The Great Crystal , is a location in the land of Ivalice in Final Fantasy XII. It is a large crystal located in the deepest reaches of the Giruvegan. The player won't get a true map of the area, but a sketch of the outside of the crystal, and an indication showing an approximation of where they are from the outside (near the bottom, as opposed to near the top). The core of the crystal is a great orb of magicite, constantly spewing Mist. Though the party speculates that it might be nethicite, its exact nature is unclear.
