The Ascians have not once mentioned what the world's original name was pre-Terminus (it was simply referred to as 'the Star'), and with Zodiark banished to the moon (which he continues to be associated with as a 'darkness' god), it is still correct to call the planet Hydaelyn, simply for lack of a better alternative (it should also be worth mentioning that FFXIV's setting metawise is more often than not called Eorzea as a world rather than just a geographical region it actually is, but this does not really count).
Pretty sure this isn't altogether accurate. Yes there was devastation on a huge scale on the original star, but it certainly didn't cease to exist. We visit the actual ruins of an Amaurotine city on the First; if the Terminus event destroyed an entire star they wouldn't be there. Yes the star was split into fourteen as were the souls that lived upon it, and at some point on the Source we started to call the star Hydaelyn after its 'creator'. Or perhaps it was always called Hydaelyn and the summoners named their primal after the star (less likely since Zodiark is the one who is actually the manifestation of the will of the star so perhaps it was called Zodiark before)
