An Avvar origin in Veilguard?

Since we're in the north and actually going to Rivain I'd rather a Rivaini seer/pantheist origin, someone raised amoung the Rivaini spirit practises.

Avvar would have been a great origin for dao or dai though.

As others have said, I think it unlikely unless they turn up as a slave. I think they dealt with that culture in JoH. There is an off chance that we could see that group we sent north, perhaps as an optional side-quest, since I think there were some world states where they are dead (not sure about that).

I'm still hoping we might get a Rivaini Wise Woman but I think they seem to have lost interest in them and are now promoting the Lords of Fortune, even though we had never heard of them up to the Tevinter Nights short stories, which I find very odd considering their main focus of interest, treasure hunting including ancient artifacts, which should have had them cross paths with us before. It may well be it will be Mateo from Tevinter Nights as he was already being employed by people searching for clues about Solas.

I think we will get a Crow from Antiva, likely the female Crow we have seen in concept art. We may also pick a Qunari there, also likely female.

I definitely hope the Grey Warden is Davrin from the Behind the Scenes video and that they won't kill him off like they did Mhari after you start to like him. May be there will be more than one.

As for our own origin, I still think it more likely we will be a slave that is liberated by the fighting on the east side of Tevinter. I don't see how we could have the PC origin as Crow, as it would be limited to human or elf. I suppose a Lord of Fortune could just about be any race and stretching a point, a Grey Warden could be too, since there are Qunari outposts on that side of Thedas and a Tal'Vashoth could have joined up or even a devout Qunari under orders from their priesthood to gain knowledge of fighting darkspawn.

When it comes to Tevinter, the most likely PC background would be Sicarri. This would be interesting as they are normally slaves who are kept loyal because their families are held hostage. So that could have an interesting personal quest where we want to rescue them so we are fully free. Since they are slaves, they could be any race (even dwarf because it would be possible make casteless slaves without offending the Ambassadoria) and any class.
