Castle of Wind

This is a world where maybe there is a god. What is the most influential profession in the world? Painter? Musician? Sculptor? Writer? None. You mean magician? Sorry, no magic. Mechanics because they can change the world. He is a machinist because he studied under the greatest machinists. But people don't call him a mechanic because he has traveled all over the continent. This is not a sword and sorcery story because there is no magic. This is not a story of rebellion against gods and demons, because no one has proven that they exist or do not exist. This is just a story about an amazing trip. Follow the wind and travel around the world. In fact, it is a story about traveling with a girl in a "car"...
