About FFXIV races information

The Elezen are a characteristically tall people, long of limb and slender of build. They are also possessed of a somewhat extended lifespan in comparison to the Hyur. The Elezen once claimed sole dominion over Eorzea, their presence predating that of the other races, and, as such, developed a heightened sense of honor and pride. In years past, the Hyur migration into Elezen lands sparked bitter conflict. At present, however, the mutual understanding reached between the two races allows them to work towards mutual peace and prosperity.
Ultimately the Elezen diverged into the two clans that exist today. The Wildwood took to the forests to protect their homeland, while the Duskwight withdrew to caves and subterrane, opting to avoid all contact with any but their own.
