A war between nations is not a civil war, so yes, I did refer to the squabble over the throne business. I don't know if you've noticed this before, but reports of destruction spread quite easily. There is no way that all of Ferelden could have been ignorant of the incoming Blight, given numerous reports of destruction.
As for the elves, yes, they were in bad shape. That still doesn't explain why the idiot who started the curse led them back into the forest in the first place, though that might have just been out of his own vanity. Also, why don't the werewolves just wipe the elves out? Yes, the forest spirit has something against that, but there is literally no opposition to the beasts!
Uhm, then how the hell did that dragon get down there? Or for that matter, how could the dwarfs not have known about the broodmother (or the delightful porn of it)? And don't forget, you actually see a bloody army of darkspawn marching down there. Man, those dwarfs must be really good at fightin' them darkspawn considering how much attention they pay to them.
Ooh wait, I've got another one: where the hell did the mage faction that summoned the sloth demon come from? I played as a mage, and I did not hear of any such organization when I started in the tower. Or did they just form after my amazing betrayal of my supposed best friend? I'm sure they were all awestruck by his masterful use of the emo I'm-cutting-myself-and-sprinkle-things-with-blood magic. But whatever, I don't exactly expect coherence from Bioware games, or fantasy stories in particular. I just enjoy poking holes into them while playing the game, basically the same approach I take with SyFy original movies.
