Wrathion is one of those unique and entertaining characters who appeared out of nowhere and managed a staggering degree of complexity in just a few short years in game. Although he was not introduced by name until the tail end of Cataclysm, his origins began when the expansion revamped level 1-60 content and consequentially introduced a bizarre and touching origin story in the Badlands. It wasn't until the legendary quest chain for rogues that we got a real look at Wrathion, newly hatched and remarkably intelligent for his age.
Once his tasks for rogues were over at the end of the expansion, Wrathion departed -- and then promptly showed up again in Mists of Pandaria, in a far more extensive role that stretched the length of the expansion, and beyond. But one thing has always been incredibly unclear -- exactly what Wrathion is up to, and why he is doing what he's doing. He's given us a reasonable enough answer, but can we really trust the last remaining member of a dragonflight known for lies, deceit, and evil, even if he is supposedly uncorrupted?
