This is not true in FFXIV. It is the origin of Ultima in Tactics, but none of that information can be assumed to be canon for FFXIV unless FFXIV says it is. And in the case of Ultima, we do know the circumstances around her showing up on Hydaelyn. Which is that she's from some other planet/dimension like Omega and Midgardsormr are. We also don't know when Ultima came to Hydaelyn. We just know that Hydaelyn was much stronger when Ultima came as Hydaelyn was the one to seal her initially. Which is something she most likely doesn't have the strength to do anymore. There's also how it seems that Ultima was the inspiration for the Ultima line of weapons in Allaga which suggest she came to Eorzea before the 3rd Astral Era at the latest.

Also, Unukalhai implicated the fall of the Thirteenth World on auracite, suggesting she was able to disseminate the stones across all the shards or copies of Ultima were summoned on the other worlds.
There are several type of auracite in FFXIV. Many of which have nothing to do with Ultima. White Auracite is used by the Warrior of Light to contain Ascian souls and it is a manufactured auracyte by the Sharlayans. The auracite that was used on the 13th Shard most likely has nothing to do with Ultima because not only is Ultima not on the 1st Shard, but also because it is more then likely that the 13th Shard was Flooded with Darkness long before Ultima ever came to Hydaelyn.
