As Lloyd’s success attracts attention from powerful nobles and threatens the original novel’s plot, he must navigate political intrigue and magical dangers while avoiding death flags. With his loyal knight Javier and growing allies, Lloyd proves that engineering genius and creative problem-solving can be more powerful than swords in building an empire.
