The Burning Legion? I've never heard of that, so I doubt it. They've never seemed that organized, just in it for themselves.

[She smiles, pleasantly surprised at such an opinion of mages.]

Much of it has to do with events in the past and their connection to the Chantry, the dominant religion in Thedas. 'Magic exists to serve man, and never to rule over him.' That's one of their sayings, a way of rebelling against the mage-ruled Tevinter empire which enslaved and oppressed so many--and still do, though it's power has declined. Distrust of mages partly stems from that past, and fear of blood magic, which can be used to control others. I can't blame the latter, for I've seen what it can do. But many other mages never delve into such vile practices.

[Yes, Thedas really sucks when it comes to moderation. It's one extreme or the other.]
