Piltover is a thriving, progressive city whose power and influence is on the rise. It is Valoran’s cultural center, where art, craftsmanship, trade and innovation walk hand in hand. Its power comes not through military might, but the engines of commerce and forward thinking. Situated on the cliffs above the district of Zaun and overlooking the ocean, fleets of ships pass through its titanic sea-gates, bringing goods from all over the world. The wealth this generates has given rise to an unprecedented boom in the city’s growth. Piltover has - and still is - reinventing itself as a city where fortunes can be made and dreams can be lived. Burgeoning merchant clans fund development in the most incredible endeavors: grand artistic follies, esoteric hextech research, and architectural monuments to their power. With ever more inventors delving into the emergent lore of hextech, Piltover has become a lodestone for the most skilled craftsmen the world over.
Zaunites and Piltovans alike flock to the Bridgewaltz market for a taste of everything that makes the undercity great. The best in music, food, and artisanal chemtech creations can be found here every night.
Travel between Zaun and Piltover usually entails a long and tiring climb, but towering elevators exist that allow for swifter transit.
The wealthiest in Zaun maintain isolated crystal-houses known as cultivairs that contain trees and plants as a symbol of their power and a source of clean air.
The Gray is a by-product of the proliferation of chemtech industry throughout Zaun. It is believed to be the cause of the lung blights that afflict many Zaunites.
Zaun is a large, undercity district, lying in the deep canyons and valleys threading Piltover. What light reaches below is filtered through fumes leaking from the tangles of corroded pipework and reflected from the stained glass of its industrial architecture. Zaun and Piltover were once united, but are now separate, yet symbiotic societies. Though it exists in perpetual smogged twilight, Zaun thrives, its people vibrant and its culture rich. Piltover’s wealth has allowed Zaun to develop in tandem; a dark mirror of the city above. Many of the goods coming to Piltover find their way into Zaun’s black markets, and hextech inventors who find the restrictions placed upon them in the city above too restrictive often find their dangerous researches welcomed in Zaun. Unfettered development of volatile technologies and reckless industry has rendered whole swathes of Zaun polluted and dangerous. Streams of toxic runoff stagnate in the city’s lower reaches, but even here people find a way to exist and prosper.
