First and foremost we learn our little masked and robed friend has the Echo and is apparently from a whole 'nuther world/star which from his description is reminiscent again of FF6 and the World of Ruin (it can be argued that Auracite has also been used in FFXII/Tactics to summon/bestow one's self with power and we don't know what happened to Ivalice after Vagrant Story, but FF6 fits the referential material more).
Auracite is strictly Ivalice. So XII, Tactics, Tactics Advance and Vagrant.
VI's magicite is the result of an esper dying/losing all of its power. The themes are similar, but the actual material of Auracite is much much different.
