Mythal could have come from the fade, I agree with you. That would mean Elgar'nan wasn't a part of the fade at the point she met him. Supposedly he was created when the sun and land met; that could be metaphoric for him becoming flesh from spirit, or sentient. The question is what the sun, land and sea represents. I'm guessing: sea is the fade, land is the earth, sun is = something inside the fade (mosaic), of which the moon is supposed to reflect? The way they work together would answer some questions.
That canticle has me wondering whether it was really the Maker talking to Andraste. I don't know about him; Solas does say he's "open to new ideas" regarding the Maker, so apparently the idea didn't exist in Arlathan at least.
I imagine the moon might be a metaphor for the Golden City.
Yeah I know I'm pulling this one from nowhere
, but we had the Sun which seems to be a natural part of the world , something powerful.
In the Dalish tale (and let's face it , part of it is probably very wrong but that's all we have for the birth of the elven people/civilization), the only thing created is the moon by Mythal.
You can say the Golden City is a pale imitation of the Sun , yes it's shiny ... in the fade it's always there ,just like the Sun was supposed to be always there before Elgar'nan threw him into the abyss.
I said this earlier but there is a raw fade , all dark rock , lyrium veins (I imagine Titans/earth ) and it's always night and there is just a ribbon of light left , and the Golden CIty now Black also always there.
It could be something that did happen because in ..I can't remember in which DA book I read that , but anyway it is written in theory you could find in the Fade , the origins of the world .
And that dark vision in the raw Fade , or memory ..well it sounds like what happened with Elgar'nan and Mythal , in the tales all went dark."With the sun gone, the world was covered in shadow, and all that remained in the sky were the reminders of Elgar'nan's battle with his father—drops of the sun's lifeblood, which twinkled and shimmered in the darkness"
So did the Elves created the Golden City as a pale imitation , if the city was golden in the raw fade perhaps things would look better?
About the Maker = the elven sun deity , well reading the Chant of Light with what Trespasser hints at...elves being spirits..the brain starts to melt.
Whatever the sun was for the elves , they beat him into submission .
I think there's a Golden mosaic of Elgar'nan holding the sun down.So they would have a different history with whatever the Sun is...they also went after the Titans unafraid ...
But whoever or whatever was talking with Andraste , well the fade does offer reincarnation to spirits , although the abyss part is creepy as hell.And Elgar'nan did threw the sun in the abyss....
