I would say 'when' and not 'if'; change always invites backlash for those valuing stability more so...and there has been an abundance of change. That could make the backlash even stronger.

Ah, I see. The Grey Wardens are an organization that includes all races, nationalities, mage and non-mage, kings and criminals...it's sole purpose is to stop Thedas from being lost to the Blights. You might have heard that term before, but just in case no one has explained, I'll do so. A Blight happens when a horde of darkspawn -tainted beings whose only purpose is to kill and corrupt- are lead to the surface by an archdemon. Most darkspawn possess a feral cunning and no more...but when they find and taint an Old God in the Deep Roads, it's another matter entirely. An archdemon is intelligent, powerful and only killing it will end a Blight. And only Grey Wardens are capable of doing so.
