This world is similar to ours, only there is ether in it. Ether is the fabric of the universe, and under normal conditions it is not much different from our emptiness, but if the ether becomes “hot”, then it can be controlled. This is similar to magic, but with its own laws and restrictions, and the ether also has limits, and everyone has their own limit from birth. There are ethereal stars in this world, they are the ones who heat the ether to a state... But the story is not about that, Oleg is an ordinary guy working at the Moscow observatory. And Oleg... However, this is already a spoiler, and in the book there will be an emperor and his shadow sister and allies, who will change their owners in different ways. Ether is not magic, you should not flirt with it, as the price may be deformity of your body or loss of human appearance.
