An FFXII event with Balthier and Fran as Sky pirates in Heavensward looking for nethicite. This will coincide with the gunner class that will be released with 3.0 and the theme of taking to the skies. Upon interacting with the duo you realize that they are not actually looking for nethicite but rather, a lost civilization that housed Ultima the High Seraph. You will then have to fight her dealing with all the mechanics you faced in FFXII including Reverse and Holyja among the few.

You will also get their clothes and FFXII themed weapons for each class/job. For the Extreme version of the fight Ultima will use Eschaton twice (the cutscene is included and picture your party in place of the morbol) with the first dealing high raid damage and the second one acting as her enrage. You can look on youtube as to how this fight plays out and all I can say is that it will be hell for healers and tanks.
