The young knight of Karhad Vale, Baron Carlisle, returns from the war, but at home, in the very heart of his homeland, he discovers a new enemy against whom honest steel is powerless. Now he is forced to enter the fight for everything that is dear to him, fighting according to alien rules with alien weapons, because the legendary drow assassin, who entered the service of the king, prefers treacherous intrigues and deadly poisons to a noble fight, and his motives are unknown. Meanwhile, a new, hitherto unprecedented threat looms over the world of Sangaria, coming from outside (fantasy, demons, drow, etc.)
