Another one I just thought of - If you save Duke Ravengard you should be able to turn Wyrm's Rock back to ally status, especially if you sneak up and just kill Gortash instead of fighting everyone. The previous leader revoking his endorsement of a corrupt ruler should have some weight on the city.
There's also the old guy who refuses to leave his cell in Wyrm's rock. I was always so curious about him. I literally killed the guards and made the way out easy, and he just decides to sit there? At least tell me why.
