About the Lady of the Skies, I also tend to think it was Mythal, giving a 'nudge' to history through Andraste. Also about the eye found everywhere in DAI,i would take it as a reference to Mythal too, if she is indeed the lady of the skies.
From Visus constellation codex:
On another note about the Tree of Peace:
Isnt Mythal's vallaslin like tree (i've read vines somewhere in the thread before, but it could look also like tree branches)? She was the voice of reason trying to keep the peace according to Solas between.."two factions" but murdered? Solas says her murder was like a final drop that made him decide to raise the Veil, without her keeping the balance/peace the world would come to be destroyed .
So "before the first stones of Skyhold were laid, the tree was cut down to serve as a war table". We know that Skyhold (aka where the sky is held back) was Solas' castle originally, and maybe where he raised the Veil. Could it be Skyhold was made after Mythal's murder as Solas started his work on his putting up the Veil? Tree of peace was cut down (Mythal no longer 'living', the living tree sybmol of piece is cut down) made into a massive war table, a symbolism for a war against all factions (massive war
) - aka Solas putting up the Veil, imprisoning both factions after her death.
And Skyhold has a depiction of Mythal when elevated during Cori fight, so again Mythal
One of Mythal symbol is a dead tree (leafless) although perhaps it was changed when she died .
But yeah it would also work for the war table .
The tree symbol is somewhat important for elves , but I don't think so far there's proof it goes beyond pure symbolism.
I mean in IRL norse mythology , there's Yggdrasil , the world tree.But nothing like this in DA , as far as I can remember.
Still there's Mythal symbol (and even in the Origins intro you can see a tree losing its leaveshttps://youtu.be/Q94rdV9M1M4?t=41), the tree cut down at Skyhold as a symbol of peace , the trees statues in the Crossroad , the Dalish plant a tree in the grave of their dead (Emerald graves) the city elves have the tree of the People :the Vhenadahl http://dragonage.wik..._of_the_People
In this codex , it seems some city elves believes the tree of the people was a symbol of Arlathan.

A couple of somewhat strange things found in the DA wiki ,in the Primeval Thaig , you could find a "Carved Ring of the Vhenadahl".
The Primeval Thaig is older than the Blight in theory so...the Vhenadahl may have been important for ancient elves ..
And also from some tablet found in Mythal temple (WOT2 page 201)
Tel'enara bellana bana'vhenadahl
We/it lost eternity or the ruined tree of the People.
It sounds a bit funny, no idea if an actual tree was ruined or it's just a metaphor for something else.Mythal murder , a peace treaty being broken if it's like Skyhold and the tree could have been a symbol of peace/ truce ...No idea.
