Summary: Maximalist dreampunk weird fiction city-state creator for enculturating your character.
Please feel free to add your own ideas and results in the comments.
I have created four city-states using this process. Their full descriptions can be found near the bottom of this post along with commentary.
I've now added increasingly extensive adventure hooks for each of them.
Here are brief characterizations:
Wander in the summery woods of Eidesia and follow the rivers. You will be channeled into the well-watered City of Masters whose greatest artworks become possessed by Delphic naiads.
Visit Vatrium, the Peace Offering, sky-sarcophagus of the Reist dead. This fatal flock is tended by the city’s existentialist monks. Death is coming to this peaceful place, and not merely in the form of corpses.
The Spies of Liminumia own almost nothing and can destroy almost anything. They cut down and harvest whole civilizations over the course of generations.
Theoseveria - The Radiant Death-Vaults of the Dukes Judicial.
Also see the following cities in the comments:
Saxherm, Solomon VK’s patrician underworld in the hills.
Setroxia, Dan Sullivan’s dark shrine of the poppy, and his city of Attar, boomtown of scent, its people stratified by aroma and violence
Sarabande, Ben Massey’s sacrificial city of hard hearts, hard loins and harder rule.
