I love this idea and I have a few ideas if your up to it. 1. Regardless what path you take the Thalmor is attacking your religion so whatever the final battle is it has to be epic. a small band of warriors vs a large force. sprinkle in a little returning of Talos as a city lay in sige. maybe finding another Dova. 2. Having the city be underground and above ground would be spot on after all they live in a time of war. what would be better to defend. 3. As far as Ulfric, his stance on Talos always felt more political then anything. I think creating a retreat for real worship is easily justified. 4. The Stendarr faction has a hall in a vast field with nothing around... maybe giants but easily relocated. could be a spot to look at. 5. Just cause i wanted a fifth thingy I dig the idea of this project and i would be happy to help
