Fomortiis

Formortiis, usually refered to as the Demon King, is the leader of the Monsters in Fire Emblem: The Sacred Stones and serves as its main antagonist and final boss. Eight hundred years before the events of the game, Formortiis was defeated by the Five Heroes, their Sacred Twin weapons and the Sacred Stones.

Story
Fomortiis is known to be the ruler of the Monsters that terrorized the world eight hundred years before the beginning of the world. In Chapter 4, monsters once said to be servants of the Demon King start reappearing, which is interpreted as a sign of his resurection.

In chapter 10, Duessel mention that Lyon created a Dark Stone that is more powerful than the Sacred Stones to Ephraim, which mentions that the Demon King was sealed by the Sacred Stone implying that the Dark Stone is incredible strong. In chapter 11 Riev appears and celebrate the rebirth of the Demon King.

It is later revealed that one year prior to the beginning of the game, Lyon studied the properties of the Sacred Stone of Grado, the Fire Emblem, said to be the prison of Fomortiis' soul and was possessed by it while searching for a way to heal his ill father. The Fire Emblem was then separated in two half the original sacred stone and the Dark Stone. The former was later destroyed by a now possessed Lyon.

During the rest of the game, Lyon is gradually corrupted by the Demon King who uses his body as a host commanding the Grado armies and ordering the destruction of the remaining Sacred Stones. At the end of the game, Lyon manages to destroy all the remaining Sacred Stone except the one from Rausten and eventually dies at Demon King altar allowing the Demon King to return in the flesh. His soul is still bound to the Stone of Rausten however and once his actual body is destroyed, what remains of his soul is trapped in the Sacred Stone.
