Gloria, a first-year medical student, is struggling with the heavy workload and grueling curriculum when she is approached by Luther, a tall, dark, and enigmatic being with fantastic powers. Luther belongs to another humanoid-race, the Geonarians, who live parallel to humans, visible only as the elements they embody, and have traits and powers related to their respective elements. As if the medical school curriculum was not rigorous enough, he recruits her to also become a Saludarian, a healer of all Geonarians, who manages the medical maladies of these beings made of rock, plant, wind, beast, fire and water.
Gloria embarks on a journey through her four years of medical school, grappling with the challenges of becoming a quality human being and future physician, all the while combatting the malevolent side of the Geonarian race, the Nectrarians, whose only goal is to destroy all living things.
