Road to Metropolis
Welcome to the land of plenty.
There is a sort of grandeur in the reinforced concrete of the great wall around Metropolis. Designed to keep the goblinized of the region from entering the newly formed megacity; the wall was also used as a casement for a bullet train that connects the outlying regions. The bullet train is connected by frequent subway connections from the inner circle of Metropolis to the outer ring of the wall, called the spokes.
