In a new plane...
Spheros is the city you are living in. It is one of the three cities of Celestia. Spheros, Apreago and Nova Azur. Spheros is the most influential city of the three housing 6 of the 10 most powerful non-humans.
It was the first of the cities to be founded. It was run by a couple, one angel and one demon who ruled with an iron fist. A long time ago they were assassinated to make way for a parliament which is the base of the council. Spheros also governs the villages and towns near by when approached by the leaders of them.
Places in main Spheros are much like a human city with houses, a square, the auction house. There is a market for interesting artifacts. All paid for in souls.
