In my current replay of DAI, I went back to Val Royeaux after defeating Corypheus, and dialogue mentioning Mythal immediately caught my attention. So of course I ran to the internet and found the full exchange here on Tumblr, (credit to dalishious). So I wasn't imagining it.
It’s a conversation between a noble and his elven servant. The servant recalls that, as a child, he discovered ruins in the Arbor Wilds - ruins, that years later, people from Tevinter seek him out for. This is almost certainly the Temple of Mythal.
But the most fascinating part is the conclusion to this ongoing dialogue:
Noble: You're worrying Madame with your shouting during the night, not to mention the other servants.
Servant: I can't help it, sire. A woman comes to me in my dreams, and she whispers things...
Noble: You mustn't say that, not in public. People will think you'll be taken by a demon!
Servant: She's not a demon, sire. She says her name is Mythal, but... I will be quiet, I promise.
So this same elf - who discovered the Temple as a child - is later being visited by Mythal in his dreams. And did they discover the well and drink from it themselves, or is Mythal’s presense just generally strong in the Temple?
This has a few interesting implications:
Solas isn’t the only one who can visit/talk to people through their dreams; but how? Is it the Flemythal fragment? (possibly, considering Flemeth's dialogue about Mythal coming to her in the lonely dark).
If the Inquisitor drinks from the Well, it becomes easy to imagine that Mythal could communicate with them in a similar way.
This adds even more weight to Solas’ angry and desperate reaction if the Inquisitor drinks from the well.
There’s another interesting detail: by the end of this exchange, the servant - who is initially described as not having vallaslin - appears to later have one. (I didn’t catch it on my first pass, so I’ll need to go back and confirm whether it was always there or if it appears later when I saw it.)
Either way, it raises an interesting question. Was taking the vallaslin his own choice? Or was he influenced by Mythal? And what was Mythal whispering to him?
Noble: How odd that more men show up at the manor to speak with you. You, and not I.
Servant: I apologize, sire. I'd never met those men before.
Noble: And what did they need? Nothing unsavory, I hope.
Servant: They asked about ruins, something I found when I was a child. Rather strange they knew about it at all.
Servant: Sire, you should know those men approached me again.
Noble: Again? The last time they came to the manor, I told them to leave you be.
Servant: They came to me in the market. They claim I misdirected them, but I swear I didn't.
Noble: No need to worry. I'm your patron, not them. I won't bow to Tevinter scum, that's for certain!
Noble: How is it that you know anything about ruins?
Servant: You forget, sire. Before I became a servant at the palace, I was with one of the Dalish clans.
Noble: Ah, yes. I keep forgetting because you don't have those ridiculous markings on your face.
Servant: I was too young. Long ago as it was, I remember the Arbor Wilds as if it were yesterday.
