So, I've started something new. Something really new. This is a Sailor Moon/Once Upon a Time crossover (as the category clearly states). This has been rolling around my head for a little bit and I decided to just sit down and get started on it. This is the prologue. It's short. But be prepared for more pretty soon.

For those Sailor Moon fans: This takes place after the StarS season. But…everyone dies and doesn't come back. So, obviously this is AU. Usagi and the cats are the only two left of our favorite group of super heroes. Not happy with that? Just wait…

Once fans: This is going to be set after Emma and Snow come back from FTL. Regina stopped Cora from coming through the well. But did she really stop her? Just wait…

For fans of one and not the other. Don't worry, you won't be confused for long. I promise. This isn't a usual crossover where everything is explained right away. Just stick with it a little. Everything will come to light soon. Just wait…

So, a lot of waiting is involved. I'm sorry. But I have a plan for this. And I hope people like it! My beta, Laura, was very interested. So, now for the next test…how you y'all like it?

I don't own Sailor Moon (even if I have her tattooed on my skin now) or Once Upon a Time (even though I'll be cosplaying as Emma in September).

Thanks to Laura and all the wonderful people who reviewed the last chapter of "What the World Needs Now". All of you…all of you rock!

Now, without further ado…

It didn't appear to be a special day. It had started like so many others since she started her trip. She woke up in a hotel room, packed her cats and luggage into the car and continued driving across the country. In fact, the day seemed almost boring. The only big event she could see over the horizon was the fact that she had just crossed into Maine, meaning she had reached the end of her trip.

She didn't know what she was going to do once she reached the edge of Maine and the edge of the country. She had taken the trip to just get away. Away from memories and the sadness and horror that came from those memories. But so far, after weeks and weeks of being away from home, the memories hadn't left her.

Tsukino Usagi had left Japan on a whim. Even after 5 years, the deaths of her friends and lover still haunted her. And she figured America would help her escape those past haunts.

But the sadness still hovered over her every night as she stared at ceiling after ceiling of different hotel rooms. The nightmares clung to her, as if in a desperate attempt to remind her of her failings, not only as a friend but also as a hero.

And these were the thoughts as she drove through Maine. The car was silent, not even a sound coming from the radio. All that could be heard was the even breathing of the sleeping cats in the passenger seat and Usagi's harsh breathing as memories assaulted her once again.

"Usagi, can't you remember to try to leave on time one day?"

"Gomen, Rei-chan! I couldn't find my purse!"

"Whatever, Odango Atama! You need to get your head together!"

"Rei! You're so mean!"

A car passing her rental car broke her out of her thoughts. She shook her head and went back to focusing on the road.

"Maybe I should have invited Naru-chan to come with me," Usagi muttered. "At least then I wouldn't be so alone."

One of the cats stretched in her sleep, causing Usagi to give a small smile. She wasn't really alone. But cats, even her special cats, did tend to sleep a lot.

The feeling was sudden. It caught her completely off guard and caused her to slam on brakes in the middle of the road. Thankfully, no one was behind her so an accident didn't occur. But the cats were tossed out of the seat and into the floor.

Usagi's blue eyes were wide, her breath fast, and her brow dappled in sweat. "Kami," she muttered. "What the hell was that?"

It had been like running through a glass wall; a glass wall of magic. It had slammed into her with enough force to make her powers flare up. Her skin felt sensitive to the touch and her lungs burned, as if she had just run a marathon.

"Did you guys feel that?" she asked her cats, who were blinking up at her with glazed, confused looks in their large eyes.

Usagi shook her head and took a deep breath. "That was weird." She blinked and swallowed before slowly closing her eyes and trying to focus on the magic itself.

It wasn't hard to find again. After running through the wall of it, all she had to do was just reach for it. It was still there, not as obvious as before but definitely there. And it was pulsing. Something was happening nearby that involved a lot of magic. And this magic wasn't pure, like hers. It was evil. Tainted. Dark.

Her eyes opened and then narrowed. It seemed that someone was in need of some help. And while it may have been a few months since her last bout with magic, she was actually kind of excited to get back into. It didn't feel like the magic at home but it was there. And if an innocent was in need of help, then the champion of love and justice was going to be there.

"Guys, it looks like we've reached our destination," she said with a slight grin.

The black cat jumped back into the seat and narrowed her eyes. And then, spoke.

"Nani, Usagi? What do you mean?"

The grin widened. "You didn't feel that burst of magic, Luna?"

The cat shook her head and watched as her partner, who looked almost identical to her but with nice white fur, climbed up beside her. "Artemis insisted on hunting until the break of dawn this morning."

"Hey!" the white cat exclaimed. "There were so many mice, I wanted to try to catch as many as possible!"

Usagi giggled and pulled onto the road again, following her gut towards the magic.

"So, what magic are you talking about, Usagi?" Artemis asked, carefully starting to bath his head in an attempt to wake himself up a little more. The gold crescent moon on his forehead caught a bit of sunlight and seemed to blink a little up at the blonde driving the car.

"It felt…weird," Usagi muttered. "Kind of like Chaos but not so evil. Something's going on."

"You sound like Rei," Luna said softly, her crescent moon also catching a bit of light.

Usagi gave a sad smile. "And that's fitting since her powers combined with mine and everyone else's when they died. It definitely comes in handy."

"So," Artemis stated after clearing his throat. "Where to?"

Usagi gave herself a mental shake to break out of the quick depression that had settled over her. That was for the nighttime. Not now.

"We are going to find this magic. I have a slight tug in my gut that someone or even a group of someones is going to need my help soon." She glanced over at the cats again. "You guys up for it?"

"When aren't we?" Luna asked with a smug grin. "I think after 7 years with us, Usagi, you know that we would follow you to the moon."

Loud laughter filled the car as it crossed over an orange line across the road and passed a sign that welcomed people to Storybrooke.
