Duron is a city-state on the world of Eamon located on a large island about six days' travel west-northwest of the coastal city of Dorier across the ocean. The journey from Dorier to Duron passes the smaller island of Wango.
Duron occupies the westernmost portion of its island behind a sharp lines of tall mountains that forms its eastern border and acts as a natural wall. The road into Duron from the eastern part of the island passes under the mountain through what was originally a natural set of caverns that the inhabitants enlarged and smoothed. The city itself is beautiful and its royal palace grand and lavish, with the city's harbor to the west.
