I got a little speculation here. Hear
me out for a second, what I got may be rubbish, but it's something.
Assuming these Archdemons are the Old Gods of Tevinter, then what if
what kills the Archdemons is nothing like what we think it is? Perhaps,
if you do Morrigan's Dark Ritual it simply pulls the soul apart form the
taint, then pulls the soul out of the Archdemon, and in fact THAT is
waht kills the Archdemon, the soul escapes through what WOULD be a
mortal wound. By this process, it wouldn't matter who killed it, because
there's no tainted soul to transfer once it dies.
Now, if you
DON'T do the ritual, what if it's the taint that corrupted the Old God,
that transfers to the Warden that kills it, the taint overwhelms
him/her, and they die, but the soul of the Old God survives. By THIS
process, EVEN IF the Warden sacrifices his/herself to kill the
Archdemon, Morrigan performs the ritual off on her own, or with some
random man, and it still pulls the soul of the Old God right to her.
It's not like they can quantify a soul in the DA universe, so the death
of the Warden may not be due to the souls destroying eachother.
I liked reading this speculation. Cool idea, but unfortunately, its been almost proven that the matter is soul-related by the Awakening expansion. There is a point in the Silverite Mine, where you find one of the Architect's experiments that seems to focus on soul transfer.
Actually...
Now that I think about it, this theory means that the darkspawn HAVE no soul since according to the Warden theory and the experiment in Awakening, when a soul enters a contained body, both souls extinguish themselves... so does this mean Flemeth's false grimoire really was just a complete ploy?

Haven't they returned to Thedas already? I killed several during Origins already.
Also I do know that ASOIAF is a reference, but ripping off the "Magic returns when the dragons return" that blatantly...
Magic returns when dragons returns is something that the OP made up. Dragons were never extinct. There was a period of several decades where there were no dragon sightings, but also thousands of years where dragons were 'common' and Thedas was just like we see it in the games.
It was actually over 200 years. They were said to be wiped out over the course of the Steel age, the 6th age with Dragon being the 9th. That's a very long time to not have a single sighting of even hunting drakes and female dragons searching for lairs. Then two rampages happen at once right at the turn of the century and they start showing up everywhere. Kind of odd...
And to the OP - there is no "Truth" here. It's all speculation and theories. Don't go claiming such things, even passively.
Lore speculation is fun, though! 
@Bayz: Backlash basically sums up the history of draconic life on Thedas, so I suggest you read that post I have quoted above. I never said magic "returns" with dragons, but since you bring it up... if the old gods are dragons, and they taught it to the imperium, we probably will see their strength in magic in the upcoming story. As for a "return of magic" like ASOIAF, that would be just silly. Magic is already present in Thedas, and the idea of magic coming back is already present, as a war with the Chantry has erupted at the end of DA:2, which will probably weaken Orlais and coax the Tevinter into attacking them. With the fall of the circle, apostates will run rampant and dabble in many more dark arts than previously. The Tevninter has already been described as regaining much of their former power, but they do not rule over Thedas as they once did. If they swing for conquering Thedas, its like throwing gass on a flash-point house fire. Magic itself would become a driving force in the events to come, and with the Tevinter back, I think that suggests to the idea of the old wars and the quote "Magic will come back- all of it" as well as "everything will be as it was".
@Backlash93: Yes, this was completely speculative, but I was writing a persuasive argument. Any essay written in a persuasive style is meant to present your ideas as fact. I was not writing a paper by scientific method based on a correlational study where I have to choose my words carefully to express objectivity. This is a subjective post, and the best way to argue it persuasively is call it truth. This allows others to pop in, and express their counter-arguments and beliefs from a stronger standpoint, because I basically coax them into response by using a strong bias.

On another note, someone above wrote a theory about the fade and the real world colliding, as if the veil were to fall. That is DEFINITELY and interesting take on the "skies will part" quote. The quote itself is very figurative, as if to express a major epiphany.
