On the 13th Shard Warriors used Auracite to trap primals and used that power until it corrupted them and made the 13th Shard the World of Darkness.
In the Ivalice raid Ultima is show making Auracite. So, was she originally summoned to the 13th Shard or did she originate from there and get summoned here to destroy the city of Mullonde?
Also if Voidsent were created by auracite what are the Sin Eaters created by? That being said are all voidsent created by the auracite or is that just the more powerful ones like Cloud of Darkness, with the lesser voidsent just manifesting from the darkness. Which still leaves that the more powerful Sin Eaters were created similarly or are they just manifestations of the light?
What do you think?
