Nature itself, deserts, forests, rivers, jungle, coast, etc.
Main city in the forest I guess. Elves getting the best of the natural environment, buildings in communion with nature. Glass, jewels, gold, silver.
Some of us already posted some pictures on the Elves race discussion, 5/5, exclusiveness, sometimes I think it's redundant or devs aren't reading.
Minor cities can be less cocky, but still elegant.
