Not (Just) a Mage Lord Isekai 1

Perry liked being a mechanic. Now he's a mage lord. When Perry gets isekai’d into a young noble with newfound magical powers, he must choose between surviving on the Front, a mystical battleground with sky-high mortality, or pledging an oath to become a Magus Dominus. A mage lord. The title sounds nice, but the responsibilities are punishing. Perry must develop and protect a domain in the hostile north. His grasp on magic leaves much to be desired, but with the help of a loyal servant and his half-sister, a tempestuous Storm mage, he has a fighting chance. But his most potent superpower is his experience from Earth—and his mindset as a mechanic. Who knew blending schematics and spellcraft would work so well? Dive into an epic adventure that follows a mage-engineer MC carving out a domain on the frontier. Perfect for fans of Ends of Magic and Bog Standard Isekai!
