Crixus Oran, a water artisan, and engineer renowned for constructing aqueducts and piping in the opulent bathhouses and mansions of the Rond Empire, faces a critical juncture. Tasked by his guild with safeguarding a substantial sum of gold, he succumbs to a misguided ambition – attempting to secure enough wealth in a card game to purchase an extravagant residence for his new fiancée, Kharrina. Regrettably, he loses the entire guild's gold in this ill-fated endeavor. Within the inaugural installment of the Aqua Pure Trilogy, Crixus, seeking redemption, secures employment with the Lamiae of Nostrum. This society, marked by cruelty, sees the privileged few at the pinnacle indulging in bathing with the lifeblood of those relegated to the lower echelons. As Crixus grapples with his choices, a pivotal question looms – will his conscience permit him to fulfill his obligations, or will moral quandaries alter the course of his actions?
