Fade text
- WE ARE HERE
- WE HAVE WAITED
- WE HAVE SLEPT
- WE ARE SUNDERED
- WE ARE CRIPPLED
- WE ARE POLLUTED
- WE ENDURE
- WE WAIT
- WE HAVE FOUND THE DREAMS AGAIN
- WE WILL AWAKEN
It's pretty clear to me that this is referencing the old gods. Notice that it says they are sundered and crippled before mentioning their pollution, which to me suggests that they're in a weakened state from being put to sleep in the first place. My guess is that they mean they're separated from the taint, their god mojo. Even though polluted suggests not a normal state, it's not something we can really assume.
Anyway despite the truth of that, the next interesting big is that they're still enduring and waiting after all that, and that they've "Found the Dreams again," and that they will awaken. Well, they're already polluted, referring to the archdemons who have woken up. That suggests and hints to me that one, they aren't talking about the dreams of those they control or who they worship, but the fade. And two, they're not fully "woken" when tainted and this might not be what they're talking about. It gives importance to all of them needing to be awaken. We. Which is interesting for how divided old gods supposedly were.
What I think this means is that Solas, sealed them away because even in their slumber, they couldn't die, and he needed their bodies to act as pillars to hold the world away from the fade. Based on this text:

The workers mentioned in the text, running around soulless, that is what points to Darkspawn and what suggests the old gods. The spheres merging at the end suggests the old god's deaths may be necessary as a step for our world to converge with the fade.
I think that if the old gods are "killed", possibly even if not tainted first, then their souls we thought destroyed will still find a way to reassemble themselves in the fade.
There is a little more helping this idea that the old gods aren't necessarily a separate entity, or weren't all the time:

This suggests a few possible things. The first to me is that it's possible that Ghilan'nain was actually one allied with the old gods, the forgotten ones even though we still know her name and legend. It would explain why Mythal still didn't show him favor in the end, and the god of beauty is an actual old god, the last one we killed. But what also makes me believe that is the description at the bottom:
For one moment there is an image of a shifting, shadowy mass with blazing eyes, whose form may be one or many. Then it fades.
See where I'm going with this? The taint acts as a sort of hive mind to all infected. If the old gods all have the taint as their old god mojo, what happens when multiple archdemons are around? I think this suggests that the old gods are indeed a part of something greater and bigger, and killing them is just helping them return to that state at full power, while Morrigan's ritual, likely an elven ritual, serves to keep their souls here.
And remember, that elves helped to develop the Warden joining ritual with information left over from Arlathan in the first blight. So that adds to this idea in general really, that it's all tied with elves, as always, lol.
And even if Ghilan'nain isn't an old god, that man was obviously tricked, much like Tevinter was into having the nerve to "fly high amongst the gods." Very old goddy indeed.
One way or another, Solas' reaction suggests the grey wardens are ****** up somehow. It could just be the pillar explanation, but what he said also to Blackwall about if he was sure killing them would stop the blights, that to me is a good supporting conversation to this as well.
And whether or not people think this is likely, one should consider this pic:

Notice that the song ceased being something in their heads, but an independent and literally audible sound, so loud that it shook the earth around them. If true, then it suggests the old gods do wish to be tainted. Because they are confirmed to actively be calling out.
That concludes the theory. The Grey Wardens are fools as always, and assume that the old god's souls are "cancelled out". But they never stopped to ask themselves... why the hell would that be the case, rather than both souls simply merging and going to the fade?
