Returning and new characters for Dragon Age 4

Well, as things are now either all mages are apostates and/or we will be going to Tevinter, where noone are apostates.

If the mages are given permission to rule over themselves, then the term "apostate" is probably close to being dead. It had already lost a lot of its weight during the inquisition.

And there might be mages in Tevinter, that are not a part of the political sphere, but as in "illegal mages" I seriously doubt it.

Don't keep slaves, for example? Or doesn't join to the Magisterium? No matter, still just a mage. Just a Tevinter inhabitant.
Or join/organize a slave rebellion? Become raider? Them they become an outlaw. 

"Apostate" a southern-Thedas term for a mage-criminal (doesn't want to join the Circle), who's presumably not a Maleficar/Abomination. A Mage, who does not accept Chantry's dogma. A Mage heretic. There is no sense in such a form in Tevinter.

From Origins: Sten canonically makes it back to Par Vollen so he could have a significant role in whatever Qunari events occur. I'd like to also see at least references to Shale. Maybe we could run into a pigeon-hating dwarf woman? She doesn't even need to reveal her name, and she wouldn't be important to the DA4 protagonist.

Awakening: Any one of these characters can be dead at this point but I'd love to see Nathaniel or Sigrun again! Any way they can incorporate them with whatevers happening in the Anderfels.

DA2: Feynriel could be in Tevinter. And Sandal is always cool. Otherwise I'd like to leave the Kirkwall gang in peace.

Inquisition: Dorian will probably show up one way or another, and possibly Harding or Cole, and Calpernia. Oh, and Solas I guess. I guess I could see Morrigan returning depending on what happens with Flemeth, but honestly I don't need to see her again.

I'd like to see Maevaris. Everyone else that we've already met can either be dead or have no reason to leave the South. I'd prefer to meet a new character than to force an unnecessary arc or appearance on familiar characters that don't need to be there.

He could be part of a side quest that only triggers if he's around or something. I'd like to know whether he found someone to teach him to control his dreamer stuff or not.

Oh right, I forgot all about that, thanks! That's good, though I'd still like to see him again 

none, it seems weird that some random dude is always in the right part of the world at the right time.

If the game ends up taking place in Tevinter these are returning characters I can possibly see returning:

Dorian (well, that's a must really if we are in Tevinter)
Sten (if he's alive and Arishok)
Harding (okay, I just think she's cute as a button and it's not that implausible)
Solas (mostly for story reasons, he should at the very least be mentioned)
Fenris (I'm thinking it's possible to meet him as he's hunting slavers, or as an escaped slave if you were heartless enough to give him back to Danarius)
Calpernia (I never got a chance to meet her in my canon play-through, but I really liked her and want to see more of her)
Varania (would be interesting to see what happened to her if she returned to Tevinter)
Gatt (not unlikely to see him as an elven spy for the Qunari)
Danarius (if alive I guess it's very possible to see him... although I would think it more poetic if Fenris still ended up killing him)


And for new characters:

Maevaris Tilani
Archon Radonis
Marius
The Black Divine

I suspect as returning characters:

Solas
Dorian
Maevaris
Stenishok
Vaea
Aaron
Tessa
Marius
Charter
Lace
Tallis
The Inquisitor(hopefully as the protagonist)
Maybe the other companions from past games

Her actions in Mark of the Assassin are what allow her to get back in the Qun's good graces by retrieving the list of agents. But even if she is somehow Tal-Vashoth I can see her showing up to help us in some capacity. 

While that is true it is notr confirmed to be the same Tallis, I think with how they worded Saarath's note that the devs are referencing it to being her, for example him saying Elf-Who-Is-Tallis to the first part about conflicting feelings matching Tallis. 
It wouldn't make sense perhaps, but it could still happen. For example Dorian's actions in DAI didn't make sense, but he still did them. Not saying that she will become a companion or anything like that(I wouldn't mind if she did since I liked her character, but if we are getting a dual-weilding dagger rogue female elf it seems Vaea is the more likely candidate) but I can see her having some role. Especially since this game seems to be having the Qun-Tevinter War being one of the main plots so I imagine all the big characters we met in the past connected to Tevinter or the Qun playing some sort of role.
