Renan Saneris is seventeen and still classless in a world where everyone else has already found their calling. While etching runes into a blade as a gift for his best friend Yana, the glyphs glow and the system grants him the Class 'Artificer' — a discipline so rare no one in the kingdom has heard of it. With no teacher and no guide, Renan must reverse-engineer what his new powers can do through trial, experiment, and danger.

Renan is curious, methodical, and earnest — a young man who compensates for his late start by throwing himself into research and invention. His partnership with Yana grounds the series emotionally, giving him someone to protect and someone who challenges him. He is not overpowered but grows steadily through the application of intelligence rather than lucky power spikes.

Across two books, Renan and Yana investigate demon threats emerging from ancient ruins, run afoul of the Silver Circle mage guild, and begin unraveling why Artifice was suppressed and why magic itself is strictly regulated. The series balances dungeon exploration and combat with Renan's systematic discovery of his crafting abilities — each book ending with the mystery of Artifice deepening.
