Chapter I - Frozen Heart (Prologue)

"There's beauty and there's danger here… Beware the frozen heart."

(3rd Person POV)

A long way off there is a kingdom called Arendelle, where two young brothers live. Both princes to the kingdom. The two couldn't be any closer. But on one fateful night, everything changed.

"Levi! Wake up. Wake up. Wake up!" Eren whispered, getting up on to the raven haired boy's bed and sitting on top of him, jumping and pushing him lightly.

"Eren, go back to sleep." Levi mumbled sleepily.

"I just can't." Eren replied, flipping over and laying on top of a sleepy Levi. "The sky's awake, so I'm awake." He added rather dramatically, putting his arm on his forehead for added effect. "So we have to play." He threw his arms to the sides.

"Go play by yourself." Levi grumbled, shoving Eren off him and onto the floor.

Eren landed with an "Oof". He sat and pouted for a moment before coming up with a new idea. He excitedly climbed back on top of Levi and opened one of Levi's eyes. "Do you wanna build a snowman?" He asked, knowing he had gotten Levi's attention now, smirking. Levi opened his eyes and smirked back.

The two ran down the stairs hand in hand, the shorter brunette chanting "Come on, come on, come on!" as Levi shushed him to be quieter so they wouldn't wake their parents.

They ran into the large empty room and shut the door, giggling as they went. As they ran to the middle of the large room, Eren spoke excitedly, "Do the magic! Do the magic!"

He waited excitedly as Levi moved his hands, creating a small ball of snow that glowed with magic. "Ready?" Levi asked, holding the ball. Eren nodded excitedly, gazing intently at the magic in Levi's hands, his sea green eyes shimmering. Levi suddenly threw the ball up in the air; the ball leaving a glowing trail of snowflakes behind it as it traveled up before hitting the ceiling and bursting into a million beautiful glowing blue snowflakes.

"This is amazing!" Eren yelled, throwing his hands in the air and jumping around as the snowflakes fell down around them.

As Eren ran around the room, giggling excitedly, Levi leaned over to speak to him. "Watch this!" He announced excitedly. He moved his foot and planted it in front of him. The floor began to glow with ice as it covered the entire room, giving the entire room an even more beautiful blue hue to it. Eren laughed as they both started to slide on the now slippery floor.

As the snowflakes continued to fall down, the room was soon covered completely with snow. The two began rolling large balls of snow. Levi finished the largest as Eren brought over the one to put on top.

As they finished the snowman, Levi put the nose on as the final touch and Eren sat and squished his face together impatiently as he waited to see the finished product of their creation. Levi finished and turned the snowman around, standing behind it and moving its stick arms as he spoke for it. "Hi, I'm Armin, and I like warm hugs."

Eren clapped his hands excitedly before jumping up and running over to the snowman; Armin. "I love you, Armin!" He hugged Armin while smiling over to Levi, who smiled right back.

Eren spun around with Armin as Levi pushed them, using his powers to move them along on the slick ice, both giggling happily. "Armin," Eren exclaimed excitedly as they went along.

Levi and Eren slid down a slide made of snow, Eren in front and throwing his hands in the air excitedly. "Tickle bumps," he giggled as they slid along and over the bumps of snow. As they went onto the last bump, Eren went up with an "Oh," flying into the air and landing in a large pile of snow. He came out of the pile throwing snow and laughing, before standing up and jumping.

"Hang on!" Levi exclaimed, creating small hills for Eren to land on as he jumped.

"Catch me!" Eren yelled enthusiastically, continuing his jumping.

"Gotcha!" Levi answered excitedly, creating more hills as Eren jumped.

"Again!" Eren announced, jumping again.

"Wait!" Levi called worriedly, trying to keep up as Eren continued to jump higher and faster, giggling while doing so.

Eren jumped again with a loud "Whoo-hoo!" as Levi yelled for him to slow down. Levi suddenly slipped and fell on the slippery ice as Eren continued to jump, not paying attention to Levi. He jumped again with a loud "Whoo!" this time jumping off the last and largest one.

"Eren!" Levi yelled, throwing an arm out and sending a blast of magic at Eren accidentally, hitting him in the face. Eren grunts at the impact as he falls, landing in another pile of snow and rolling down the hill, unconscious, a white stripe now in his hair. Levi gasps and gets up, running over to Eren and kneeling beside him. "Eren!" He cradles an unconscious Eren in his hands as his breathing quickens in worry. "Mother! Father!" He cries out desperately, on the verge of tears. He curls into Eren, sobbing as he whispers "No, no…". Hard ice soon begins to frost over the floor, quickly spreading over the floor and up the walls, covering everything in sight.

"You're okay, Eren. I got you." Levi cries gently to him. There is a loud banging on the door to the room as their parents try to open it through the ice. Once they open the doors they both gasp.

"Levi, what have you done?" Their father gasps, both parents run over to the two children. "This is getting out of hand."

"It was an accident. I'm sorry, Eren!" Levi speaks quietly.

Their mother grabs Eren and picks him up, gasping. "He's ice cold."

"I know where we have to go." Their father says, looking to Eren in his wife's arms. She looks over to him, surprised.

Their father searches for a book before finding the one he is looking for, opening it and finding a map.

The parents, along with Levi and an unconscious Eren, go on horseback to the place the map has led to.

They ride through the forest quickly, a blue frost in their trail. They pass by a small girl with brown hair and glasses with their reindeer as they go.

"Ice?" The girl exclaims, watching them rush past. Soon the girl and reindeer are following the trail. "Faster, Sawney," she calls, riding the young reindeer; Sawney, through the trail of ice.

They stop and hide behind a few rocks at the end of the trail, watching quietly as the scene unfolds before them.

"Please! Help! It's my son." The father yells out, hoping for an answer. Soon, thousands of rocks roll around them, surrounding them. The girl gasps from her hiding place at the sight. The family huddles together as they are surrounded.

The rocks begin to transform, thousands of small trolls appearing in their place. "It's the king," one whispers as they all murmur quietly.

"Trolls?" The girl gasps from their hiding place. Suddenly the rock beneath them transforms into a troll also.

"Shush!" The troll shushed her. "I'm trying to listen." It added, yanking the two back down to crouch. Sawney licked the troll's cheek. "Cuties. I'm going to keep you." The troll exclaimed, squishing their faces gently.

"Your Majesty." The troll talking to the family bowed quickly before going to Levi and taking his hand. "Born with the powers, or cursed?" He asked.

"Born. And they're getting stronger." Their father; the king, stammered.

The troll moved on to Eren next, beckoning the queen to kneel down so he could see Eren better. "Here, here." He spoke quietly, resting his hand on Eren's forehead. "You are lucky it wasn't his heart. The heart is not so easily changed. But the head can be persuaded." He shrugged.

"Do what you must," the king replied worriedly.

"I recommend we remove all magic." The troll begins, moving his hand to Eren's head again before moving his arm with a trail of magic, creating pictures showing the memories of Eren and Levi playing together with Levi's powers. "Even memories of magic, to be safe." The memories switch through, the sceneries changing within the memories as they go. "But don't worry. I'll leave the fun." The memories swirl into a ball in his hands before he moves it over Eren's head, resting his hand there and sighing. "He will be okay." He moves away.

"But he won't remember I have powers?" Levi asks, looking over to Eren.

"It's for the best." Their father assures.

"Listen to me, Levi. Your power will only grow." The troll speaks to Levi, walking and showing figures of Levi in the future in the sky. "There is beauty in it…" The figure in the sky creates a beautiful giant snowflake in the sky. "But also great danger." The snowflake burst red. Levi gasps. "You must learn to control it. Fear will be your enemy." The figure is surrounded by people, once astounded and now angry. The people pounce on the figure and the picture is gone. Levi gasps and runs to his father. His father holds him close.

"No!" The king announces. "We'll protect him." He assures his wife. "He can learn to control it. I'm sure." He tells the troll.

"Until then… We'll lock the gates." The castle's gates close. "We'll reduce the staff. We will limit his contact with people," The staff begin to close the windows and doors in the palace and Levi's room is soon moved out of the shared one with Eren and into his own. "and keep his powers hidden from everyone. Including Eren." Eren watches as Levi goes into his own room, closing the door behind him sadly.

Eren gasps sadly as he watches the door close.
