caitlyn visits vi in prison

One idea could be a story where Vi and Caitlyn have to team up to solve a mystery in the undercity that's been causing chaos. They start off with their differences but gradually learn to trust and rely on each other more as they dig deeper into the case.

Romance is also a very popular theme. Given their relationship in the Arcane series, fanfiction writers like to explore the romantic aspect between them. This can range from a slow - burning love story to more passionate and intense relationships. Some fanfictions focus on how they overcome their differences and fall in love.

Another theme is justice. Since both are characters associated with law and order in their original setting. Fanfics often explore how they uphold justice in different situations, sometimes even having to make tough choices between what is legal and what is morally right.

A plotline could be that there's a new criminal organization in Piltover that's using advanced technology to commit crimes. Vi and Caitlyn are assigned to take it down. Along the way, they face many challenges and obstacles that test their skills and their relationship. As they get closer to the mastermind behind the organization, they also discover some secrets about the city's power structure that could change everything.

Another theme is the exploration of their different personalities. Caitlyn is often seen as more refined and proper, while Vi is more rough - and - tumble. Fanfics play with how these differences can create both conflict and attraction. For instance, their different approaches to solving problems in Piltover can lead to interesting interactions and storylines.

Fanfiction.net is also a good place. There are many different stories about them there. However, the quality may vary, so you might need to do some sorting. But it's definitely worth checking out.

A great fanfiction idea is one that delves into their relationship dynamics. For example, how they deal with their differences in social status.
