Luka, a boy who lost everything when his hometown was burned to ashes, longs to join their ranks. Yet during the Ritual of the Pact, he is suddenly attacked by a monster and driven to the brink of death—without being able to offer anything in return. In that desperate moment, what awakens within him is the sealed, forbidden flame. Will this pact and its flame become the Knights’ beacon of hope, or will it herald a new calamity? Thus begins a dark and unrelenting battle fantasy, where the forbidden fire blazes to life!
