To whoever decided to click on this story:

If you are familiar with me or any of my past works, you may remember my most popular story- "Once Upon A Nightmare". I wrote it about two years ago, and it currently has over 40 reviews (the most reviews any of my stories has received), but it once had a totally different storyline than what you may recall.

Once Upon A Nightmare was originally supposed to be a crossover with Ever After High, but because the story I had in mind for that was flawed and had a lot of issues, I scrapped it, and the story's title was given to a completely different fanfiction. The crossover idea seemed utterly hopeless, and I told myself I would never write it.

Here I am, two years later, writing this introduction. I am in the middle of another story at the moment, but I couldn't help but stray from that story to write this one. I am aware that Mattel is/was planning an EAH and MH crossover, but I wanted to give it my own spin. If you are here from the Ever After High Fandom, then I beg that you forgive me if someone acts out of character or if a certain piece of information is missed. Ever After High never really caught my interest as much Monster High did, but I'm trying to learn what I can from these characters.

Thank you for reading, and please enjoy!

Prologue:

In the beginning, there was nothing.

And then, there were people.

The people divided themselves into two social classes: the commoners and the heroes. The heroes had their title because they did things that most commoners were too scared to do- they fought dragons, they defended themselves and their villages from ghastly creatures and enemies of all kinds, and their kisses of true love could break any curse. The commoners looked up to the heroes and loved them dearly, and they wrote down stories about these heroes so they would not be erased from history. The heroes had their own village, and the commoners had theirs. Life seemed to be in perfect balance.

Then, the Great Storm came. It washed away the heroes' village, and it sent them to a completely different reality from the commoners. The heroes were replaced by the monsters, and without the heroes to protect them, the commoners retreated to a separate area. They hoped and prayed that the heroes would return one day, but to no avail.

When an oracle in a temple was asked about whether or not the heroes would come back, he gave this prophecy:

"One day, there will be a portal to the heroes' world, and you will be able to cross over and see them. However, many years into the future, The Great Storm will return and bring the heroes with it. The Monsters, Commoners, and Heroes will all live in harmony, but you must all learn to live together,"

The weeks became months, and the months became years. The years became decades, and the commoners soon lost all hope and wiped the heroes away from their history. Those stories which were once truth were now just stories for children or 'Fairy Tales'. Future generations saw the stories as just that- stories.

Little did the commoners know, centuries later, the oracle would prove to be correct.

Chapter One:

C.A Cupid returned to Monster High through the usual portal, and she had a whole slew of stories to tell her friends.

On Monday morning, she hurried eagerly to her group of friends, and they readily embraced her with open arms. Throughout that morning, Cupid told anyone and everyone who would listen all about the Fairy Tale World and how wonderful everything was. The monsters of Monster High were all amazed by what they heard, but some thought Cupid's stories were, well, fabricated. Toralei Stripe, for example, believed the stories to be fabricated.

"She's full of it," Toralei snorted during lunch that day, as she and the werecat twins watched Cupid talk animatedly about her adventures. "I mean, really- all this talk about Snow White, Sleeping Beauty, and whatever...she's off her rocker,"

"It does sound kind of cool," admitted Purrsephone quietly. "I used to love Fairy Tales,"

Meowlody agreed. "Yeah, come on, Toralei. Do you think we could try her portal?"

Toralei scoffed. "Her portal? Come on, girls. You really believe a word out of her mouth? Anyway, I'm not interested,"

"But, yeah," concluded Cupid as she finished another story. "That's just the way things worked out,"

Frankie tapped her chin with her plastic fork thoughtfully. "I think the whole idea behind their school is kind of, well, sad. You mean they have to follow in their parents' footsteps, no matter what?"

"Yeah," admitted Cupid. "See, there's this idea that if they don't follow their destinies, they die, and their entire universe collapses. I'm not sure how true that is, though,"

Upon hearing this, Jackson considered the idea. "Huh. It may just be a myth. I don't see how their whole world could just stop because of someone not following the footsteps of their parents, but I feel like I would hate that. Can you imagine if we had to do that?" he shuddered at the thought. "I think we should all be grateful that Holt will never become the original Mr. Hyde,"

Cupid chuckled a bit, looking away. "Yes, we should all be very grateful," her eyes wandered across the Creepateria until they landed on one particular vampire: Kieran Valentine.

"What's he doing here?" she asked, rather surprised.

"Oh, Valentine?" Frankie looked too, and she shook her head. "A lot's happened since you've been gone, Cupid. He's reformed now, but he's just become...really awkward, I dunno,"

There was a brief pause as Cupid watched Valentine eat all by himself. "He's alone,"

"Leave him," it was Clawd. "Personally, I still don't trust him. He's probably waiting for the right moment to-"

"Stop it!" Cupid cut him off, and she stood up after a moment. "I'm going to invite him over,"

She turned out the protests from her friends as she walked briskly to the table and placed a hand on the vampire's shoulder. "Hey, Kieran! How are you doing?"

Valentine looked up, rather surprised. "Chariclo! W...what brings you here?"

"I just got back," Cupid sat down, smiling at him. "It's good to see you again,"

When he realized that she bore no grudge, he grinned right back at her. "You too,"

Over at the werecats' table, Meowlody noticed the interaction between the two other monsters. "Uh oh. Don't look now, but it seems Cupid's got a friend,"

"Who?" Toralei looked up, and rage instantly filled her veins. "Oh, hell no!"

Purrsephone rolled her eyes at the reaction. "Come on, Toralei. You guys broke up like a month ago. It's time you got over him already,"

Toralei didn't argue. Instead, she just glared from her spot as Cupid pulled up a chair for Valentine to sit in.

And then- Toralei got a horrible, awful, wicked idea.

"Actually," her facial expression changed, and her voice slowed. "Maybe we should get Cupid to show us that portal,"

Meowlody quirked an eyebrow. "What? Why?"

A grin slowly spread across Toralei's face. "But not her usual portal," she turned to her friends, her eyes agleam with mischief. "She's got to make one. From scratch,"

Towards the end of that same day, Cupid went to the gym to set up some decorations for the big casket-ball game that evening. As she hoisted herself up on a chair to hang some streamers, the werecats approached her.

"Hiya, Cupid!" greeted Toralei in an obnoxiously loud tone, startling poor Cupid terribly. "Could you do my friends and I a little favor?"

Cupid sighed and rolled her eyes. "You must think I'm really stupid,"

Toralei smirked and crossed her arms, amused. "And why is that?"

"Don't you get it?" Cupid climbed down from the chair, gathering some more decorations. "I'm not trusting you wth anything ever again. Not after what happened last time,"

When Cupid stepped back on the chair, Toralei began again. "Look, it's really nothing special. Nothing at all! Just a small favor for my friends and I,"

Cupid considered the request, and she slowly got back down to face the werecats. "What do you need?"

"I need you to take us through a portal," explained Toralei, lifting her chin up. "A portal to your Fairy Tale World. And not your regular portal, a brand new one!"

C.A Cupid took in the information slowly, and she shook her head. "No. No, forget it. No way am I going to make a portal for you and then take you through it. It's too risky,"

"Aw, come on!" protested Meowlody. "You've talked it up so much, we'd love to see it!"

"I might be able to take you there someday," Cupid tried to explain gently. "But it will be through the regular portal that's been around awhile, not a fresh one. Besides, why do you want a homemade portal, anyway?"

Toralei just smiled deviously. "Why, so we can have a direct link from here to the other school. Here's an idea- make it in the Catacombs!"

At this, Cupid picked up the box of decorations and began to walk away. "You've lost your mind, Toralei! I won't be making a portal to anywhere, and it's not going to be in the catacombs!"

Cupid walked maybe ten inches away before Toralei pulled out a slip of paper with a dramatic sigh. "Then you leave me no choice. I suppose I'll have to leave this at Valentine's locker,"

Toralei tried to hide her giddiness as Cupid froze directly in her tracks and turned around. "What is that?"

"Nothing," Toralei batted her eyelashes, trying to look innocent. "Just a little note,"

"Let me see that!" Cupid nearly threw the box on the ground and stalked up Toralei, snatching the note away. It read:

"Party tonight after the casket-ball game in the gym! We'd love it if you could come!

- Clawd"

Cupid's brow furrowed. "Are you serious!? Are you going to stand Valentine up or something?"

"Maybe," Toralei grinned devilishly. "After all, we all know Clawd would never invite Valentine to a party like that,"

"You're disgusting!" snarled Cupid. "I can't believe you would try and play a joke on a poor, lonely manster-"

"Unless," Toralei cut her off, plucking the note from er white hand. "You make that portal for us,"

Cupid fell silent, and she looked away. She tried to think of an alternative, but with those werecats staring her down in such a manner, she felt she had to give in. "Fine! But you have to promise me that Headmistress Bloodgood won't find out. Making a portal from scratch is risky business,"

Toralei just grinned. "Oh, she won't. Just get someone to keep watch! Meet you in the Catacombs in one hour,"

It is unknown if this event was what would trigger the return of The Great Storm, but experts years later would agree that it certainly was a factor.
