El Dorado

El Dorado (エル・ドラード) is the country ruled by Demon Lord Leon Cromwell, located on another continent larger than Australia on earth.

It is wide and has towns divided into districts. Forest, Field, Lake, River, and Mountain districts. Every sector is protected via a magic circle. An artificially created land of nature and tranquility–a magic city. That is the land of Demon Lord Leon Cromwell–El Dorado.
