What would you like to see in Tevinter?

I just want to see a living breathing functioning imperium. I hope there's some dispassion in their portrayal rather than preachy reformism.

I want to be a blood mage and see the game recognize me as one. It shouldn't be hard because Tevinter.

I thought Denerim was a disappointment, too, to be honest. It's supposed to be this huge hub of commerce and you've got... like four people hawking their wares.

I'd love it if Minrathous - or Vyrantium, or Qarinus - was basically Vintish Frostbite-beautiful Kirkwall with no loading screens. You move seamlessly from district to district. Ancient, crumbling buildings held together by magic... slums that put Dust Town to shame... give it to meeeee.

Thanks for the clarification mate!
I wonder if the site of Andraste's death is known or has the site been "forgotten" over the centuries.

I don't think anyone disputes that she died up in Minrathous or that she was burned at the stake. The reason for the latter was probably not simply a desire to be cruel but also to prevent the likelihood of her body being occupied/resurrected by a spirit. Tevinter must have known such things were possible, certainly the former, and would want to avoid a demon using her persona against them. So you burn her to ashes, not much scope for anyone believing in her return there. For all we know, Hessarian could have stabbed her because he was afraid she wasn't dying.

What is open to question is where exactly in Minrathous the execution took place. The Chant places it outside the gates in front of the opposing armies. That seems to have been disproved by the historians as utter rubbish since her army never reached the gates of Minrathous, so the alternative suggested by Genitivi, the public square inside the walls, seems far more likely.

What does seem to have been altered over time is the site of the Valarian Fields. This is now shown up near Minrathous as indicated in the Chant. However, Andraste was captured from her stronghold in Nevarra and it seems highly unlikely that she would have got as far as the gates of Minrathous, only to turn around and march hundreds of miles back down south again. Both historical accounts and the Canticle of Shartan suggest that the battle was fought in the south of Tevinter proper, somewhere between what is now Nevarra and Val Dorma. Following the battle, Andraste was eager to march on northwards into the heart of Tevinter but Maferath realised it had been a near run thing in the previous battle and they in fact had yet to take on the might of the true Magisterium, whilst Tevinter loyalists were already rallying in areas they had previously conquered, so he decided to call time on the Exalted March and consolidate their gains in the south. Naturally Hessarian was only too pleased to agree to the proposal to surrender Andraste in return for ceding the southern Imperium to Maferath, because Tevinter was finding it increasingly hard to control even before Andraste began her crusade. So each side avoided spending valuable resources on a fruitless enterprise and Andraste was handed over. A thoroughly political decision.

I'd like to see the reformists at odds with the Imperium traditionalists. But I hope the slave owners and blood mages less mustache twirly than Lanarius, Erimond, or Howe.

I'd rather they were dispassionate, and in some cases, the slave owners preachy, a la Fassbender in 12 Years a Slave.

Yes and its a bigger issue in say Tevinter and Anderfels than it is in Orlais (mostly, and until Descent) and Ferelden (until recent surprise Blight).

Its not exactly like Orzammar and the Deep Roads, sure, but they're much more mindful of the threat than the south is/was.

If DA4 doesn't have a lot of Darkspawn, I'd be disappointed but hope for a Darkspawn focused expansion. If DA4 has zero Darkspawn, I'd be much more confused and dismayed than when there was (practically) no Desire Demons in DAI. There'd have to be a fantastic excuse and a promise of a huge focus on them coming (in DLC or a DA5), at the very least.

Really want to see what is in the forest of Arlathan.
Especially poignant for any Elven PC's.

Yes, I would like to see such, but I'd also like the exact opposite.  Societies are not monolithic; it's an entire spectrum from good to bad.  Everything presented thus far has been from the South's perspective...probably just a tad biased.
