The fifth expansion for Final Fantasy XI, Seekers of Adoulin, was announced at VanaFest 2012, a celebration of the tenth anniversary of the Japanese launch of the game, in Yokohama, Japan. Two new jobs are featured in the new expansion, Geomancer and Rune Fencer. The expansion also contains seven powerful bosses, and a new western continent called Adoulin. Because it is the last game released on the PlayStation 2 in Asia, Seekers of Adoulin will not be available on PlayStation 2 outside of Japan.
