A guy in a hood with an artificial tech eye walks through a world where people (and vampires and mutants and other vermin) fight each other with grenade launchers and magic. Where the Czech landscape has been badly damaged by centuries of war and creatures that came to us from the Other Side. The savior is searching for his soul and the truth about his past, aided by Margareth's shotgun, Grayson's grenade launcher, and the giant Demon Slayer revolver. He makes his living exclusively as a mercenary hunter and sells goods he finds in abandoned villages. His life takes an unexpected turn when he learns that decades ago, he himself led an army of demons against humans in the greatest battle of our time—the Battle of Sevastopol. Can this be true?
