Agoneie is a city bordering Masuul with a big lake to their north.
It takes care of a lot of the trade between the two countries, but is known to be pretty lean with its punishments whenever something illegal is discovered.
It both acts as a border patrolling city and as a bridge between the two cultures making it somewhat hard for the capital to control but also an advantageous asset to have, which makes the city close to self-governing.
