Final Fantasy XI’s Seekers of Adoulin now has a date for North America.

The fifth expansion in the 10 years long game is scheduled to launch on PC and Xbox 360 on March 26, 2013 – a date that coincides with the Japanese launch revealed earlier this week.

The expansion will unfold a new adventure for players as the eighth century came to a close. The Royal Family, in partnership with the Eleven Knightly Orders, has agreed to abolish imperial rule—from which arose the Sacred City of Adoulin on the Ulbuka Continent. In the blink of an eye, Adoulin had grown to be a maritime metropolis, with a mercantile prowess rivaling that of Jeuno. It is in this booming city state that the players will find themselves as they work to explore and unlock the secrets hidden in the nearby jungles.

The release of “Seekers of Adoulin” will introduce two new jobs. Geomancers harness the elemental energies of Vana’diel to aid their comrades and attack enemies alike. Rune fencers are versatile duelists, quick with a blade as well as incantations, and employ the power of arcane runes.

The expansion will also feature new gameplay systems, such as player-built outposts, new contract work, and the introduction of special “power spots” that are hidden throughout the environment for powerful character enhancements.

Also announced today is the same-day launch of Final Fantasy XI: Ultimate Collection Seekers Edition, the full compilation of the stand-alone game with all four previously released expansion packs, three add-on scenarios, and three battle area add-ons. This collector’s edition pack will be available for $39.99, and the stand-alone “Seekers of Adoulin” expansion for $29.99.
