Is there a book or something that details the cities of the Auran Empire.
Capital of the Borderlands heavily details one major city in the Auran Empire, with some crib notes for a few of its subsidiaries.
The Patreon has a great article on Siadanos, a Class IV city in the borderlands, but aside from the references on the maps and scattered around the Primer and now Judges Journal etc there’s not an in depth list.
Unless Archon has gone through the entire Empire in his copious free time!
