The first game doesn't have one, and XI's is currently unknown. So they are being excluded.
II: Luminaries of the Legendary Line
III: The Seeds of Salvation
IV: Chapters of the Chosen
V: Hand of the Heavenly Bride
VI: Realms of Revelation
VII: Warriors of Eden
VIII: Journey of the Cursed King
IX: Sentinels of the Starry Sky
X: Awakening of the Five Tribes
Warriors of Eden or Journey of the Cursed King takes this for me.
