The novices from the Epiphany Monastery are respectfully called Masters of the Unclean by the people—for their skills and selfless courage in standing up to otherworldly forces. Brother Arsentiy, in the past a prince’s squadron commander, is one of those masters. Sometimes alone, sometimes with other brothers, he fights against vampires, werewolves, and sorcerers, risking his life and sparing no one. Arsentiy isn’t a wizard, he’s an ordinary man—so against the unclean he uses only weapons in capable hands, ancient knowledge, and desperate bravery.
