Questions about Mythal (Inquisition/Trespasser Spoilers Ahead)

The general story seems to be that the evanuris killed Mythal. But a part of her--a wisp--still managed to live on and claw through the ages until it was willingly possessed by Flemeth.

But as for what happened at the end-credits scene with Solas....no one is sure. The general consensus is that Solas absorbed "an essence of Mythal's power" but we are not sure if that means he gained her soul, a part of her soul, or just something else. We also don't know what she put inside the eluvian.

And as for believing not believing whatever Solas says, that is mainly up to you.

Thanks for the reply! I completely forgot that Flemeth put something in the eluvian, so that's just another layer to the mystery.

My Inquisitor believes Solas, or wants to believe him anyway, but as a player I'm not so sure he's telling the truth. He is the trickster god, after all, and he didn't tell the Inquisitor about his encounter with Mythal. He also flat out refuses to answer all of the Inquisitor's questions, so he's definitely withholding information. I'm just not sure if he actually lied to her or not. It'll be interesting to see how that all plays out in DA4.

In DA2 Flemeth got Hawke to take an amulet with a piece of her in it to Kirkwall as an insurance in case she was killed by Morrigan/Warden. When she is revived on her own altar (although we didn't know it at the time), and Hawke questions how she could be in the amulet, she remarks that bodies are such limiting things and implies that it is perfectly possible for her to be still surviving in more than one place. This could well explain what is going on with Solas in the epilogue.

When we are threatened by the approach of Corypheus in the Temple of Mythal, a watery looking figure rises out of where the Well was located and protects us. Presumably this was an aspect of Mythal too, which makes sense since Mythal is said to have been born of the sea and thus has strong connections with water. This water spirit then leaves through the eluvian and presumably locates the rest of Mythal. So it could be this most basic aspect of Mythal that she places in the eluvian at the end, or simply a piece of her "soul" like she did with the amulet. Whatever the case, from previous history it is clear that Flemeth/Mythal always has a contingency plan, so it seems highly unlikely that Mythal is gone or wholly absorbed by Solas but her vessel of Flemeth is likely abandoned. Nevertheless, should Flemeth pop up again, it will not be an entire surprise.

Solas is quite right that the Evanuris seem difficult to kill permanently and it is likely because of this split soul attribute. After all it was the spirits in the Well that enable the understanding of how Corypheus managed to cheat death and Solas also says that he never imagined that a Tevinter Magister would have discovered the secret of effective immortality. Mythal's wisp stayed hanging around in the Fade, still remembering her identity likely because there was another part of her still secreted somewhere in the world. So the trick to killing them is likely finding the missing pieces. So when Fen'Harel declared they were as mortal as he, he was making the point to his followers that they could be killed provided you found the key to their defence against death. It wasn't inherent immortality but magically manipulated immortality.

When talking about immortality in relation to the other elves, what he means is the lack of aging, so before the Veil the elves never grew old. Solas has endured to the present by entering Uthenera (a sort of hibernation). Since he is stuck on this side of the Veil, presumably he is affected by aging the same as the other elves, both ancient and modern, so the clock is ticking for him to complete his plan or re-enter Uthenera.

It would also appear from a conversation you can get at the Crossroads with Morrigan (provided certain conditions are met) that the eluvian network is slowly breaking down through its lack of connection to the Fade. This may also mean that it is going to be increasingly difficult for the ancient elves to maintain their existence through uthenera, so if that is the case, it could be why Solas seems to think the only means of survival for them is for him to remove the Veil. Neither he nor any of the ancient ones consider modern elves to be true elves, even though they must be descended from ancestors who decided to accept the new reality and perpetuate themselves by breeding offspring, instead of simply waiting for someone to come along and put things back to how they were before. After so many generations away from their origins, this has led to a different appearance (hair, varied skin tone,etc) even though they do still seem to have a magical signature to their blood, unlike standard humans.

At present it is not clear exactly how Solas intends saving his People from the affects of dropping the Veil, but from what he says to Lavellan, modern elves are going to die along with the other races when his plan comes to fruition.
