This is a world of steam and magic. The Russian Empire. The provincial town was shocked by the death of a young girl. Someone stole her soul. It's up to Baron Karl Munch and his faithful partner Mikon to find the thief. But the girl’s death is only a link in a chain of terrible crimes. And all the answers are in Venice. Here, at night, castles soar into the sky, chained to the ground with steel chains. Here the magicians of the Venetian lodge of the Sea Hydra weave conspiracies. Here, in the secret laboratories of the Greenhouse, terrible spells are created, and the rebels decided to rewrite the history of the Earth. They are guarded by Sinners who drink other people's magic. Karl Munch and his friends must stop the Faceless Mutiny at any cost or perish under the fragments of the old world.
