Welcome to Steam City, the warmest place on the planet! There are two levels to a city on this frozen planet, the one above and the one below. The above part is like any other city. There are buildings, churches, stores and streets. Below are catacombs of pipes channeling water and melted snow to large boilers heated by the planet’s magma layer. Steam is created and used to power and heat the city. Pressure is relieved via big black vent towers, or in Steam City to also activate the musical pipes within the clock tower.
