Really, really impressed with the epilogue reveal of who Solas was, the more I think about it. I've played every Bioware game and I'm impressed they can still blindside me like this.
All along, the story emphasised how Elven legends contained elements of truth, but had been mangled just like the story of how Arlathan fell (not to shemlen, but infighting). And suddenly, little pieces starting to click into place. Solas, the Dread Wolf, was somehow indeed responsible for banishing the Elven Gods (whatever they were) as the legends claimed. But it was something he did not intend, or later regretted, and was spending the entire game trying to undo this mistake.
Thus, the manipulation of Corpyheus and the Inquisitor to undo this mess and resurrect/recreate/un-banish these Elven Gods seems to be the true cause of the events of Dragon Age Inquisition.
Having awoken weak (perhaps through that hibernation Ancient Elves had access to), Solas gave the Orb to Corpyheus to respark. When the Temple of Sacred Ashes was destroyed and the Breach opened in the Prologue, Solas had then gone to join the Inquisition to nudge events back on course. And then a whole bunch started making sense.
Why, for example, Solas talked about restoring Elvhenan but seemed totally blase about the plight of the Elves themselves (even being taken aback when my Inquisitor apologising about not supporting Briala's coup at the palace with "why would I consider them my people").
Why his greatest fear, according to the graveyard in the Fade, was "dying alone".
Why he has this conversation with Cole;
Cole: They are not gone so long as you remember them.
Solas: I know.
Cole: But you could let them go.
Solas: I know that as well.
Cole: You didn't do it to be right. You did it to save them.
Inquisitor: Solas, what is Cole talking about?
Solas: A mistake. One of many made by a much younger elf who was certain he knew everything.
Cole: You weren't wrong, though.
Solas: Thank you, Cole.
or this one;
Cole: He hurts, an old pain from before, when everything sang the same.
Cole: You're real, and it means everyone could be real. It changes everything, but it can't.
Cole: They sleep, masked in a mirror, hiding, hurting, and to wake them... (gasps) Where did it go?
Solas: I apologize, Cole. That is not a pain you can heal.
Why he knew how to find Skyhold so quickly, a sight for the Ancient Elves.
Why he asked Varic out of the blue once if Dwarves had legends about "trickster gods".
Assuming I'm correct about any or all of this, pretty excited to see where Bioware takes this in future games/DLC.
