In Perry's world, mechanics mend and fighters destroy—two immutable laws he learned on Earth. Transported into the body of a young noble brimming with arcane potential, Perry faces an impossible crossroads: brave the Front's deadly expanse where Hydras and Devils hunt, or forge an entirely different path. He chose the oath. A binding vow that transformed him into a Magus Dominus, a mage lord who sidestepped annihilation—at least for now. Solitude defined Perry's existence until his arrival in Ro'an shattered that isolation. Suddenly he occupies the place of favored son to his devoted servant and stepbrother to a volatile Storm mage wielder. Armed with their loyalty, Perry builds the foundations of lordship and defense across his lands. Between subduing encroaching beasts and aiding desperate souls, he discovers that mechanics and fighters serve one eternal purpose: to protect what matters. -Progression Fantasy with light LitRPG elements -No romance -Kingdom building and magic progression
