The Frontier Lord Begins with Zero Subjects

After spending decades at war, Dias finally returns home as a hero. The king rewards his service with a domain of his own, but the promised territory is nothing more than an empty grassland without houses, farms, or a single resident. Dias knows how to survive a battlefield, not how to govern land or build a settlement from nothing, and for the first time he has no orders to follow. His situation changes when Alna, a mysterious girl with a blue horn, appears on the plains and reveals that the frontier is not as lifeless as it seems. Their meeting draws new companions to Dias and gives him the chance to create a home through patience, practical work, and the same determination that once carried him through war.
