Besieged

Besieged is a new system that has been added to Final Fantasy XI by the expansion Treasures of Aht Urhgan. The system is calculated weekly, like the Conquest system, but it deals with the New World or Near East, the new continent that this expansion has added. Unlike Conquest, it is assumed that the beastmen are in an uprise against the nation of Aht Urhgan. Conquest deals only with the ballance of power between the beastmen hordes and Aht Urhgan's Mercenaries (a roll that the player characters fill).
