Author's Note: This is just a short multi-chaptered story to introduce my OC. I intend for the genre to remain as friendship.

With that said, the ending is pretty open-ended as I am fairly satisfied with leaving it as it is. However, I am open to ideas. If anyone wants me to continue or very kindly suggests plot ideas, I'll see what I can do.

As for my fandom qualifications, I have not read the books, but I have seen the movie twice.

Since I am horrendous at descriptions, I'll leave the 7 Sins and the other spirits to your imagination.

Disclaimer: I do not own Rise of the Guardians.

Chapter 1: Present - 1

Jack lets out a strangled cry of pain as a sharp heel digs deeper into his spine.

He is lying on his front, his body pinned to the snowy ground with one hand stretching out to the side towards his staff, straining to reach it –

"Ah ah ah! Not so fast, Jackie boy!"

The foot presses harder into his back as its owner bends down to sweep his staff away. Twirling it smoothly in her hands, Pride smirks down at the trapped Guardian as he struggles to free himself.

"Look at you!" she crows in delight. "Reduced to a pathetic little mortal without your little stick!"

"What do you want?" Jack half growls, half groans in pain as he twists his head back as far as he can to glare at her.

"Oh, nothing much really," she replies lightly. "Just to see who the new Guardian that old man living on the rock in the sky picked this time. Imagine my surprise when it turns out to be Jack Frost! The lonely little snow boy who has only the Wind to play with." Pride leans towards him and whispers in his ear. "Tell me Jack, doesn't it just make you sad? Knowing that you wield so much power, yet no one believes in you?"

"Ha!" Jack barks triumphantly. "Lady, maybe you've been living under a rock the whole time, but in case you didn't know about how we Guardians defeated the Bogeyman several months ago, more and more children are believing in me every day," he grins as Pride's face twists into an ugly snarl. "And it's not like you're any better. No one really knows who you are, everybody just lumps you together with the rest of your pack!"

Pride's eyes flash with outrage as she tosses Jack's staff to the side towards Sloth, who is standing nearby watching the two with bored disinterest. He barely catches it and fumbles slightly, not expecting his fellow Sin to leave the winter spirit's conduit with him.

"How dare you!" she hisses, reaching down to grab the back of his neck in a choke hold. Jack yelps as he is suddenly lifted off the ground, dangling at the hands of the taller Sin. "I am more powerful than the rest of my siblings! How dare you belittle me!"

Jack struggles furiously as he grabs at the bony hands on his neck, digging nails into the tender skin. "Let me go!" he demands.

"As you wish," Pride smirks evilly. "The ice and cold are your domain, your pride and power. Let's see what happens when I take that away, shall we?"

With her other free hand, the Sin makes a waving gesture that summons a glowing circular ring of fire around them. The flames quickly melt the snow on the ground inside the ring, turning it into warm water as it seeps into the barren earth within seconds. At the snap of her fingers, the flames shoot up towards the sky and collapse inwards, forming a blazing dome of fire trapping them both in. Jack gasps breathlessly at the abrupt spike in temperature and dryness, and grunts in pain as he is abruptly released and promptly dropped onto the ground.

"It was nice meeting you Jack," Pride casually waves at him before stepping over his panting body to pass through the dome to the other side, unscathed. "Don't worry, I'll pass on your regards to the other Guardians and let them know why you won't be joining them today."

She turns to Sloth, still holding Jack's staff. "Get rid of that," she orders. "Break it or burn it, I don't care. Just make sure he can't get to it." And with that, she disappears into the snowstorm.

Sloth looks at the staff in his hands and then at the winter spirit inside the dome, watching his crumpled form crawl weakly towards him before collapsing in a heap, breathing and sweating heavily. The Sin looks at the staff again before shrugging his shoulders lazily and dropping it onto the ground, just a few feet outside Jack's prison.

With a satisfied nod, he hurries after his sister.

A pair of bright green eyes peers out from behind a snow bank, blinking a few times after the other Sin has departed. Cautiously, a reindeer rises from its hiding position, looking left and right to check for other hidden spirits. Assured that no one else is around, it slowly approaches the dome of fire.

Bracing itself, the reindeer forces its way through, grunting slightly in pain as the raging flames singe its coat of fur. As soon as it gets in, it carefully gathers the unconscious winter spirit with its antlers and gently deposits him onto its back. Taking a deep breath, it makes a quick and forceful charge out of the dome, pulling its head back to shield Jack with its antlers as it breaks through the wall of fire and out into the snowstorm.

Stumbling as it gathers its bearings, the reindeer shifts to make sure Jack won't fall off. After securing his position and ensuring he's as comfortable as possible, it picks up his staff in its mouth, turns towards Santoff Claussen, and begins the long trek back.
