With focus returning to the Final Days of the Star, a question suddenly came to mind as to its beginning. Back in Stormblood, somehow both Shinryu and Firemane Midgardsormr were able to weaponize star formation with the Protostar attack. Even weirder, the Allagans managed to get Proto-Ultima simulate a core-collapse Supernova with its internal reactor. Now granted, those entities were all much smaller than both the Source and the Daystar that illuminates it, but given how strange astrophysics is in Final Fantasy XIV I wonder where the pre-sundered Star (and Dragon Star) came from and if the Protostar/Supernova literally involves creation of miniaturized stars.
