Final Fantasy XI: The Nations
In Final Fantasy XI there are 3 optional Nations to start your character in. They are Bastok, San d'Oria, and Windurst. Each hometown offers their own individual specialities, like Guilds, Quests (which lead to Fame) and Missions. The other nations, Jeuno and Aht Urhgan, are where higher-level characters interact and spend the most time.
The Republic of Bastok
Bastok is home to most Humes. It is a dusty, mountainious region where lots of mining and resourcing are done. The characters in Bastok enjoy hunting for treasure and keep their economic system very active.
The Federation of Windurst
Windurst is home to most Tarutaru and Mithra. They are very close to nature, and keep the forest around the well kept. The history goes that years before the Tarutaru called on the Mithra to help them battle the war with the neighbouring Yagudo, the beastly birdmen. Currently the peace is delicate, but together the Tarutaru and Mithra keep their home safe. Most characters in Windurst are very friendly and more eager to make friends and help others than to dominate other regions.
The Kingdom of San d'Oria
San d'Oria is home to most Elvaan. Characters in this region are more quiet, reserved, and full of pride. They are quick to battle and strive to become more powerful.
The Grand Duchy of Jeuno
Jeuno isn't so much a home, but the central connecting bridge between the other 3 nations. This is where a lot of action is founded, high level characters looking for others to complete important missions and quests. The economy here is booming, the most expensive place to bid and sell items.
The Empire of Aht Urhgan
The Empire of Aht Urhgan lies to the east of the Middle Lands of Vana'diel and takes up most of the Aradjiah Continent. For years, Aht Urhgan was isolated from the Western world but recently (with the release of Treasures of Aht Urhgan) reconnected with Jeuno. Aht Urhgan is presently at war with the beastmen of the near east, and with the Far Eastern countries (which have yet to be revealled).
The fortified city of Al Zahbi serves as the capital of West Aht Urhgan is composed of two areas - the Commoner's Ward (Al Zahbi) and the Merchant's Ward (Aht Urhgan Whitegate). At present, this is usually the most crowded area of FFXI.
Al Zahbi shares its Auction House with Jeuno.
