I dunno who brought this up (could have been Moose), but I find the idea that we are tempered very interesting.

Hydaelyn tempered us. And really, have we ever thought of denying her blessing? Have we ever decided to reject her and fight her? No, because we are tempered by her. We follow her unquestionably. Also note that once tempered by one Primal, they cannot be tempered by another primal (A person tempered by Ifrit, cannot be tempered by 'ruda, no matter how powerful she thinks she is). We see this when Ifrit tried to temper us but can't because we're already tempered by Hydaelyn. We view this as being "immune" to tempering. Maybe because we were already tempered by Hydaelyn. I don't think she is "evil" at least in the same way as the primals. Maybe being tempered allows the beastmen to communicate with each other. I'd think each beastman has their own language, so being tempered allows them to communicate with everyone. Unless, are the beastmen truly "tempered"? I though they would volunteer to worship the primal, but does the primal still temper them, just in case?
