Lunarian

Lunarians are a race of moon inhabitants from Final Fantasy IV. Many years prior to the events of the game, they lived on a planet between "the Red Planet" (Mars) and "the Great Behemoth" (Jupiter). However, their planet was about to be destroyed, so the Lunarians fled. They came to "the Blue Planet" (Earth), but humans were still in the process of evolution. The Lunarians decided to sleep and await the day the humans could understand and live peacefully with them, so a second moon was created. The Lunarians went to sleep near the moon's core, while one of them, Fusoya, stood guard over them. The only entrance to the path to the core was concealed underneath the Crystal Palace. Fusoya's brother, Kluya, eventually built an airship known as the Lunar Whale to travel to Earth. Kluya taught the people there advanced technology such as Airship building and the Devil's Road, and taught them the secret of magic. Kluya also fathered two sons, Cecil Harvey and Theodore Harvey. Kluya was eventually killed by a group of "angry humans" and his spirit came to rest atop Mount Ordeals.

Although the majority of Lunarians were content to sleep, Zemus believed that they should use the Giant of Babil to destroy humanity and leave Earth to the Lunarians. It is for this reason, as well as the protection of the Lunarians as a whole, that Fusoya sealed Zemus and forced him to sleep. Though asleep, Zemus was still able to use his immense psychic powers to control others tainted with darkness. He was eventually able to take control of Theodore Harvey, and christened him Golbez. Golbez's Lunarian blood made him even more susceptible to Zemus' manipulations.

Under Zemus' control, Golbez gathered the eight Crystals of Earth and activated the planetary elevator within the Tower of Babil, transporting the Giant of Babil to Earth. Through the combined efforts of Cecil Harvey and his allies, the Giant was destroyed and Golbez was freed from Zemus' control. Golbez returned to the moon with Fusoya, intent on killing Zemus for all he had done. Confronting him in the moon's core, the two were able to kill Zemus, but his hatred survived and developed a consciousness of its own, becoming the beast Zeromus.

In Final Fantasy IV: The After, the moon returns to Earth's orbit. Fusoya and Golbez must fight Minus, who revives Zeromus to attack them. Golbez manages to escape to Earth, but Fusoya remains behind as Zeromus destroys the Crystal Palace with his Big Bang attack. Fusoya was killed, but it is not confirmed if the Lunarians were destroyed as well.

Physically, Lunarians appear identical to humans, although if Fusoya's physical appearance is any indication they are very long-lived. Cecil and Golbez possess no distinictive physical traits that would identify their heritage, and Fusoya furthermore claims that Cecil looks exactly like Kluya in his youth. Lunarians appear to be natural mages, and Golbez, Zemus and Fusoya all know the ultimate magic Meteor as well as a variety of other high-level spells, and the spirit of Kluya is able to grant Meteor to Tellah as well.
