I have read other RotG/Frozen crossovers so I thought I would give it a try. The ended seems a little lame to me but it's all I could come up with...so yeah, here it is. I'm also working on another chapter for this 'fic' and will have it up once I'm satisfied it's complete. It's about a character from RotG that no one has ever really written about and I felt like she deserves to have a chapter all her own even if she only made two/ three appearances in the movie.

Jack, after having learned of a kingdom that was separated from the rest of the world, raced along the wind in search of this kingdom. As he reached the top of the mountain that separated the kingdom he noticed a young woman traipsing through the snow by herself.

He was about to land near her when she started singing and created snowflakes with simple waves of her hands. As a mortal woman showed that she had power over his season, Jack's mouth fell open but his shock turned into joy as he was no longer alone and had someone to talk to about what he, now they, could do.

Jack continued to watch her as she made her way further up the mountain using her powers as she went. The thing that awed him more then anything was the castle she made completely out of ice. He stepped into it and flitted around it, taking in all he could before he had the wind carry him to the top of the ice castle to where the young woman was.

As soon as his feet touched the floor, his presence was felt by the other occupant of the room he took in. "Who's there?" The young woman demanded, slight fear in her voice. In answer Jack tapped his staff lightly on the floor and the words 'I'm Jack Frost, Spirit of Winter' appeared between them.

"Spirit of Winter, what do you want with me?" She took a step back.

'I heard of the hidden kingdom in this area and decided to see what it's like. What's your name?' The young woman read before she gathered up her courage and answered.

"I'm Elsa, Queen of Arendelle or at least I was until I lost control of my powers but now I don't want to go back. How come I can't see or hear you?"

'You have to believe in me to see and hear me.' Elsa closed her eyes and took a deep breath before she opened them. She let out a gasp as a tenn with pure white hair, blue eyes and the most unusual clothes appeared before her.

Jack smirked as she gasped, "Hello there Elsa, it's good to be seen by another who has winter powers. I couldn't help but hear your song as you made your way to where we stand, does the cold really not bother you?"

Elsa took note of the fact that Jack wore no shoes and acted like he wasn't standing on an ice floor. "It doesn't, I take it it doesn't bother you either." She pointed at his bare feet.

"Not since I was reborn three hundred and some years ago from the same pond I drowned in..."

Before Jack could say more Elsa broke in, "Wait- you drowned?" She stared at him, horrified at the thought of someone his age drowning.

Jack shrugged and replied, "Well yeah, I wasn't about to let my little sister drown. I had to save her, I'm sure you know how that is."

"Yes, sadly I do. I had accidently struck her with my power once when we were children and have been scared of using them since... at least until now."

Not knowing what to say, Jack remained silent for a few seconds until he came up with an idea. "How would you like to truly become one with the wind and sky?" He suggested.

"What, do you mean to tell me that you can fly?"

"Well, yeah. So what do you say, would you like to join me?" Jack smirked as he held out his hand to her as he lifted off the floor a few inches. Elsa hesitated for only a second before she placed her hand in Jack's and, with a laugh, Jack jumped into a passing air current, pulling Elsa with him.

At first Elsa was a little scared and she clung tightly to Jack but, once she got used to it, she let her fear go and enjoyed herself. "I never knew...it's amazing, the sight is beautiful. Thanks for this Spirit of Winter."

"Please, just call me Jack and you're welcome miss Snow Queen." He teased.

"Alright then you may call me Elsa, Jack." She laughed as they flew past a figure truding through the snow but the two of them paid who-ever it was no mind. Once they were back at the ice castle Elsa thanked Jack , once more, for showing her what it was like to fly.

With the promise he'll return, Jack left to spread winter where needed, neither knowing what was about to happen, when Jack returned he found that Elsa no longer feared her powers and the two of them, plus Anna, Elsa's younger sister, and Olaf had many fun days playing in the snow.
