It is very possible that the song is indeed talking about the primals, or rather that the primals are the ones talking. Which really makes me wonder, who are they talking to? Who is the other in the song? Is it still Hydaelyn? Is it us? Or are they addressing the Allagans?
Listening to the song again while considering the idea that it is a plea by the Primals, you can't help but feel sorry for them. They're constantly forced into this existence only to be killed. I think I'm gonna lay off the primals for a bit.....
