Summary
Silence swallowed the room, and the sudden dread of everything filled their chests.
Pieces of the invention sprawled across the floor, wires splayed like broken limbs, fragments of months of work glinting under the moonlight. No one moved. No one spoke. The laughter from minutes ago felt impossibly distant, leaving only the shock of what had happened.
Caitlyn and Mel moved to check if Jayce was alright. Viktor walked over to the sheet covering the invention and pulled it off. He was the only one brave enough to look at the damage. Caitlyn, Mel, and Jayce looked at each other, avoiding what Viktor had revealed.
-------------------------------------------------------------------------------------------------------------
Vi was left with a bitter first impression of Caitlyn and her friends and wants nothing to do with them. But they aren't willing to let their paths end there. Between brutal bot fights, unexpected opportunities, and a mystery pulling them together, they will have to trust one another or risk losing more than each other. -

Summary
“Are you happy, Cait?”
Who knew such a simple question could be so loaded? Caitlyn Kiramman sure didn't. She thought she was happy. She had the seemingly perfect life. Good job, stable family, more money than any one person had any right to have, a fiancée who loved her. Everything was coming up Kiramman, as far as the universe was concerned. But was this really it? Was this what happiness truly was?
Was this as good as it gets?
~~~~
Vi was pretty sure this was as good as it was going to get for her. Fresh out of prison, with a roof over her head, a good job, a best friend that hadn't abandoned her, and her sister...she finally had her sister back in her life again. Her life felt good for the first time in a long time. Not perfect, because perfect was a fantasy, at least for Zaunites like her. They didn't get perfect, not like the Pilties did. But for Vi, this had to be as good as it gets.
Right?

Summary
In which Caitlyn retreats to a small island to heal, discovers that peace comes in many strange forms, and gets smitten by a local fisherwoman.
Or
Caitlyn moves to Sudaro expecting quiet, distance, and time to put herself back together. Instead, she finds an island full of wild animals, excellent cupcakes, questionable local politics, and Vi: a fisherman who somehow holds the entire village together while pretending she absolutely does not care. As Caitlyn settles into island life, she realizes healing doesn’t always look like solitude. Sometimes it looks like shared meals, shell hunting and learning to stay.

Summary
“Violet Lanes ?” Caitlyn chuckled, thinking it was some kind of joke. “Like the famous boxer ?”
Vi wandered over to the expensive vintage sofa and flopped down onto it. “Yep. Exactly. Like the famous boxer.”
Caitlyn blinked into the silence as it hit her that Vi was actually serious. Her face flushed so red she thought she might faint. How many times had she watched Violet’s fights a few years ago with the biggest crush on her and those muscles ?
———
Caitlyn finds out her new fling is a fraud when she comes face-to-face with the woman’s wife, Vi. They team up to confront their lying lover but find their hearts beating a bit too strongly for one another to be just friendly solidarity over a vendetta.
After all, what could be gayer than falling for your wife’s mistress ?

Summary
Caitlyn Kiramman was a lot of things. She was the Councillor’s daughter, born into a life of privilege and luxury. She was an A star student, leaving education with a degree and immediately starting her career as a detective. She was head of detective’s, the person that her co-workers looked up to. And most importantly she was Vi’s girlfriend, and had been for several years. They’d met in high school and were practically high school sweethearts. Caitlyn knew everything about Vi, and Vi knew almost everything about Caitlyn.
Caitlyn was a neutral. Or that’s what she told everyone anyway.
or
Ever since Caitlyn Kiramman was classified as a little five years ago, she’s hated it. She’s been overtaking regression blocker pills since she was classified, but now moving in with Vi, she can no longer access them.
A classification AU.

Summary
“My name is Caitlyn Kiramman,” she said, “and I am the Sheriff of the Piltover Police Force.”
“We need your firsthand knowledge of the scenes, the conditions, and even the equipment involved. My team and I are here to listen, collaborate, and investigate — together.”
Vi heard the remaining muttering die down, and she knew Sheriff Kiramman had succeeded in putting them at ease.
Despite herself, Vi scowled. Fires were their domain, and their previous experiences with the police didn’t exactly make her optimistic about this round.
Still, there was something about the sheriff that made it hard to look away. Whatever it was, Vi hated that it made her want to listen.
OR
Caitlyn's a detective; Vi a firefighter. Amidst a spate of serial arson cases exploding across the city, the two are thrown together to investigate and collaborate, unearthing decades-old cold cases and a love neither of them knew existed.
This is what happens when conspiracy, corruption and crime is woven into a blossoming, slow-burning love…

Ghostface!Vi and Detective!Caitlyn modern AU
“Is that why you’ve called?” Caitlyn asked them. “To tell me who you are?”
“Is that what you want, Detective Kiramman?” Ghostface asked her, feeding on the curiosity and obsession of this case. And Caitlyn took the bait easily. The way they said Caitlyn’s title made the back of her neck tingle.
“Yes. It is.” Caitlyn answered honestly.
“I can show you.”
----
A string of killings had set Piltover City on edge. Unknown intentions by and an unknown killer. Detective Caitlyn Kiramman had been at every crime scene. She'd seen the gruesome deaths the victims had encountered. The polaroid pictures left at the scenes that the killer themselves had taken. The only description they have is a tall, muscular figure dressed in all black and wearing a mask, which had earned them the name Ghostface. A name that has been haunting Caitlyn for weeks. Who is Ghostface? Why are they killing? And why are they leaving gifts on Caitlyn's doorstep?

Summary
“What are you doing?” the woman asked, breath catching.
“Still being bold,” Vi said, her grin returning as her fingers closed around the woman’s hand. “And hoping you’ll remember tonight… in case it is just a passing moment and I don’t ever see you again.”
The woman opened her mouth, but no words came. Vi noticed the parts of her features not obstructed from the mask looked softer.
Vi leaned in slightly, close, but not yet touching. “Unless you don’t want to see each other again.”
The woman’s fingers flexed gently against Vi’s, holding her stare.
“I wouldn’t dream of that,” she said softly.
OR-
Vi and Cait meet at a masquerade, never learning each other's identities. But what happens when they meet again without the masks? Familiar details making them wonder, but them both convincing themselves it can’t be true.

Summary
Jinx looked Caitlyn up and down, now realizing why the women were suddenly all over the undercover detective. “You bitch,”
Caitlyn’s attention snapped up, frowning, “I know.” Her irritated tone had more of an edge to it by the second. The alpha’s fidgety behavior and sour attitude was beginning to make more sense.
Jinx drummed her fingers on the countertop, “You’re on the job and you’re in rut?!” she hissed under her breath.
Caitlyn sighed loudly, “Not. Yet.”

Summary
She leans in, voice a whisper. “You flirting with me, officer?”
“What?” Caitlyn looks up, blinks, not entirely sure if they heard that correctly. Jinx can’t help but blush at the confused look.
“Do you want to check the CCTV, officer?”
Caitlyn frowns ever so slightly, but it's noticeable. “No, it's okay, I’ll send one of the uniforms to come collect it.”
“If you remember anything relevant,” they say, sliding a card across the counter, “call me.”
Jinx picks it up, smiling. “Giving me your number already? You move fast.”
“That’s not—” The detective sighs. “Please. Only if it’s relevant.”

Summary
Rookie detective Caitlyn Kiramman thought she understood the rules—follow the trail, uncover the truth, serve the law. But when a string of high-profile murders shakes the city's elite, each marked by a cryptic calling card riddle, the lines between right and wrong blur fast. Caitlyn manages to solve the puzzle and reach a victim before the killer strikes again. And for one brief moment, she believes she succeeds—only to find a woman already standing over the corpse.
Vi, a volatile enigma with a rap sheet to match, flees the scene. But later that night, she’s waiting in Caitlyn’s apartment—not to finish the job, but to ask for help. Vi claims she knows who the real murderer is… and that she’s not trying to stop them out of mercy, but revenge.
The killer is connected to a deeper conspiracy, one that cost Vi her family. And the only way to find them is to work together—if Caitlyn can figure out whether Vi is an ally, a liar… or something far more dangerous.

Summary
“What the hell is that?” Vi broke out.
Caitlyn did not respond.
“I mean that clearly wasn’t there before, right?”
“No. No, it wasn’t.” Caitlyn uttered, before finally getting ahold of herself.
She immediately grabbed her rifle. Expertly loaded it and supported the barrel on the inner shoulder of the driver seat. She looked through the scope, her finger twitching to turn off the safety switch.
After a couple of torturous moments Vi finally blurted out.
“What is it, Cait? What do you see?”“I don’t know, the fog, I can’t-“ Caitlyn anxiously stammered. “I cannot tell but judging from its size I fear it’s likely a person.”
Vi let that info sink in. There it was again, that ugly weight clawing at her shoulders. She couldn’t dwell on it again, fuck that.
OR
The exclusion zone expands in a desperate attempt to contain and conceal the outbreak of a violent epidemic. Having barely escaped as the city fell into anarchy, Caitlyn and Vi now struggle to survive and link up with what is left of their families, as well as their own humanity.
