Repair is a reincarnated soul who chose to come back as a Metalman, an ancient race of sentient constructs thought extinct, in a city undergoing a magical-industrial revolution. Legally owned by the Gnome Research Institute that revived him, he must work off his debt while navigating a society that does not recognize him as a person. His only real friend is Greebo, a goblin who helps him find his footing as a dungeon diver and crafter.

Repair is methodical and cautious, a former human who must relearn the world through a mechanical body incapable of eating, sleeping, or expressing emotion through a face. He leans on friendship and ingenuity more than raw power, and his 40% combat debuff forces him to think creatively rather than fight straight. Readers who prefer clever protagonists over overpowered ones will find him refreshingly grounded.

Across three books, Repair grinds through dungeon levels, develops novel crafting technology the city has never seen, and fights to prove his sentience to a society structured against him. His arc is one of incremental freedom—each book raising the stakes of what he stands to lose as his circle of allies and enemies grows. Themes of belonging, systemic prejudice, and the definition of personhood run beneath the action.
