The Ylfaen Empire was composed of four large cities and several hundreds of small and medium-sized cities. Some small and medium-sized cities was surrounded by lush forests scaling from five hectares to 20 hectares. In these forests, small to medium-sized beasts reside. In comparison, the scale of the forest that surrounded each of the four large cities ranges from 60 to 100 hectares. These forests had far more dangerous small to giant-sized beasts.
Some medium and small cities were connected with only a giant wall to separate each other. Those surrounded by forests were connected by a main road.
Aeren Town was part of Meliora and was located close to the border. The next town, Yuhl, was at least 30 miles away and was close to Valin Fort, a medium-sized city where on of its train was directly connected to Starhorn.
