Demon Light (不浄の魔光 Fujō no makō, lit. Corrupted Demonic Light) is exclusively used by Fomortiis in Fire Emblem: The Sacred Stones. When cast, masses of corrupted light will swirl into the depths of Fomortiis' eyes, causing them to glow with a sinister aura. As this wicked glow dissipates, the selected enemy target will be inundated by a concentration of twisted, befouled energies, sustaining copious amounts of damage in the process. Within the game's data, this weapon is described as "a malefic flash that destroys everything it touches".
