Skara Brae:
It's Shamino's home.
It's the spiritual center of Britannia. Literally.
It's focused on rangers and fishermen, the two best types of people.
It's been wiped out a few times, including "accidentally" by the town's alchemist, as well as sacrificed to destroy a lich.
It's laid out well, not too big, not too small, with a good variety of shops.
It's based on a
real location.
