Author's Note:

Hi everyone! So this is my first LoL fanfic and I'm going to screw with the timeline a little bit. I'm making Caitlyn and Vi younger, like 19, but they're already working together. Caitlyn is also not the head sheriff yet. I'm not exactly sure where she falls in the chain of command, but she's not the head, yet.

I hope you guys enjoy :).

Chapter 1

It was a mostly normal day in Piltover, which meant that the streets were completely crowded with people. Caitlyn forced her way through the crowded street, trying to catch up to her targets. The two men she was chasing each had a small bag of stolen hextech crystals.

As they reached the edge of town, Caitlyn cursed. It would be extremely annoying if they managed to escape into Zaun.

Then a flash of pink appeared, and one of the men dropped, unconscious. Poor guy's going to get a concussion. The other took one glance at the pink haired woman with giant gauntlets before sprinting down the street as fast as he could. Smart move.

Caitlyn didn't even bother to slow down as she passed her partner. "Take him in. I've got the other one."

"Why do I always get the boring jobs?" complained Vi.

Caitlyn ignored her and continued running after the other man. They were in the boundary markets now, and they were even more crowded than the streets in Piltover, if such a thing was even possible. She couldn't shoot here without risking accidentally hurting a bystander.

The man looked over his shoulder. Caitlyn gave him a cocky smile and his eyes filled with fear. He turned a corner and Caitlyn followed him into the back alleys. Here there were fewer people, but still enough to stare at them in confusion. They turned another corner and suddenly Caitlyn was staring at an empty alley that forked at the end.

She stopped for a second and listened. She could hear loud clomps of boots against cobblestone to her left, so she turned left and continued her chase. It wasn't long before she finally found her target again.

He was running down a long empty alley, save for one child. Caitlyn ran past the little boy and dropped to one knee, aiming her rifle. She pulled the trigger and a beam of energy pierced straight through the man's thigh.

He crashed to the ground and rolled as he pulled out a hextech gun and fired. Caitlyn sidestepped out of the way, but her stomach dropped when she realized that it was now aimed at the little boy, who had stuck around to watch the fight.

Suddenly, another boy dropped from the roof of a building and knocked the little boy away. The newcomer was a teenage boy, probably around 17 or 18 years old, and he had a white mohawk and a white hourglass painted on his face. He was holding a metal sword looking thing, and looked like he just came out of a fight since he was covered in bruises.

"Run," he ordered the younger boy, who only hesitated for a second before running away.

By the time the younger boy had disappeared behind the corner, the older boy was already in front of the thief. The thief didn't even have time to react before the boy brought his sword down on the thief's hand, knocking the gun out of his hand.

The thief screamed as he clutched his hand and started scooting backwards. But he didn't make it very far before an electric net fell on him. Caitlyn lowered her rifle and relaxed, assuming the fight was over. But apparently the boy didn't think so.

He chucked something in her direction and she sidestepped it on instinct. It flew past her and hit something else. She didn't know how to describe it. It looked like a man fused with a machine. Green tubes were sticking out of his back and pipes connected it to a mask over his face. His arms had been replaced with mechanized fists and there seemed to be several other pieces of his body that were augmented. He must have been trying to sneak up on them.

The thing the boy through suddenly exploded, sending both the augmented man and her flying backwards. Caitlyn fell down slightly dazed and watched as the device flew back towards the boy.

The augmented man snapped out of his daze and charged at the boy, passing right by Caitlyn. Caitlyn felt her eyebrow twitch. Did he not consider her a threat?

Caitlyn propped her rifle up and quickly changed the setting. The augmented man and the boy were currently duking it out, but the boy managed to evade each of his opponent's moves with stunning speed.

Caitlyn waited for the perfect opportunity before firing. One of the augmented man's giant fists just got incinerated. It wasn't long before the boy disabled his other arm. Caitlyn flipped a switch and fired another electric net.

The augmented man dropped next to the thief, completely incapacitated, and Caitlyn started walking towards them.

"That's what you get for underestimating me," she said with a cocky grin.

The augmented man just glared at her as she approached even closer. Then a body slammed into hers and they were both sent flying backwards. She opened her eyes to find the other boy on top of her.

Caitlyn was about to push him off, but then an explosion erupted where the two men were. Caitlyn's eyes widened when she turned her head to find two charred corpses.

"Run!" yelled the boy as he pushed her to her feet.

Another explosion was all the encouragement she needed as the first one set off a chain reaction. When did they even have time to set that up?

As she ran, her foot suddenly fell into a pothole and she hissed in pain as her ankle twisted. Her body crashed onto the floor, but the other boy didn't even break his pace as he grabbed her arm and pulled it over his shoulder.

They managed to hobble out of the alley, well, it was mostly him dragging her out. One last explosion sent them both crashing into the ground. Caitlyn waited for another explosion to sound, but after a long period of silence, she decided that it was over.

Caitlyn pushed herself up and tried to put weight on her foot, but hissed in pain.

"Look's like your ankle's sprained," said the boy.

"No shit, Sherlock," replied Caitlyn.

He looked at her, slightly shoked. "You have quite a bad mouth for a Piltie."

"And you have quite a chivalrous attitude for a Zaunite."

The boy visibly bristled. "Not all Zaunites are mad evil scientists."

"Not all Pilties are pompous stuck-ups."

"... point taken."

Caitlyn could feel a smile tugging on her lips. Normally she wouldn't dare utter such words, but it wasn't like any of the higher ups were here and this was Zaun, so it shouldn't matter that much.

The boy suddenly grabbed her arm and pulled her up. He positioned her arm around his neck. "Come on. I'll help you to the Howler."

Caitlyn could feel her face redden. "I can get there on my own."

"Sure you can, Top Hat."

Caitlyn tried to place weight on her injured ankle again, but hissed out in pain.

"Told you."

Caitlyn sighed and leaned most of her weight against the boy. The boy grinned and she just glared at him as they started walking.

"So what's your name?" asked the boy.

"Isn't it customary to introduce yourself first?"

The boy rolled his eyes, "so you are a rule loving Piltie."

"And apparently you do have the mouth of a Zaunite."

The boy snorted. "And you have one that would put the majority of Zaunites to shame."

"...was that a compliment?"

"That depends of your viewpoint."

"Then I'll take it as a compliment."

The boy laughed and Caitlyn could feel herself smile as well. A moment of silence passed before she spoke again.

"It's Caitlyn."

"I'm Ekko, but you can call me his majesty the awesome."

"Okay, Mr. stuck up Zaunite."

"Shut up, Miss bad mouthed Piltie."

Caitlyn grinned just as the elevator connecting Piltover and Zaun came into view. Then she heard someone yell her name.

"Caitlyn!"

Both Caitlyn and Ekko turned to find Vi jogging up to them.

Caitlyn could feel Ekko stiffen. Vi also stopped when she noticed Ekko. Caitlyn looked between them. Did they know each other?

"Oh. Hey, Ekko," said Vi.

"Hey," said Ekko emotionlessly. He removed Caitlyn's arm from his neck and Caitlyn shifted her weight so it fell on her good foot.

Ekko turned around. "I'll be going now," he said as he started walking away.

"Erm. Thanks!" said Caitlyn at his retreating back.

Ekko didn't respond as he disappeared in the Zaunite crowd.
