Fomortiis is a highly ominous demonic being in control of Lyon. Fomortiis twists Lyon's feelings towards the twins Eirika and Ephraim; fueling jealousy towards Ephraim for his strength and gallant nature and corrupting his love for Eirika into almost a lustful desire to make her his. Fomortiis is an incarnation of pure evil who simply wishes to control worlds with his power. He makes offers of power and wish fulfillment such as the reincarnation of a loved one should one ally with him.
