Prentice Alvin
Eventually, Alvin is forced into helping Arthur to escape from some slavehunters, which requires him to change Arthur's DNA enough to prevent the hunters fromage using their "knacks" (special powers) to find him. Alvin also creates a plow of living gold, which is bestowed with magic, as his journeyman works to release himself from his apprenticeship as a Smith and also as a Maker.
