Luminarians are a family of creatures found in Final Fantasy XI's Al'Taieu region. Luminarians are a type of ascendant being. There are many different forms of Luminarians, most of which are referred to by descriptive names rather than their actual names, which are difficult to type or pronounce. Luminarians display different reactions towards adventurers ranging from curiosity to apathy to hostility. Luminarians are known to have rare organs and a rare type of tissue for the curious adventurer to collect. While adventurers are incapable of working with the material, there are several scientists that would give much to get a hold of such specimens.
