The first conflict to arise in Greek mythology was Uranus (Sky) forcing himself upon Gaea (Earth), with effects that would be felt for eons. This is reflected in Jenova’s meteorite striking the Planet at Gaea’s Cliff, still affecting Final Fantasy VII’s plot 2,000 years later.
According to #Logos, much of the post-Fallen folktales that arose in Valisthea focused on legendary dragons. This led to widespread belief that the Mothercrystals were the calcified body parts of a great drake. The primordial mother goddess in Babylonian mythology is Tiamat, who takes a draconic form and whose corpse shapes the known world. Tiamat is a common dragon name in the Final Fantasy series.
In Final Fantasy Tactics, the player battles Cardinal Delacroix, a famed holy soldier of the 50 Years War. He is possessed by a Lucavi, the grotesque Cúchulainn. Cú Chulainn is a demigod and legendary warrior in Celtic mythology, known for transforming into a hideous monster.
According to Gnostic myth, God of the Old Testament is not the true Almighty, but rather an imperfect creator deity. Gnostics rejected this demiurge and pursued enlightenment of the Almighty. This is reflected in FFXVI through Ultima’s creation of mankind, whose greatest sin is to break free of his will.
