I know I'm wayyyy late to this. I work outta state for long periods and don't have time to do anything but whatever work Im in engaged in during my travels. So I just finished TME. So many avenues opened up that were not concluded. One of which.... Who is Felassan? He mentions too many one liners that open up heavy questions that go unanswered by the time the book is finished. I'll throw this out:
-Perhaps an ancient spirit/demon? Maybe an ancient elf who awoke from his last cycle of uthenara?
-There's a bit somewhere in the book when Felassan is rehearsing what the ancients did and what there culture was like. He refers to them as "we" and calls them "my people". Not anything really worth looking into until he poses the question: Do you know what I did back in my day son?.... or something to that affect.
-He mentions that Mihris wouldn't want to meet his clan. Perhaps fellow spirit/demons like Imshael? The two of them did have an obvious camaraderie. Who ever kills Felassan would have obviously been a leader type figure that he contacted via the fade. Definitely some spirit/demon implications there, or perhaps implications of the ancient elves who could speak to others through the fade as they were in the long sleep.
-Whats coming? What was he referring to just before Imshael departed Mihris' body that Imshael so easily understood through a very vague description of words. The Breech that will be in DAI maybe?
-Who do you think killed him in the fade during that last sentence? .... The Formless One, Imshael, a member of the Pantheon, Some unknown fade character at this point, an ancient Elven leader in uthenara, maybe one of the original Archons.... Flemeth? What do you think? Preferably with some sort of substantiation if you would.
-Last but not least, who does Briala remind him of? He didn't quite finish that sentence.
My guess: Felassan is a demon/spirit of sorts, who took the body of an ancient elf. Flemeth killed him. Disappointed that he passed up her chance to use the Eluvians (to help her get a hold of Morrigan, I mean right?). He was going to say, "she reminds me of Andraste". And yes, he bated Imshael to leave by letting him know that the breech was going down soon.
