Alright so… Here’s some info that I wrote up.

[quote=Disc Info: Skybound Dragon]

A disc containing the fragmented memories of Vaan. While not all of the memories of a single version of him could be found within the disc, it is most notable for giving its Driver the ability to use Quickenings, powerful spells from the world of Ivalice albeit due to the sheer power of the spells, not just anyone could handle the usage of Quickenings which soon deemed the Skybound Dragon disc to be more dangerous than some of the other discs that had fallen. The disc currently is in the possession of Hoshi, an artificial humanoid that was created by the world government.[/quote]
