So... can I get your opinions on where the Forgotten Ones stood in the times of Arlathan? There seems to be a consensus that the Creators generally ruled things, so where do Amaris and Co. come in? Are they equals in a separate kingdom? Are they a subversive group? Are they even elves at all?
I have a pet theory that Fen'harel acted as a go-between for the pantheon and a rebel group of "gods". Then both sides start destroying Arlathan, Mythal gets murdered, and Fen'harel throws an epic bitchfit and locks both groups away. Then he takes a nap.
I think the Dalish worship of Fen'harel must be very complicated. They probably resent him for locking away their other gods. They most certainly fear his power. I wonder if they're grateful he sealed the forgotten ones away (they don't sound very pleasant according to dalish myth)? I also wonder if they have prayers to him, as conceivably he's the only god left free to ACT on their prayers (and thus bring about any kind of result).
The Dalish honor Fen'Harel, in their own way. Gaider talked about this a bit: "You have to remember that the Dalish honor Fen’Harel just as they do the rest of the elven pantheon — they simply do so differently. Statues/shrines to the other elven gods would be found within the clan’s camp, while a statue of Fen’Harel would be placed outside the camp, facing away. There’s no point in lugging around that statue with them if it wasn’t still a way of honoring him.
"Work backwards, and you’ll see a version of that in the Dales when the elves still ruled there. Monuments to Fen’Harel would still exist, and would be far more common outside of the settlements than within them."
According to Merrill, the Dalish don't really know all the facts - who was right, who was wrong, or even who started the war. It's hard to say what many might think about the Forgotten Ones, because they're a bit of an enigma. Merrill says, "Long ago, there were two clans of gods: the Forgotten Ones and that of the People. The Forgotten Ones preyed upon us. And one god who was neither: Fen'Harel, the Dread Wolf. He was kin to the Creators, and in the old days helped them in their endless war against the Forgotten Ones."
Interestingly, Merrill admits the Dalish don't know why the Creators and the Forgotten Ones were fighting, as well as how they don't know all their names. "No one knows. We barely even remember all their names, let alone who struck the first blow, or who was wrong. Fen'Harel was clever: he could walk among both clans of gods without fear, and both believed he was one of them. He went to each side and told them the other had forged a terrible weapon: a blade that would end the war. He told the Creators it was forged in the heavens, and the Forgotten Ones that it was hidden in the abyss. And when the gods went seeking it, he sealed them both in their realms forever."
Given some of the revelations from Inquisition, I wonder if the Forgotten Ones were opposed to the status quo of Elvhenan? It might explain why both felt that Solas was one of them, if he was akin to something of a 'double agent' and could walk among both of them - the rulers, and those who wanted to usurp them. When Solas does triumphantly return, I hope Lavellan can gleam some more information about Arlathan and Elvhenan.
