What elf origin do you want to see in Dragon Age Dreadwolf?

I don't think it is any worse than being down south and, as I say above, there is the possibility for advancement given the right circumstances. There has been a tendency to suggest that the majority of slaves in Tevinter are elves, when according to WoT it is about half and half elf and human. The majority of free elves tend to live in poverty and it is a matter of opinion if that makes you better or worse off than in the south but I never got the impression that they experience the sort of prejudice found in the south, which was very much a result of Chantry propaganda after the Exalted March on the Dales. Tevinter definitely doesn't have alienages.

Of course, the Dalish are a different matter. I understood from DA2 that the Dalish don't go anywhere near Tevinter for good reason, since it is even more the evil empire in their lore than Orlais. Also, as non-citizens they would be vulnerable to slave traders. Yet, in Tevinter Nights there are clans up in Tevinter, some outside of the Arlathan Forest, so I don't know if that is a new development or not. The Tevinter squadron attacked them but since they had no rights, being effectively foreign intruders, that would probably be the case for anyone.

I know comic series aren't necessarily anything to go by but in Magekiller their contact on behalf of the Archon was an elf.   I can't remember if he was a Liberati or not but certainly his circumstances seemed good enough he didn't immediately leave his service when he had the chance.    I suppose it could have been a similar situation to Briala but clearly not something that the Archon had to hide, so not quite the stigma about having an elf as an acknowledged valued assistant as there is in Orlais.

The dodgy part about being an elf in Tevinter is their value in blood magic.   Presumably it is still known as it was in ancient times that elf blood has magical properties not found in other races, making them more likely to be victims.   The difference is that, unlike in ancient times, now it has to be done behind closed doors because officially it is meant to be forbidden, although in practice every Altus family knows how to do it.
