Wrathion's goals could be something we, the heroes, truly desire. It may simply be that it involves transitional periods we won't like.
Raw iron ore may want to become a sword, and the blacksmith promises to make it into a fantastic sword. The iron may be rather unhappily surprised when it gets thrown in a blazing fire and beaten by a hammer, even if it does become the sword it wanted to be. The blacksmith may not bother to explain, thinking it too obvious to mention, or the iron to dim to understand even if he explained.
I'd like it if Wrathion was that blacksmith.
