How can people even talk about being "chosen" in this game? From a lore standpoint, which one of us was the one who brought down Ifrit? Surely it couldn't have been all million people playing the game! I mean, in the story, there is only one Ifrit, and he was only a threat once (for simplicity sake, going with story mode). It could be just as conceivable that lots of people are "chosen" to become padjal if the times called for it. But my theory is a little more blunt:

I think the idea of a blood-soaked axe-wielding MRD padjal just seems dumb, given their nature (regardless of prior race).
