The official Final Fantasy XIV was recently updated with new information about the game. There’s detail about each of the clans for each race that one might find interesting. Along with clans, each race also has lore.

The Elezen

Wildwood Elezen – Possessing a keen sense of sight, the Wildwood clan are expert archers. After hundreds of years living in the forests, they have emerged to urban centers or to live more nomadic lives on the plains.

Duskwight Elezen – The Duskwight clan have the ability of detecting the faintest sounds, making them a perfect build for hand-to-hand combat. They are a bit like scavengers, robbing and pillaging to survive.

The Lalafell

Plainsfolk – The Plainsfolk live in thatched huts, with intricate passageways underground. Their long ears allow them to hear the faintest sounds.

Dunesfolk – With distinct eyes covered by a protective layer, a response to the glaring sunlight of their home region, the Dunesfolk live on structures stuck to backs of large beasts of burden.

The Hyur

Midland – The Midland are the larger of the two Hyur clans, establishing themselves through every city in the realm. They are some of the most educated members of the game.

Highlanders – Living mostly in mountainous regions of Eorzea, the Highlanders are bigger than their Midland counterparts. They are quite rare and work as mercenaries.

The Roegadyn

Sea Wolves – Besides sounding like a new species of animal you’d see at a zoo, the Sea Wolves work as sailors or naval mercenaries. Their history consists of living on islands on the north seas and working as fishermen.

Hellsguard – The Hellsguard are all about the volcanic region they inhabit – both in body and mind. They believe the mountains of flames are doorways to the underworld, making them act as gatekeepers.

The Miqo’te

Seekers of the Sun – The Seekers of the Sun have a preference for the light of day. They have a devout reverence for Azeyma the Warden, goddess of the sun.

Keepers of the Moon – These are the more nocturnal of the Miqo’te clans. They worship the goddess of the moon, Menphina the Lover.
