For all intents and purposes, a forgotten primal is a non-existent primal. It's as good as dead.
This little conundrum is really a variation of the good ol' story: If there's no one around to hear the tree fall, did the tree fall?
What do we really know? What actually is "knowledge"?
Many apologies for this digression, though. To return to the original question, we really don't know much about Hydaelyn's relation to Zodiark. I'm particularly curious about how much Ramuh actually knows of the time before mortals were created. Because if there were no mortals around who believed in him, how did he exist in the first place to remember the time before history?
Patch 2.4 spoiler, about the fate of the Students of Baldesion:
We have the first mention of a phenomenon called the "Rejoining".
That sounds suspiciously like a concept that has appeared in earlier Final Fantasy games, where the antagonists yearn to return to a nihilistic "singularity", which is presumably the state of "existence" when time began.
Why anyone would want to return to such a state of nothingness is beyond my ability to understand.
