Looking at Cole's little cryptic comments is interesting. I think quite a few them directly refer to Solas.
1. "He did not want a body, but she asked him to come. He left a scar when he burned her off his face."
I think this one might be referring to him, if you accept that the ancient elves or whatever could transition from spirit form to a mortal form, which there is a lot of evidence for. The way I read it is Mythal asked him to join her on the earth, in a mortal form. In mortal form, he had Mythal's vallaslin, which he "burned off his face", perhaps even by her instruction. This could have been the start of Mythal doing something to move against the Evanuris, which is maybe what turned them against her.
2. "Bare-faced but free, frolicking, fighting, fierce. He wants to give wisdom, not orders."
This one seems like a continuation of the first one, almost. At this point he's bare-faced and free, and has become a somewhat reluctant rebellion leader.
3. "He broke the dreams to stop the old dreams from waking. The wolf chews its leg off to escape the trap."
And then this one I guess could be referring to him lifting the Veil, what with breaking the dreams to stop the old dreams from waking (the Evanuris?). The wolf chewing its leg off to escape the trap could be describing him somehow cutting himself off in some way to avoid the same fate.
I don't know if any of this contradicts other elven lore really, but I feel like a lot of them refer to Solas. Unless they're just references to other media I don't know about.
