From publisher blurb:
The year is 1894. A mathematically and technologically advanced city was to become the new Utopia of the rational age, but a catastrophe changed everything – the city fell into Limbo, the threshold of Hell. Scientific progress faced ancient magic. The city and It’s people became trapped in a mystical realm that doesn't see sunlight.
The familiar world doesn't exist anymore. Limbo is governed by other laws, inhabited by other creatures – but the scientific method works in the most insane conditions as well. People lit their Steam Sun here. Every morning it rises above the City on a huge rail. Authorities conduct diplomatic negotiations with demons, inventors are crazy about creation of an intelligent automaton, explorers search for traces of ancient civilizations. Scientists, traders, officials, adventurers, cheaters, magicians, policemen, criminal clans, evil geniuses and brilliant detectives, human and demons. All manner of beings can be found in the City of the Steam Sun. Who will you become?
