Royal Butler Corps

When the forbidden *Song of Incantation* grimoire is stolen from the Black Moon Order, dark magic erupts across the continent—summoning beasts, twisted bio-constructs, and monstrous aberrations that defy all conventional weapons. Humanity's last hope lies in the Royal Executor Corps, an elite legion of contract mages who wield the very summoning arts that unleashed the chaos. Led by Archibald, a former bishop turned mercenary commander, these monster hunters stand between civilization and annihilation. In a world where magic and science collide, only the strongest summoners survive.
