So wait, what's the hierarchy for these people? Is it like:

Hydaelyn (Highest power)
The Twelve
Paragons
The Primals (lowest Power)

I'm gonna just say our "primal" is Hydaelyn. Only because that's what SE would do. As players, we are in some way stronger than everyone else (beastymen). Hydaelyn sees us as more than beastymen, so she uses us to protect the planet from the beastymen primals and the Empire. Empire was gonna destroy most of Eorzea (and part of Hydaelyn by proxy), so she awakens us to her presence. She gives us the power, not only to defeat the beastymen and their primals, but the Empire as well. Remember, it stresses the planet (and her) each time the primals are released, so she gives us power to stop the primals.

But then, why does Lu send us into a time warp using Thaliak? Wouldn't Hydaelyn save us? Maybe she ordered Thaliak to cast us into a time warp (or crystal stasis) to protect us. She may have been bracing for impact from Meteor and couldn't teleport us so she had Thaliak (and Lu) do it for her.

I dunno. I wanna believe we are important, more important and powerful than the beastymen. We wouldn't just have a primal, but Hydaelyn herself.
