Hello people of FF! I am basically a newbie here who happened to write her first fan fiction ever! This is actually to test my skills and passion for writing and to express my fluffy love for the Team Jelsa! (I've only been a Jelsa shipper since last Friday, isn't that swell?) Anyway, I hope you like this fan fiction, and I'm not expecting a wide readership since it's my first try at doing this. But anyhow, please do enjoy!

Disclaimer: I do not own characters of Rise of the Guardians nor Frozen. They belong to DreamWorks and Disney. But if I did own them, then this would never have been called a fan fiction.

Summary

It's been a year since the Guardians' last encounter against Pitch Black. Jack is commended for his exemplary job on his first year in bringing frosty fun to the children of the world. But then when the winter season comes, the moon turns red and a horrible blizzard of black snow threatens to cover Burgess. Cold and fear ensues, and Jack Frost suspects that it is the work of the boogey man yet again. With the Man on the Moon rumored to be in danger, the guardians look to Father Time to trace the whereabouts and when-abouts of the snow chaos. That's when Jack Frost and the gang land themselves back in time, in the castle of Arendelle, where a queen dressed in ice sings to her sister about her ideal man. (Jelsa, of course.) First fic ever!

Prologue: A Bloody Anniversary

My name is Jack Frost, and I am a guardian.

It's been a year since I took my oath, and believe me; things were pretty cool now that I'm having more people believe in me since Jamie. A day from now would mark my first anniversary as one of the guardians of childhood, and according to jolly old North, we'd be celebrating back at his place. Though I've been here to the North Pole many times, the place never ceases to amaze me. Every year, millions of toys are put together by yetis (contrary to popular belief that elves do the work) to bring to every child on Christmas. I still remember the times when I tried breaking in to this place… ah, those good old days with Phil!

Having new friends took a little time getting used to, and one of the perks of being a new guardian is that you get to meet more than the Tooth Fairy, the Easter Bunny or the Sandman. Based on Sandy's… uhm, sand pictures, we'd be having guardians from the different departments. Apparently we weren't the only guardians out there after all.

"I still dunno how Manny does it." North told me. "'' Tis pretty excitin' since fellas like Cupid would be coming to meet you!"

I raised my brows. Huh, so there was a guardian for Valentines' Day too. "You don't say."

"Mother Nature is coming! Ooh! Ooh! And the Fairy Godmother! Both of them got really beautiful teeth!" Tooth twittered happily as some four or five fairies swooned behind her. I rolled my eyes. Typical of Tooth.

"I still believe this whole celebration is a waste of time… when I should be back at the Warren painting me more Easter eggs!" Bunnymund complained under his breath, although he still continued setting banners with my name on it. I grinned.

"He just jealous 'cause his first anniversary celebration was a complete disaster!" North whispered to me in his guttery Russian accent.

"Why what happened?" I chuckled, imagining Bunny's face when it happened.

"Do not even go there mate, I just might ruin Christmas." Bunnymund threatened North. He heard us apparently, even though he's a couple of meters away (well, he does have big ears). North let out his signature baritone "Ho, ho, ho" (which by the way sounded nothing like 'Ho, ho, ho.'), winking at Sandy as he formed images of an egg-shaped cake exploding at Bunny's face.

"Wow, I wish I was there to see it, kangaroo." I laughed. Bunny continued muttering under his breath.

"I am a bunny you…" He muttered. I couldn't hear the last part.

"Oh guys I wish I could help you with the preparations but there's so much work to do and-" Tooth paused and started shouting coordinates to some mini fairies. She turned back to us mouthing "Sorry."

"Nah, no biggie." I shrugged, smiling with assurance. I couldn't blame her duty's a 24/7 kind of job. Tooth began to speed flutter away while the rest of the yetis set up decorations. With all the fuss that was going on in North's headquarters, you'd think it was already Christmas Eve.

"North, are you really sure we'll be doing the celebration here? I mean come on, I didn't even know this anniversary stuff is a thing." I smiled at him while secretly stealing a cookie from a tray the elves were carrying.

"That's how we congratulate our rookies for a job well done lad!" North grinned, patting me on the back a bit too hard. "And I thought fun was your center!"

I coughed, "Uh, well, thanks I guess. Sure it won't bother with the toy-making though? Christmas is fast approaching."

"That's why I made the yetis work overtime last January!" North laughed in amusement, but the yetis thought otherwise.

Well, I can't say I'm complaining 'cause I think it's pretty rad what these guys are doing for me. I gazed up at the high window of North's work shop, silently thanking the Man on the Moon for all that he's brought me through. My first year as a guardian really was the best year of my life for the last 300 years.

"North! Look! Something's happening to the globe!"

I snapped my head at where Bunnymund was pointing at. There at the globe where the lights of the children that believed in us flickered began losing its lights at rapid speed. North rushed but I merely stood my ground. It wasn't because I was shocked though I really was, but because something more terrible has caught my attention.

When I looked back at the moon, it was the color of blood red.
