I'd really like to see an inner-conflicted villain, one doing it for the right reasons, specifically this guy:
I think that's the way the game should point. I think that given the events of DAI, your next incarnation is slotted for having Urthemiel's soul.
The devs are tired of Southern Thedas, so I won't be surprised if it takes place in Tevinter or Qun territory, or somewhere else entirely. Maybe the Anderfels, as events seem to point North or West.
I have a theory that has only been bolstered by DAI that the Elven Gods and the Old Gods are one and the same. More spoilers abound:
There are seven Old Gods, and Nine elven Gods. Solas states in random dialogue that he thinks both the Elven Gods and Old Gods truly existed, but were not divine. He of course, knows this to be true because he is one of those Elven Gods. We also know that the Elven Gods were warring with one another, enslaving their worshippers and conscripting them to fight, and that was the true cause of their collapse. We all know from Corypheus, Flemeth, etc. that powerful mages can put part of the spirits in other things/beings.
Perhaps instead of picking sides like all the other gods, the Trickster with his love of rebellion and hatred for slavery turned all of the Elven Gods into the Dragons that Tevinter worships, sealing most of their potency away beyond the Fade. This would explain Cole's cryptic "they're still trapped behind the mirrors" remark to Solas. Solas and Mythal were not trapped, so that explains the 7 Old Gods. The Old Gods then taught humans magic, as in Tevinter lore. It could also explain why Solas hates Grey Wardens -- they are killing his family, the Old Gods, and he also does not believe killing all of the Arch Demons will end the Blight. From his random talks with Blackwall, he seems to think the Blights will go on or get worse if the Old Gods are slain.
My big question is what spurred Corypheus into the Fade in the first place, and what really caused the blight? Solas seems to be surprised the Blight exists. It's unclear, but I speculate that Solas may have given Corypheus his elven orb way back before the First Blight, trying to bring the Elven Gods back to save his People, perhaps before falling asleep for centuries. This could have allowed the first humans into the Fade in the flesh. I mean, how did Corypheus get in the Fade in the first place?
