The Map Only I Can Read

Summoned to a kingdom that never wanted him, Ren is cast into the Wasteland with no magic, no class, and no way home. Until a vanishing shop grants him a map only he can read. Forgotten technology. Hidden wells. Ruins waiting to rise. He starts with one house, one field, one tool at a time. He is not here to conquer. He is here to build something the world can’t ignore.
