Ashes of dead stars

A world where magic and technology have always developed side by side. The dwarf cybernetics here are adjacent to the biotechnologies of Yaern, the witchcraft and the spell of spirits - with power fields and machines to control physical constants. Interstellar empires are constantly inventing something new. The galaxy is full of miracles, and life is not enough to see them all.
But not every miracle for the good. A drug that enhances telepathic abilities. A device that can extinguish the stars. The sect, whose affairs go beyond the understanding of scientists and theurgs ... The fragile balance is kept only on the intricacies of diplomatic agreements and political intrigues, and when a new, unknown player comes into business, everything sets in motion. Someone set out to change the world - but will he be able to cope with the avalanche he called?
