Bear with me here. I only started playing DA games a couple months ago, so still a huge special interest for me.
Perspective is such an interesting part of these games, and I love how they juxtapose that against current events and characters' personal goals/needs.
Let's say you're the bodyguard of someone you really respect. You fail in your job to protect. You're doing your damnedest to save people who need to be free. You're a freedom fighter, because you care, deeply.
Your protectee is murdered, but you survived. I would imagine this would be something that could piss you off.
You imprison the perpetrators in the only way you can.
Then because it was such a big magical undertaking, you pass out and slip into uthenera for thousands of years.
You wake up, a bit groggy, find out how weak you are (which, to someone who has never been lessened in power is awful) possibly panic a little and fuck up.
You see you fucked up, while dealing with some pretty massive mental illness issues (PTSD, Depression, anxiety, survivor-complex) just for starters).
The entire world feels like a bad dream. Like it felt for people seeing the alternate future.
Humanity, a species you last remember as 'beings setting up tents in mud, selling bone beads, who stank a lot' have somehow flourished and enslaved the very people (or the descendants of your people?) you gave so much to free.
I don't see how, given that, at the beginning of the game Solas could honestly feel any different.
It'd be like waking up and finding out some sort of creature you thought of as vermin (sorry human lovers, perspective here) was running the world and harming your grandkids.
And worse, because of how you imprisoned the murderers, it actually tore the world you were trying to save apart, dooming said grandkids.
Except, familiarity can breed caring as well as contempt. He learns over time, as he's repairing his strength and healing his mind, that these 'tranquils' are still actually people. If romanced, you even fall in love with one of them!
Aaaand, you're probably also (originally) a wisdom spirit with any spirit's ability to demonize. Into Pride in his particular case.
It's a miracle he's not even more stand-offish with people.
Pride can blind us to a lot of things. In many established world religions, pride is bad. It's a deadly sin in xtian mythology.
And Solas is both wisdom and pride. Two sides of the same coin.
It's warped into his very being.
His character growth arc from who he is at the beginning of the game, to who he is at the end is so well written.
I hope Dreadwolf continues his growth arc in some way. I really love growth arcs. He might even have a redemption arc.
I think it's utterly delicious when authors play with perspective like this. It's really well done with Solas.
I only wish I felt more of the other characters were as well written so I could analyze them, too. But honestly, most of them really aren't well characterized. On a professional level, I'd send them back to the author with a gentle suggestion that they do some more character development & much needed writing for them.
Note that I base all my analyses on the base game and DLCs. I haven't managed to afford the books yet. (Being poor sucks.) So there could easily be information I don't have access to. And wasn't there a show? Was that any good? (I struggle with passive entertainment like tv shows.)
