I got one question! Where did Bagadar go when he's out in Port Malan's Prison? The way to Freeport was blocked. Travelling by ship? Maybe.The Legionnaire outside of Freetown says the Zamohr Pass has become blocked and the Commander is still trying to keep it quiet, that suggests relatively recently. If it has been years since Adaon and Bagadar left Freeport that would tie-in.
That's not correct, I always get the amulet before Adaon quest (do it as last because he's useless for me) and he is still there.
