Archons (plural: Archon) are an advanced form of L'Cie in the Inheritance Series that have two L'Cie Brands instead of one and are considered very rare, if they somehow complete both (or in some case, the single) Focuses that are given within a time limit they are not turned into Crystal and both of their Brands turn white, Archons are effectively Immortal and therefore will not die from age (as they no long physically age) nor disease.
