In the Kingdom of Montesis, where magic is forbidden, Don (Sei-naru Shaw), a 129-year-old technician and repairman with elemental abilities, dreams of protecting María and creating a tranquil home. His life changes when he feels the call to become a Protector to maintain order and world peace, just as his parents once did in his forgotten past. The journey begins when Don falls in love with the beauty and culture of the Kingdom of Montesis during his first expedition. This world is divided between two magical forces: positive ether and negative ether (“the Nothing”), the latter governing Don and turning him into a magnet for the dark forces of the underworld. As the sole survivor of his race, Don becomes the target of the most powerful king on Earth and of Mei-Wei, one of the most influential women due to her special medicines. The conflict intensifies after the destruction of his village, the murder of his master, and the killing of his platonic love—María’s mother—a deed that took place following the appearance of an underworld prince, who plans to unleash chaos throughout the forest. Consumed by vengeance, Don accepts Mei-Wei’s offer, though he refuses to become what his father was—the Protector—thus revealing his darkest and most apathetic side. While the kingdom’s defenders outmatch him in strength, Don will compensate with cunning tactics and brutal violence, beginning his descent into darkness. Yet an inner voice persists, warning him of the consequences and trying to steer him back onto the path of good.
