They created a thriving metropolis built on steam power and machinery. They became the envy the world as they automated all their work, and lived lives of luxury among their robotic servants.
Freed from their labor, the citizens created wonders. They built a massive clocktower that became the symbol of the age. You could hear it from every corner of the city.
All those engines required power, and they built robots to dig into the earth, to pull coal from the earth and fell the forests for firewood.
When the waters rose, the clock still tolled in the abandoned city.
