Edit: Wait, Zathrian was immortal, wasn't he? But that was a curse? It's so hard to keep track of all of this.
Didn't Zathrian kind of do the same thing with Witherfang as Corry did with the dragon. Not completely though since he could be killed, but the curse/ his essense in witherfang was what keept him linving for so long past his lifespan. (?)
Solas just doesn't seen the kind of crazy/odd that Flemeth/Mythal is. However, that could also be a result of being murdered or being forced to inhabit a human body.
Actually, I think that's just Flemeth how's crazy (funny) not Mythal.
... THIS WEEK ON LIFETIME - "THE SLOW ARROW"
Mythal, hiding her slowly growing infection, continues her love affair but the other party remains a mystery. Are they a man or are they a woman? Or NEITHER?
June is busy crafting a red crystalline blade on his anvil. Could it be.. THE MURDER KNIFE? Will he be the one to pull the dagger or will he pass off the dirty work to another, more emotionally compromised "family" member?
Elgar'nan drowns his suspicions in elven gladiator fights and wine. But how long will this peace before the storm last?
Sylaise builds a pyre of wooden carvings depicting the accomplishments of the rest of the pantheon and watches it BURN TO THE GROUND. How much longer will she tolerate being second best?
Ghilal'nain visits Andruil in Elven God hospital and weeps over her twisted form, her tears spilling onto Andruil's hand.. which twitches at the contact. Will she reawaken!?
Meanwhile, in the same hospital several floors above, obtaining access under a false identity, Dirthamen visits the bloodied remains of his barely breathing twin soul brother Falon'Din. But what is the purpose of this visit? Are there other allegiances at work? Has he decided that death would be a kinder fate for his infected brother?
Fen'Harel visits the slaves quarters of Arlathan and their plight brings him to tears. But these tears are HOT. HOT WITH FURY at what the other Gods believe it is their right to inflict on those they consider beneath them.
WHO WILL WIELD THE MURDER KNIFE? WHAT TRAGEDY WILL BEFALL THEM NEXT? ONE THING IS FOR CERTAIN.. IT'LL ALL BEGINS IN.. "THE FAMILY."
REMEMBER - THIS TUESDAY at 9PM. THE SLOW ARROW. You'll never see the tears coming before they hit you.
This made me laught out load, almost falling of my chair. 
The way the red lyrium is growing everywhere (Emprise du Lion especially!) makes me feel like a catastrophy about to happen. What's the link between it and Corypheus anyway? We know he's cultivating it through people in the future we can be sent to, but to what end? Is he using the lyrium... or is the lyrium somehow using him? It all comes back to the Blight and its origin I think. In any case, I'm more afraid of the Red Lyrium than I ever was of Corypheus. It seems to be growing exponentially, and nowhere in DA:I do we come across any way of stopping it.
During Varric's quest we get to know that Lyrium actually is alive, since it can become blighted. And in earlier games its referred to as waters of the fade, and tears of the maker but the codex says its a metal.
The way Solas talked about it seems to be somethinghe'd well familiar with, however. So maybe its more connected to the old Gods.
A question just beacuse it popped into my head; Does Solas voice his opinion on the Maker? If so I can't remember it. I know however that he dennounces the old elven Gods. He belives that they excisted but not that they were Gods. Maybe there's something to that? Maybe they just were really inflencal people during the old times. Take for instance ME3, you find out that the asari godess was nothing but a protheon (don't remember the correct spelling), helping the people to evolve faster... Just a thought.
