The war in the polis is flaring up more and more. A wave of sap from the plane of death has reaped a terrible harvest. But the clans of sorcerers, as if not noticing this, are still settling scores with each other, pretenders to the Princely throne appear like mushrooms after rain, and strangers who want to profit during the turmoil are crawling out of all the cracks. But the Bazhovs and their young Prince do not intend to retreat. For too long, the green-eyed clan has been divided. Now the time has come to get together and show how the owners of green fire can fight. And the news is very opportune that the legendary Ignis has been found, a gift to the clan from the Mistress of the Copper Mountain herself. Just what she will demand for such generosity, and what kind of monster lurks in the depths of the catacombs under the polis, Anton Bazhov has yet to find out all this. It’s not for nothing that he is called the Prince of Green-Eyed Beasts.
