Understand that I have spent countless hours on ALL of the Dragon Age games. They are, candidly, of superior quality, but the ending for Inquisitor leaves me wondering. First, the Inquisition has to go. It is too limiting, and the Inquisitor, now the Herald or whatever must move on. OK, I get it. But, consider the original ending to DAI.
1. Emperess Celene hangs on to her throne through her alliance with the Inquisition. Someone has conned her into trying to take it over. What makes the Inquisition work is the Inquisitor but he / she abandons it after Tresspasser. Too bad Celene. Your short stability is over.
2. Silence falls on the Grey Wardens and Hawke vanishes. Or does he / she? This plot thread is totally unresolved, and Hawke does show up at the ending of Tresspasser.
3. If your Warden survived and romanced Morrigan / Leliana he / she is off hunting for a cure for the taint. Now he / she returns at the end of Tresspasser. Is he / she cured? And why is the Warden running off to find a cure for him/herself anyway? Fiona was glad to be done with them, and given the massive chaos they were responsible for in the name of the greater good, I suspect that conservative Wardens will target this Warden.
4. During one of the background conversations in the war room they talk of rifts forming where the Inquisition cannot reach them. Interesting that Ferelden and Orlais decide now is the time to seize control of the Inquisition and end it. From what I could tell the only involvement F. had during DAI was to boot the mages out of Redcliff after its rulers let the mage / templar war play out in the country. Interesting what a poor king Alastair turned out to be. So, what happens when a new rift opens? Do they send Teagan to beg the Inquisitor to return? What do the people in Orlais and Ferelden think of them forcing the Herald out, and make no mistake about it, the Inquisitor will be gone. Even if they found the Inquisitor, why would he / she bother to help them. Let Celene and Alastair close the rifts.
5. Regardless of who the Divine is, members of the Chantry - dissidents if you will - will not tolerate a Herald of Andraste. If the Herald cannot be controlled by them, they will see the Herald "put out of the way" - ie., killed.
6. Iron Bull. I suspect that he is not dead no matter what they say. Consider, if you play the evil Warden in DAO with Wynne and Leliana in your company, both are killed. And yet, Wynne dies in the books and Leliana is back two games later. I suspect they could even bring Anders back.
So what is the next major event in Dragon Age? I suspect Tervinter with a whole lot of plot threads left hanging. I suspect the Inquisitor will be back, possibly as the Thumper of Tervinter or some such. Yet, for all the uncompleted threads, I will wait - impatiently mind you - but wait none the less.
