Treno

There is no existent middle class in Treno, instead, all of its inhabitants are either extremely wealthy or extremely poor. The rich nobles live down on the waterfront, while the poor live up in the slums around the city. Treno is known as the Dark City due to the perpetual state of darkness in which it remains. Fortified on all sides by impenetrable walls, navigating the city means braving the heights of such walls and bridges in the dark of the city's seemingly endless nights, although an alternative is to travel by boat across the water that the bridges cross.
Treno is home to a Card Stadium used for Tetra Master tournaments, Doctor Tot's residence, and an Auction House. It is also one of the locations linked by Gargan Roo.
