I'm not sure what to make of Nero. I didn't quite catch why he wasn't killed or imprisoned once his identity became known. I suppose he wasn't actually all that loyal to the Garlean Empire after all but then rather than atoning he began obsessing over the power of darkness.
Perhaps there's something lost in translation? Is he meant to be more of a morally grey rival than an enemy?
