Final Fantasy XI, now in it’s 18th year of service, continues to receive regular small-scale updates to its content and features, but it’s been a minute since new story content’s been added — specifically 2015’s Rhapsodies of Vana’diel — in what seemed to be a book-end to the game’s tale.

Producer Akihiko Matsui, in a post introducing the August update, shares that you’ll need to complete the Rhapsodies of Vana’diel to experience the new stuff:

“The most exciting news I have to share is that a brand-new storyline will be coming to Vana’diel! This story, which will play out over the course of many version updates rather than just a few, explores a side of Vana’diel that’s never before seen the light. Be aware that full completion of Rhapsodies of Vana’diel is required to experience this wonderful new content, so I hope that those of you who haven’t set experienced Iroha’s tale in full will take this opportunity to do so.”

In addition to story content, the August update will include new and updated monthly objectives to the Records of Eminence, changes to Beastmaster with the philosophy that the Job should have more synergy with their pet, new Normal and Intense Ambuscade enemies, new recipes and items.

Final Fantasy XI is available now on Windows PC.
