Hi guys! This is the first fanfic that I've written in years, so I might be a little "rusty". Hope you enjoy!

Disclaimer: I do not own the Legend of Korra or Avatar: The Last Airbender

Summary:

After strange creatures from the spirit world begin causing turmoil in the United Republic, Avatar Korra and her friends, Mako and Bolin are mysteriously transported 70 years in the past, during the time of Avatar Aang. They need to find him, since he's their only chance of returning home, but they also need to keep Korra's identity as the Avatar a secret. However, they slowly realize that they were sent to the past for A REASON. The spirits that are destroying the present originated from Aang's time. They've had decades to grow and mature, and now they're killing everything in sight. Can Korra and Aang destroy the spirits once and for all? Or is the United Republic truly doomed?

Note: This also includes romance. I know "Zukorra" sounds odd, but you'll see how it works. I'm also adding "Makorra" too.

ON TO THE STORY!

Book One: Fire (火)

Chapter 1-Blue Lights and Earthquakes

Korra sauntered up the steps that led to Mako and Bolin's apartment, feeling nervous. How would she break the news to them? The brothers had been her best friends since she arrived at Republic City, and she could imagine that they would be crushed. Maybe there was another way. Maybe…

No, stop it, Korra, the young avatar told herself. She had to do what was best for the citizens of the republic. Even if it meant saying goodbye to her friends.

Korra took a deep breath and knocked on the door. Here goes nothing, she thought.

It was Mako who answered. The firebender seemed puzzled and furrowed his brow in confusion. What was Korra doing there at such a late hour?

Korra looked away from his gaze. "Do you mind if I come in? It's kind of important."

Mako cleared his throat. "Uh, sure," he said, opening the door wider. Korra walked past him, entering the living room where Bolin was listening to the radio.

"Hey, Korra!" he said, leaping from the couch. He had his signature grin on his face.

Korra tried, but she couldn't bring herself to smile back. She sadly wrapped her arms around herself. "Hey, Bolin."

Bolin's grin faded. "Something, wrong Korra?" he asked, a little worried.

Korra sighed. "You guys might want to sit down for this."

Bolin looked at his brother, who shrugged in response. He didn't know what was going on either. They plopped down on the sofa, waiting for Korra to speak.

She took a deep breath. Should she just come right out and say it? She was no good at this type of stuff. Korra bit her lip, unsure of what to do.

Mako raised an eyebrow. This wasn't the Korra he knew. She was normally as vicious as her polar bear dog, Naga. What was bothering her?

"Just tell us, Korra. It can't be that bad-"

"I'm leaving Republic City!" she blurted out in a rush, stunning Mako and Bolin. They couldn't have heard her right. There's no way she said she was leaving.

It took Mako a second to find his voice. "W-What?"

Korra buried her face in her hands. "Guys, please don't make this harder than it has to be. I have to do this. I have to go."

"Why?" this time it was Bolin who spoke.

Korra looked up, exasperated. "You already know why! Those spirits are popping up everywhere. People all over the world are dying. I can't just sit by and do nothing!"

For the past few weeks, strange creatures from the spirit world had been terrorizing the United Republic. At first it was just one, but the number had slowly grown to nearly 20. To make matters worse, the creatures appeared to be unstoppable. Even the best benders were murdered by the beasts. Mako expected that Korra would have to fight these things eventually. He just didn't think that it would be so soon.

He opened his mouth to argue, but Korra cut him off. "It's my duty as Avatar to protect the people," she reminded him. "There's no way around that."

"But what about your duty to this city?" Mako countered. He was off the couch now, towering over her. "Amon is still out there. You can't just leave."

"And you can't tell me what to do," Korra said, pointing her finger at his chest. Mako was starting to make her angry.

"What if you get hurt? You're not even a fully realized avatar! It could be dangerous."

Korra turned away from him. "Don't you think I know that?" she scoffed. "Besides, it's not your concern."

There was a pause before Korra felt a hand on her shoulder. "I care about you, Korra," Mako said softly. "So it is my concern." He gently spun her around so they were face to face.

Korra faltered. He cared about her? As a friend or something more? Her head was swimming with possibilities, when Bolin's voice interrupted her thoughts.

"Um, guys…" he pointed to the window. "You should probably take a look at this." They rushed over to see what Bolin was talking about.

Korra's eyes widened in surprise. A blue beam of light illuminated the arrow on Aang's statue, glowing brighter by the second. It was super strange.

"What do you think it means, Bolin?" asked Mako

Bolin turned to answer him, when suddenly the floor beneath them began shaking violently. Tiles from the ceiling fell down as Korra, Mako, and Bolin staggered back in alarm.

Bolin panicked. "It's an Earthquake!" he screamed. He ran for cover, leaving poor Korra and Mako to fend for themselves. Korra stood glued to the floor in uncertainty as everything around her trembled. They didn't get these kinds of things in the South Pole, so she didn't know what to do. She heard a loud cracking noise above her, but before she could process what it was, she found herself being knocked across the room by Mako, just as a large chunk of the ceiling caved in.

"Umph!" her head bumped against the floor. Her vision became cloudy and the world started to spin. And then she seemed to be falling.

"Mako! Bolin!" Korra couldn't see at all. She fell through the air, thrashing wildly. What was happening to her?

A light reached her eyes. She blinked, trying to see something, anything. The world slowly came into focus and Korra realized that she was falling…from the SKY. She landed on the ground with a "thud".

"Ugh," she groaned, rolling over in the grass. She felt like road kill. As she sat up something clicked in her brain. Grass? She thought. There shouldn't be any grass in the apartment!

Korra looked around her. She was in a forest and it was… sunny.

"Huh?"

She heard moans behind her. Mako and Bolin were just waking up too. Wincing, Korra got on her feet and walked toward them. "Do you guys know what happened?" she asked as she helped them up. They seemed dazed and confused.

"Bolin rubbed a sore spot on his head. "Nope, not a clue."

Mako stared into space in deep thought. "I don't get it," he finally said. "There aren't any forests near the arena. How'd we get here?"

He was right. There was something weird going on, and Korra had a bad feeling about the situation. Her instincts told her that earthquakes weren't supposed to transport people to different places.

"We should get back to the city," she said after a few moments of silence. "I think I hear voices coming form that direction." She pointed to her left.

Mako nodded in agreement. This was probably some freak accident caused by nature. He and Bolin followed Korra through the trees, anxious to get back their home in the pro-bending arena.

Mako trudged along, thinking about the flash of blue light that occurred before the earthquake. He wondered if it could have something to do with Avatar Aang. It just didn't seem normal to him.

His thoughts were cut short when Korra came to a sudden stop, looking around in fear.

"Do you hear that?"

"Hear what?" asked Bolin.

"Those chimes. I could've sworn that-"

A specter in the form of an old man whipped past her head, glowing a bright blue. What the hell?! She had to be seeing things. Her hand reached out to touch it, but she only she only felt air.

The spirit smiled at her. "Silence is golden," it said, "But combining it the key to victory."

And then it vanished.

Korra shook her head, completely freaked out. It looked like she had just come into contact with Avatar Roku, the Avatar before Aang. And he seemed to be trying to tell her something? She felt herself being nudged by Bolin, snapping her back to reality.

"Korra? You okay?"

"Um, yeah," she said, quickly composing herself. "I think we're nearly there."

They walked a few more paces before coming to some large bushes. Mako parted the branches, allowing the group to look through.

They definitely weren't in Republic City anymore.

Instead, a village with cobbled stoned streets lay before them. The buildings had large, red sloping roofs with gold trimming. In fact, everything was red, including the clothing that the bustling crowds of people wore.

"Are we in the Fire Nation?" Korra asked in disbelief. How the hell did they get here?

Mako nodded, taken aback himself. "I think so. But why does everything look so old?"

"Yeah," added Bolin. "I feel like I've stepped into a history book."

And then it dawned on them. The light on Aang's head. The Earthquake. And an old fire nation village. The two brothers exchanged a look.

"KORRA!"
