"How does Solas figure into all of this?
If you’ve seen the ending, you know Solas is a special circumstance. I’m not going to promise that he rejoins the party and things are great, but he will make an appearance. I know people are excited about that. Solas remains an exceedingly complicated and enmeshed character in the world. In the course of the DLC, we’re not going to wrap up his storyline – that’s just way too complicated. But we can add a lot of texture and information to it, so it isn’t just this one note of confusion. Instead, it’s an opportunity to learn more about his situation in a way that we may be able to explore in future games. If there are future games.
So, Solas is a factor, but the epilogue isn’t about him?
I would say no. You will certainly come away with a greater understanding of his situation by playing Trespasser, but it’s not just the Solas story. Instead, this is one where the crisis, the regrouping, a last hurrah, a chance to see your friends and followers, and Solas are all a part of it. Seeing how things turned out for Solas is just as much a part of the adventure as seeing how things turned out for Blackwall – it’s just that his plays out differently from the others."
