It is also possible that Hydaelyn's creators identified Creation Magic as the cause for the calamity, and thus one of Hydaelyn's functions would be to over time get rid of the foundations of creation magic. Which would cause the laws of reality, both aetheric and physical, to become unrecognizable to the Ancients/Ascians and thus unable to be utilized in creation magic rendering it, and the potential threats of it, inert.

We lack a lot of details about the exact events of what happened back in that first calamity other then that it began in a far off city and spread across the world from there, as it spread the Ancients lost control of their creation magic and started mass producing monsters from their deepest darkest fears, and that it started in their area with a sound from the depths of the earth. Which could very well had been a monster tunneling through the earth that had been created by a group of ancients elsewhere and help drive the underlying fear out of control, leading to panic, after it had been built up by rumors of the calamity in other cities.

If the elimination of creation magic is one of Hydaelyn's hidden functions then it could result in a possible story future where there will be no more primals, because the creation magic that allows them to come into being does not work. Allowing Hydaelyn to go to the field one last time to help us defeat a Zodiark possessed/empowered Zenos.
