The Warriors of Light, also known as Light Warriors, is a recurring theme in the Final Fantasy series. Four heroes are chosen by the crystals, by a prophecy, a will, or by fate, to go on the dangerous journey to fight the evil or simply restore balance to the world. In the games they appear in, the Light warriors are always the playable characters controlled by the player.
In Final Fantasy I, The Warriors of Light of Final Fantasy are four youths spoken of in Lukahn's prophecy that appear in Cornelia to save the captured Princess Sarah from the clutches of the corrupted knight, Garland. Unlike later appearances, these Warriors each hold the crystals themselves.
Their mission is not to save the crystals, but to destroy the Four Fiends of each of the four elements and to save the world. These Light Warriors are not given names, and instead are named by the player. Their job classes are also assigned by the player at the start of the game.
In Dissidia, the Warrior of Light is the protagonist representing the original Final Fantasy in the Dissidia series, modeled after the Warrior class from said game. The Warriors of Cosmos, chosen representatives of the Goddess, are also often referred to as the "Warriors of Light".
