From Delgar

Aarnbreg is the capital city of Henge, the easternmost province of the Araxian Empire, located on a large island just off the coast of Delun. It is a hub of cold water fishing (chiefly mussels, crab, cod, halibut, perch, and candlefish) due to its proximity to the ocean as well as Lake Elgen, the second largest lake in the known world, and of course the Aarn river which gives the city its name.

Aarnbreg is well known as a site of pilgrimage and refuge for the aethersick, as it is the place where the Skeld was first discovered and has since become a distinctive part of Hengian culture.
