My Rare Class is Artificer!
"Engineering is the closest thing to Magic that will ever exist." - Yoshi Yoshimura
Yoshi Yoshimura spent his career turning impossible blueprints into working steel, right up until the night his own government decided his genius was worth more dead than employed. A stolen weapon design, a spy in his bed, and one bullet later, that career was over.
He wakes up as the second son of a noble house too poor to matter, in a world that has never seen gunpowder, steel weapons, or a rail line, holding the rarest class anyone in the kingdom has ever heard of: Artificer. His new family is drowning in debt, sitting on land nobody else wants, one bad harvest from losing everything.
He can't cast a single spell. He's never held a sword. What he can do is look at a broken kingdom and see exactly what's missing, then build it, one invention at a time, before the debt collectors and a hungrier neighboring duchy work out that a starving house is an easy house to take.
