OK, many peoples (me included) don't understand what happened at the end with Solas and Flemeth...
So Bioware we need more explanation, we want a DLC, we want an Extended cut...
Stop teasing us... Give us an explanation...
We don't want another little boy like in ME3 which didn't explain nothing about the why of the reapers... You did the same...
Shame on u Bioware, Stop teasing Us...
I want my ending, or i want an DLC quickly ...!!!
Come on, people. Why do you need everything spelled out??? *sigh* That's what drove me nuts about the ME3 ending sh*tstorm too. Think for yourself! The ME3 ending makes perfect sense if you think about it and actually listen to what everybody tells you throughout all three games... but let's not open that can of worms again.
The post credits scene is ambiguous on purpose too. I only finished the game a few days ago and haven't thought about it much yet. So I'm not at all sure yet what it means. Nor do I know if we're supposed to understand just yet since this is not the end of the series (unlike ME3).
My current idea is that Fen'harel is a truly TRAGIC character. Completely misunderstood by the Dalish and painted as a traitor while he actually wanted to SAVE them. And his final scene with Flemeth makes me wonder if he and Mythal were lovers once, at the very least they were very close friends. Another wicked irony of how wrong the Dalish got their own mythology/history. Throughout the game Solas is disgusted with slavery. And during his romance you learn that the Dalish got one more thing wrong: the vallaslin. I believe Fen'harel was horrified at the ancient elven slavery and wanted to get rid of it. Like Dorian, he wanted his society to change. He was a rebel who wanted a better society. So he locked the old "gods" away, thinking this would benefit his people. Then he woke only to realize that his actions had the opposite effect. He's consumed with guilt over his actions and also harbors a lot of anger at the present elven society that paints him as a traitor. He feels betrayed by THEM. He has a highly ambivalent relationship with modern elves in the game. That's why he's so hostile towards the Dalish but at the same time looks like a race supremacist. The Dalish are not his people, they are pathetic in his eyes. They don't know their own history, they got everything wrong, they run around with slave markings and feel proud of them. They are complete fools in his eyes. At the same time he knows it's his own fault the Dalish are this way. And it eats at him. He's torn between anger and guilt.
So he decides to undo the damage somehow by bringing back the old gods. He's desperate. So he turns to Corypheus. I still can't see the logic behind THAT tbh. That's just really dumb. But I guess any kind of help was welcome to a weakened Fen'harel. He wanted to correct his mistake NOW, so he had no other option. But again his plan was an ill-conceived one. But this time he realized his mistake in time and decided to stop Corypheus. He still wants to restore the world to what it was once, though. And there are many hints in the game that suggest that once there was no barrier between the mortal world and the spirit world. And it looks like Morrigan knows this and is plotting something along the same lines. She too wants to bring back the old gods but without the taint. Hence the tease from the inquisitor they should get a room. They are much alike! And why wouldn't they when she was raised my Fen'harel's dear friend Mythal... I hope Morrigan will be the true heroine of Thedas in the end, not a villain. I think she truly wants a world of magic but without any evil. So she's trying to create a better version of an old god with her son.
Then there's Sandal's prophecy that talks about all the magic returning. Which is exactly this. The old gods will return in some way, but we know that the gods were not exactly benevolent beings, which is why Fen'harel locked them away.
One might speculate that Fen'harel was the one who created the fade in the first place. Another realm where he could lock the old gods away. That's why he understands the fade so well. He created it and therefore knows how it works and what it is. I suspect that the creation of the fade drained the world of much of its magic and caused the ancient elves to lose their immortality and also all their power. The ancient elven gods (whatever they really are, perhaps only very powerful elves who are revered as gods now) reside in the Black City, which is Arlathan. The Tevinter Imperium invaded Arlathan and obtained the powerful magic of the ancient elves by which they were able to enslave the weakened elves. So Fen'harel "freed" the ancient elves from slavery only to leave them defenseless against new enslavement. (The elven history is so wickedly ironic, it's brilliant!)
Immortality is linked to great magical power to me. Merging the mortal world and the spirit world would then not only bring back the old gods but also immortality for everyone. Considering that the fade in many ways represents corruption because it harbors very angry gods and angry spirits, the plan to unleash all this sounds like a very dangerous idea...
I guess this is why Fen'harel realized that the world is not ready for it yet. His wish to dissolve the veil was a hasty one.
Fen'harel's main objective is still to restore the ancient elves to their former glory though. Without the slavery, of course. And I think he is willing to make great sacrifices to achieve his goal. He's not unsympathetic to other races but the elves are still his priority. His anger is an issue that might turn him into a villain in the end. Especially now that he and Mythal have merged. Mythal wants revenge for her betrayal and murder. I believe they both had the same goal once. Maybe they worked together to help their people? Maybe her murder gave Fen'harel all the more reason to want the old gods punished/locked away. But now Mythal is more concerned about revenge. Fen'harel wants more than revenge, he wants a better world. Mythal does too but her judgment is more clouded than his by anger. So those two are a bit at odds now perhaps. They aren't antagonists though.
My guess is that Flemeth gives herself to the Dread Wolf to be absorbed so he can help their people. It pains him greatly obviously that she is the one who has to make this sacrifice even though he is the one who should take the punishment for his foolishness. That's what he feels sorry about imo. They silently agree on their union. As Flemeth says, nothing can be forced upon the unwilling. So she is very willing to get absorbed into Solas' body. Mythal may simply feel sorry this has turned out so bad for their people. And that he's in so much pain over it and has to "kill" her now. Or it's more cryptic. She obviously sent something through the eluvian. Probably a part of Mythal. So she might be apologizing for her future betrayal... I can't tell yet.
The mural of the wolf and the stabbed dragon might suggest that Fen'harel betrayed Mythal. But I don't read the final scene that way at all. It seems very tender to me. It might just symbolize his guilt over having to kill Flemeth in order to fulfill his plan... he might feel like he betrayed her even though she did it voluntarily.
Now that he has "killed" her, the mythology is suddenly true after all in a away... it comes full circle in that scene. And yet, it's still not for the reasons the Dalish believe.
