Can't read the whole thread because I'm still only to the first round of the meeting, but I thought Teagan's arguments were nonsense.
Caer Bronach was seized by bandits and the Inquisition annihilated them, took back the keep, and built it up. That was a service to Ferelden. Giving the keep back would be understandable and I would have liked the option to give it back, but for Teagan to then jump to baseless conclusions like all this indicating some kind of invasion, it's ridiculous. He draws an erroneous parallel to the Grey Wardens, when in fact it was Sophia Dryden (a relative of the Theirins) who attempted a coup, not an invasion. She was a native of Ferelden, and she was fighting a tyrant. The Grey Wardens officially severed all ties with her. And then he brings up the current alliance with the Grey Wardens as some kind of negative point.
Is Teagan forgetting that both the Hero of Ferelden and Alistair are Grey Wardens, and that either of them could possibly be king, or if female the Hero could be queen? Is he also forgetting that the Grey Wardens were granted Amaranthine? I mean, these accusations defy even Loghain's level of paranoia.
And then he refers to Gaspard ruing Orlais, when my worldstate had the three-way deadlock.
