hate using my imagination this hard. It was hard having to come up with an explanation for the crystals that the trolls wore in the movie. I hope you can understand they way I said they worked and I hope you don't think it's a dumb idea on how they work.
