I'm currently setting up to run Second Darkness 3: The Armageddon Echo. A lot of it takes place at an old Elven city. Elven architecture in general features a lot of curves and non-concentric circles which stands in stark contrast to Drow architecture that features a lot of irregular curves. I want to emphasize this with any additional encounters I add to the city.
Can anyone refer me to additional resources beyond Second Darkness 3,4,5 and the Elven City Map Pack for instances of these architectural styles? I'm ready, willing and able to modify maps to add war damage and the like. Just looking for additional map references.
