Alzi had a promising future. At seventeen, the Goddesses blessed her with a life affinity—a rarity for commoners in a small village; a few days before the class-choosing ceremony, her Mother gets sick. After using her little mana to keep her alive, she runs to the capital to find a true healer. With no money, she sells herself into slavery for a decade. The decade is almost up, but she has been turned into a broodmare for the nobles and faces a sale to keep her enslavement going.
