There are many different races in Eorzea, but so far there are only five playable races in Final Fantasy XIV, all similar to the races from Final Fantasy XI.
Over the course of some one thousand years and three great migratory waves, the Hyur have come to be the most populous of the civilized races in Eorzea. Compared to the others, theirs is an average physique, both in terms of height and build - a race that closely resembles humes from FFXI - The Hyur champion personal freedom and liberty, and their espousal of an eclectic variety of languages and traditions is a legacy of their diverse heritage. They are divided into the Midlanders and the Highlanders.
The Miqo'te are cat-like humanoids divided into two religious sects: the Seekers of the Sun, who are dedicated to the sun goddess Azeyma the Warden, and the nocturnal Keepers of the Moon, who are dedicated to the moon goddess Menphina the Lover. Player character Miqo'te are not limited to the two aforementioned goddesses, however; they may follow any deity of their choosing. Miqo'te are similar to the Mithra from XI.
The Elezen are 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. The Elezen is broken into two groups - The Wildwood Elezen and The Duskwight Elezen.
The Roegadyn are easily identified by their massive, muscular frames. They are descended from a maritime people that roamed the northern seas, though many of their ancestors turned their longships south to brave the crossing into Eorzean waters. Often considered a barbaric race, the fiercely competitive Roegadyn are also known for their compassion and unswerving loyalty. Many of the greatest warriors in history were born of Roegadyn stock. The Roegadyn is broken into two groups - the Sea Wolves and the Hellsguard.
The Lalafell are a folk both rotund and diminutive. Small by any race's standards and possessed of a childlike countenance, it proves difficult for non-Lalafell to gauge an individual's age with any degree of accuracy. Originally an agricultural people inhabiting the fertile islands of the south seas, they found their way to Eorzea via the burgeoning trade routes. Lalafell are welcoming of outsiders, and share prosperous relations with all of the other races of Eorzea. The Lalafell is broken into two groups - the Plainsfolk and the Dunesfolk.
