I personally would be incredibly disappointed if Solas was the next villain, as I've said before. It's predictable and his story has far more possibility if opened up as a knowledge front. One of the last true sources of elven history.
@Shaftell: I think he holds spirits in such high regard because based on their foundation (wisdom, valour, etc) they are pure and predictable. He holds spirits in the fade in very high regard because they're untainted.
So, hopefully Solas, one of my favourite of the companions, doesn't end up being a very predictable villain which would cheapen his character and its writing IMO. He is highly complex and I can only hope that the after credits scene existed to confuse and mislead players, rather than introduce us to the next antagonist because, I just don't see Solas as an evil character.
Same - I think it's because of what we've been told regarding the Gods.
Solas calls Morrigan out for reciting the lores of the Gods (that everyone seem to know) while he gives them a different lore.
Plus - Mythal. Everyone seemed convinced that Mythal was one of the sealed gods yet we find out that Mythal had been murdered and that Fen'Harel had nothing to do with her murder. Or that Fen'Harel was not the trickster - he was the god of rebellion.
This makes me really curious to what is really going on here. And it makes me question if Fen'Harel/Solas was really the one who sealed away the Gods (even though he says they were not Gods - not in the way the Elves believed them - but he can say that considering he was one of them and probably doesn't seem himself as a God).
I just wonder if Fen'Harel is really someone they should be worried about or if someone had set up Fen'Harel to be the 'distraction', hiding the true motives behind him so we cannot see what we are supposed to be seeing.
For the Fade/Veil - it could be that Fen'Harel set it up or it could be that someone else did (Mythal?)?
The quest to activate the orbs was a way to tell when a new rift would appear - even the elf you meet in Hinterland (to start the quest) tells you of the orbs (I got a new update to Inquisition last night so I will see if this quest has been fixed).
I don't think Solas will be a bad guy in the next game but someone who is searching for answers. He tells a romanced Lavellan that it is something he needs to do. Cole saying that she is real means they all must be real is a good point. This is a guy who had been asleep for who knows how long then woke up to see the world was worse off - to him - and he needs to fix it.
For Lavellan to be real to him - it means everything around him is real. It could be he is just hoping that it is one big nightmare but since we don't get a lot of insight into Solas (or him dodging questions by using the Fade to explain things) we truly don't really know who Solas is - other than the fact that his relationship with Lavellan gives him a complete different card than you get when you don't romance him - showing that the relationship had impacted him in a way that none of us know yet.
Plus - I'm all for dragging Solas back and keeping him away from the Old Gods because you can pick up a codex in the Fade that says that 'they are angry and they will be freed' (need to check the codex for full information). The Inquisitor says the Red Lyrium are warm and Cole says they are 'Angry' plus it was around a whole lot longer than the Blight...
I'm taking a stab in the dark here and going to say that the Red Lyrium probably belongs to the Old Gods still sealed away and it would be very bad if Solas was to try and free them (so tempt him with whatever we can tempt him with and get his ass back to Skyhold where it's probably safer.)
And the ending should be interesting because he does have Mythal's soul/power - is it a good chance he has the ability to command the Inquisitor if they drank from the well? Because mine does and my Lavellan would fight Solas if he is intended to become the 'bad guy' in the next game.
She didn't freaking go out of her way to try and prevent this kind of chaos only for her boyfriend to start things up again.
