The moment Solas’ ritual went wrong and the Veil was raised, can you imagine the total chaos? He tore the Fade away from the physical world and forced magic behind a barrier that had never existed before. That act alone would’ve changed everything - spirits, magic, minds, and how the Fade itself worked from that moment on.
Been thinking a lot on this the last couple of days. Ancient elves had lived with constant contact with the Fade. Spirits existed with everyone and the Fade was woven into the world naturally. When the Veil went up, that connection was severed all at once. The vast majority of living minds (elves) would’ve suddenly vanished behind a barrier spirits couldn’t cross safely enough. Elgar’nan destroyed an emotion, the spirits tied to it died so I think we can apply the same logic here. Remove the source abruptly, and logically many spirits wouldn’t have survived. Others would break or twist immediately and the violence of that moment would’ve been overwhelming, not just physically but psychologically - for both elves and spirits.
The Fade itself would’ve been completely destabilised. If spirits and the Fade reflect the world, then at that moment it would’ve been reflecting shock, pain, fear, and destruction with nothing holding it together. I imagine it like a kind of big bang - like a violent rearrangement of the world.
Solas was damaged by this too. His regret memories show cracks running through his body, and Matt Rhodes’ art shows blood being pulled from him during the ritual. This nearly killed Solas. Like other ancient elves, Solas was made of both the physical world and the Fade - so the Veil didn’t just break the world - it tore through him as well. (Me noting the blood being pulled from him and wondering if that’s what went wrong and why he gets trapped in Fade Prison eventually - because his own blood is tied to it).
So then Solas falls into uthenera.
I don’t think this starts as dreaming for him. I think he goes into full on blackout mode at first. That doesn’t mean he wasn’t affected by what was happening. Even without awareness, the chaos of that time could still have been absorbed by him subconsiously.
The closest comparison I can think of when thinking of Solas in uthenera during this early time is being underwater in an ocean during a violent storm. You wouldn’t see the waves, but the water itself would be violent and disorienting. You wouldn’t need to be fully conscious to be affected by that.
Over time, things would begin to settle. Elves who survived the fallout regroup. Spirits adjusted as best they could to the new reality. The Fade continued to reflect the world, but now in a completely different way.
But all the while, Solas is drifting. For a long time, I don’t think he was conscious in any meaningful sense. As centuries passed and his sense of self slowly stabilised, I think his awareness would come and go. He wouldn’t always understand what he was seeing as his mind, spirit, and body weren’t yet aligned.
Perhaps this is where the fables and legends of him patrolling the Fade come from - Solas drifting through the Fade as his awareness faded in and out - perhaps he didn’t even have control over his mental form in the Fade leading to more fearful depictions of him such as ’Fen'Harel, the Dread Wolf, gleefully patrols the Beyond to feast upon the souls of the dead’.
As the physical world of Thedas changed, then it makes sense that the Fade would change with it. Humans and new generations of elves spread, other races - and their fears and beliefs and ways of thinking began to affect and shape the Fade. Solas would have been carried along that process, even if he wasn’t fully aware of it.
I think over long stretches of time, he became more conscious. As his mind wandered the Fade and he himself stabilised more, he began to understand what had happened while he slept. He would’ve started encountering others from his time, like Felassan (and I imagine they were searching for him as well, across those long centuries), and started learning about history. But the Fade wouldn’t have been the one he remembered. When he finally does wake he wakes into a system that works differently. And in my opinion, he had to re-learn how to navigate it.
“As I slept, spirits of the Fade showed me glimpses of wonders I had never imagined… I learned how to defend myself… I learned how to control my dreams with full consciousness.”
“Glimpses of wonders I had never imagined” isn’t how you talk about a place you already know well. It’s how you talk about something that’s changed enough to present something Solas never experienced before. When he says “I learned,” I think he means that literally.
While he hides behind the façade of his experience being of “the Fade” to conceal his identity, I do believe he genuinely had to relearn it’s navigation. The veil changed the rules so to speak. I don’t imagine learning to defend himself in the Fade was his default before the Veil - but after? Most likely. And he had to learn how to control his dreams in order to move within the Fade at all. Which is also why he makes the comment about blood magic. In this new reality he’s come to learn blood magic weakens his connection to the Fade. Why would he use such magic at that point if he’s only awake a year before joining the Inquisition? He loves the Fade and needs to access it.
Can you imagine the different states of mind Solas must have passed through during uthenera, and then what it was like to wake physically into modern-day Thedas for the first time? His “birth” into the world? How fractured that “beginning” must have been for him, and how much it would have affected the way he understood the world and his desperation to fix his mistake.
