OMG what makes you think this woman was treated any differently than any other mage? She was a trained pet in the court originally, not much better than a jester. They underestimated her ambition and intelligence and she had the gumption to rise to be more than they could have expected. She knew how to work the system to get where she was, no one just handed it to her!
She is the very example of what mages can do if they just had some gumption instead of whining about how 'life isn't fair!' 'I'm a victim!' 'Gimme!'
Frankly, all this thread has done is made me want her in my group even more than I did at first glance.
I get what you're trying to say here, really I do and to an extent I even agree with you.
Firstly, I agree that Vivienne's ability to rise to her current position is to be respected, her achievement is proof that a mage can be more than the power they wield.
However, they prime issue here isn't Vivienne's talent, work ethic or lack thereof, but the fact the system itself is rigged (magic is to serve man, never to rule over him). It is not simply a matter of working hard and you'll succeed, mages actively and legally denied from wielding political power.
And also, not to detract her achievements, but in my opinion a lot of her success was dependent on the culture of Orlais, the 'Great Game' and the fact that Celene was the ruler at the time. I mean consider this, what if Gaspard had been the ruler instead, could she have risen to the position she did without the political atmosphere that Celene engendered? maybe, but I doubt it.
Like I said before, I agree that for her achievements she should be respected, but we mustn't underestimate the effect that external forces had to help create those achievements.
