02 · The City

The last clean city in the sky

Copper towers, gear-driven bridges and clock faces, held aloft by the Amber Heart, a giant living crystal that powers every engine in Cogspire.

Below the clouds, the Soot Armada rises to rip the Heart out and burn it in their furnaces.

09 · Style Guide

Copper, brass and amber

Round and friendly for the city, heavy and spiky for the Armada. Warm amber means powered and friendly; red-orange furnace glow means enemy. Thick soot-black outlines on characters and towers.
