After retrieving the Sword of Kings, which can destroy nethicite, the party journeys to Archadia to retrieve Larsa, who has been taken. There they discover Doctor Cid, who created manufacted magicite, and who directs them to go to Giruvegan as it is the source of nethicite. In Giruvegan, only Ashe can enter the final area, where she encounters the makers of nethicite, the immortal Occuria, who "pull the strings of history"; they give her the Treaty Blade to cut new pieces of nethicite from the Sun-cryst, the source of all nethicite and its power. She learns that Venat, one of the Occuria, has defected to put the "reins of History back in the hands of Man", controlling Vayne and Cid, manipulating the former's goal to conquer Ivalice and become the new Dynast King, and leading the latter to create manufacted magicite to reduce the relative power of the Occuria. Archadia's expansion campaign was a front to capture the existing shards of nethicite.
