mae taverbis from the comics and many others. Tevinters arent all monsters, fair amount but not all and most of what you saying is somewhat inaccurate
I never said they are all monsters. Even Fenris, the man who hates Tevinter and the magisters more than anyone else we've met so far, says he has no doubt that some magisters are noble. But they are the vast minority.
Dorian says there are Tevinter mages who are slaves. If by "magister don't care" you mean someone can be set up so that his citizenship can be taken away then you would be correct. But the fact remains that it needs to be taken away or they can't be made a slave. This was exactly how it used to be in Rome. Citizenship was everything.
No I never said she is awesome. I said excellence is rewarded in the empire regardless of origin. Funny you mention Tevinter stories, there are many stories of heroes rising from slave origin. But there are no stories of an elf leaving poverty and disease-ridden alienages. Grey wardens don't count since everyone can escape to the wardens, its hardly a better life.
Tevinter mages can also mean "slaves owned by Tevinter". For example cattle owned by people in Texas are known as Texan cattle. That is what I mean, yes. With a word, a magister can send someone from being a citizen to being a slave. Plus comparing Tevinter to Rome isn't something that should be seen as a positive.
The elf thing was before your edit actually. Are their elf heroes rising from slave origin, or just slaves in general? Also there are elves who have gone quit high in life. For example Briala can become a member in the Orlesian Court, perhaps the most racist against elves country in Southern Thedas.
Plus I'm referring to Codex entries written by Tevinter magisters themselves about things they did by stories.
