Explore Piltover and Zaun, create Hextech technology, or unleash a chemical revolution.
The city is on the brink of change.
On the surface, Piltover shines with its technological advancements, grand academies, and the promise of a future built on Hextech. Below it, Zaun survives in smoke-filled alleys, clandestine laboratories, and people willing to do anything to change their fate.
Tensions between both cities have never been higher. Old wounds remain open, and the balance could shatter at any moment.
Whose side will you take when the future of both cities rests in your hands?
