Fomortiis Husbando

Fomortiis is a giant horned demon known as the Demon King and is the true main antagonist, as well as the final boss of Fire Emblem: The Sacred Stones. In year 3, the Five Heroes trapped the Demon King's soul using the Sacred Stones. The stone of Grado (also known as the Fire Emblem) holds the soul of Fomortiis. Eight-hundred years later in year 803, Vigarde, the Emperor of Grado, dies and his son Lyon then tries to bring him back to life using the power of the Sacred Stones. Lyon succeeds, but in the process gets possessed by Fomortiis (Eirika's route) or has his darkest emotions and thoughts strengthened by the Demon King (Ephraim's route). Regardless of the route the player picks, after Lyon's death, Fomortiis manages to resurrect himself. He fights Ephraim, Eirika and their allies, but is unable to withstand their assault. Defeated, the two seal his soul in Sacred Stone of Rausten before they destroy his body, to ensure that he will never be resurrected again. Fomortiis is a highly ominous demonic being in control of Lyon. Depending on the route, glimpses of his grip on the young prince appear in, he has far less control over Lyon in Ephraim's route, choosing to manipulate his thoughts and only appearing as a last resort. In Eirika's route, he is far more direct in his control and has consumed Lyon's psyche.
