Bang Ho-young, a struggling young man, suddenly finds himself transmigrated into his favorite grind-heavy game. Branded a nuisance by the Queen, he is exiled to the frontier as the “Baron of the Borderlands.” What he receives as his domain is nothing but a barren wasteland—ruins overrun by endless waves of monsters. With no soldiers, no resources, and no allies, his only hope lies in his unique skill: [Pacify], the power to tame and convert monsters into loyal comrades. From goblins to wyverns, every creature he tames becomes a new shield for his land. With wit, grit, and his growing monster army, Ho-young begins building a thriving stronghold where ruin once stood. The frontier’s last defense has begun—led by a lord who commands both men and monsters.
