Isidis is the largest town and the capitol of Green 12. As the youngest and smallest of the greens, Isidis is largely autonomous and does not pay tithes directly to the Church, nor does it fall directly under the military might of Green 1. There is a small cathedral to the Holy Mother in the city, and the cardinal there is a member of the ruling committee.
Day-to-day governance of the town is left to a mayor, and the affairs of the green are overseen by a committee made up of members from the Church, the Enginseers Guild, and the Traveler’s Guild. All of these members work in, and reside in, the town of Isidis.
