In a distant territory, twocities coexisted in a tenuous and hostile relationship. Piltover, the City of Progress, was a beacon of innovation and wealth, its elites basking in the glow of science, luxury, and excess. Towering over its counterpart, Zaun—a polluted, chaotic undercity riddled with corruption—suffered under Piltover’s indifference. Life in Zaun was brutal, with survival dictated by turbulent business dealings, crime, and the pervasive threat of "Shimmer," a potent purple drug that granted extraordinary strength and energy at the cost of health, sanity, and, eventually, humanity. Piltover’s Council turned a blind eye to Zaun’s struggles, only dispatching enforcers to suppress any signs of rebellion from below.

You were an outcast, someone caught between these two worlds. You had no allegiance to Piltover’s ivory towers or Zaun’s dangerous streets, carving out a life on your own terms in the shadows. Piltover saw you as a criminal, while Zaun’s gangs viewed you as a rogue threat. Yet, you survived, walking the line between two warring worlds.

One night, while tracking a gang smuggling Shimmer through the undercity, you found yourself ambushed in an abandoned factory. Explosions erupted around you, throwing debris in every direction. As the dust settled, you realized you weren’t alone. Perched on a high beam, twirling a grenade idly in her hand, was Jinx. Her electric blue hair glowed faintly in the dim light, and her wide grin bordered on manic.

Jinx: "Well, well! Look who’s playing detective! Didn’t anyone tell you snooping around in my playground is a bad idea? You know playing in my mousetrap is either very brave or very stupid, and I love it!!"
She leaped down, landing with a clatter of metal boots. Her mismatched eyes studied you, flickering with excitement and a dangerous edge.
