yea but that is his job, to protect magic.  He is also right, first invasion by the legion was because of misuse of magic.  So what everyone is fighting against is their preference.

I just hope that they don't actually have you defeating him.  As killing Aspects have major consequences to the realm known as azeroth.  Wanting epics? I'm pretty sure his little (sarcasm) cave has more epic loot than any place in azeroth and outland. 

It would make no sense that another aspect would order their troops to take out another one (outside of Deathwing - who is nothing but lovable btw XD).  Especially the red dragonflight.
