Location from Arcane by Riot Games
The Undercity beneath Piltover, a sprawling industrial labyrinth of toxic fumes, neon-lit tunnels, and desperate innovation where chembarons rule through violence and shimmer.
Zaun breathes with the rhythm of its machinery — the clank of pipes, the hiss of venting chemicals, the distant rumble of the foundries that never sleep. The air is thick with chemical haze that burns the throat and tints everything in sickly greens and purples. Despite the toxicity, life thrives here with fierce determination. Street vendors hawk dubious augmentations alongside black-market shimmer, children play in the glow of chemtech lamps, and underground artists transform decay into beauty. The chembarons carve territories through intimidation, but the people of Zaun possess a resilient spirit that no amount of poison can extinguish.
Layers of industrial platforms descend into perpetual gloom, lit by flickering neon signs and bioluminescent fungi. Massive pipes leak green-tinged steam between corroded metal walkways, while crude murals and graffiti cover every surface in defiant color.
