And then maybe the Tevinter protagonist of the next game can beat some sense into him.
The next game really needs to do justice to the Tevinter magisters and not show them as twerps being stomped on by Solas. We've been hearing about them throughout the games. Till now they were the epitome of evil who caused all that is wrong in the world. Now it turns out most of it was done by elves and dwarves. high time that the knife ears get their comeuppance. 
But seriously I've been reading the bit in World of Thedas Vol 2 about how the Archon of Tevinter faces off against all the seven priests of the Old Gods after they get tainted and that man sounds badass. So it's not as if the Tevenes are all noise and no substance (looking at you Venetori). Really hope they actually show it by making a pure magic build really amazing in DA4.
Archon Hessarian? Ya, he's alright.
His house was in ruins when he was young, rose in power to become the Archon, possibly faced off against the Seven and won, held Tevinter together during the First Blight, led Tevinter against the armies of the Maker, slew the Maker's prophet, pulled a major social upheaval by slaying the elite Altus houses and changed the state religion while rearranging social institutions, and during all this he remained Archon and kept Tevinter together to lead it from its darkest period to a new Golden Age. He is now an Anointed (saint) in both Chantries.
But, y'know, he was just another name in the history books of Thedas.
Still, there are many magisters we've been introduced to with varying opinions and beliefs, from the codex entries, comics, and in game references.
I'm hoping to meet the (Black) Divine. A guy who publicly assassinates a magister at a party, leaves before the victim's friends rally, and remains the spiritual leader of the Imperium sounds like a charming fellow.
