Novices from the Epiphany Monastery are popularly respectfully called Masters of Evil Spirits for the skills and dedication with which they resist otherworldly forces. Brother Arsenty, a former prince's warrior, is one of these masters. Sometimes alone, sometimes with other brothers, he fights with ghouls, werewolves and sorcerers, not sparing his life. Arsenty is not a wizard, but an ordinary person, so against evil spirits he uses only weapons in skillful hands, ancient knowledge and desperate courage.
