The elves in original Final Fantasy are a peaceful race that reside in Elfheim. Their leader is the Prince of Elfheim, and they are related to the Dark Elves, the leader of whom has cast the Prince of Elfheim into a deep sleep. The Elf King and his descendants were trusted with the Mystic Key by the royal family of Cornelia, to keep until the fabled Warriors of Light arrived in Elfheim to claim it. Because the elves have four magic shops in their town and are of relatively small stature, it could be assumed that they favor magic over physical might.
A Dark Elf stole the Crystal from Troia, and took it into his lair in the Lodestone Cavern that has a powerful magnetic field inside. Edward uses his harp through the Whisperweed to disband the magnetic field and give Cecil's party a chance to equip metal weapons and fight the Dark Elf.
The Dark Elf's spirit resides in the Crystal Chamber of the Lodestone Cavern and attacks Palom and Leonora. When the elf transforms into a dragon, he resists their magic. The Mysterious Girl destroys him with the Eidolon, Shiva.
The elves live in Arbor. They appear humanoid, but keep to themselves. The forest of Arbor is considered sacred by the elves and trespassing humans are turned into plants. The elves have the power to converse with animals, and to turn people into animals as well. The elves are led by the Queen who resides in Arbor.
The Elves make an appearance in this game; Freyr, the secret identity of the Gramps, is their king.
An elf is a type of supernatural being in Germanic mythology and folklore. Elves entered the 20th-century high fantasy genre in the wake of works published by authors such as J. R. R. Tolkien.
