God of the Subways
The skeleton of the city’s public transport system is the metro. All the metro lines meet in a set of tunnels underneath the city centre. These tunnels are gloomy and dark and something of a fire hazard, since they are cramped enough that if one train breaks down inside the tunnel, the trains behind it are stuck until it can be moved out of the way.
According to some stories, these tunnels are the domain of the god Metron. It is not known where Metron holds court, but you can sometimes catch glimpses of him and his followers on the platforms of the abandoned station a couple of minutes in from the western entrance to the tunnel. Sometimes these platforms are brightly lit, catching your eye when they burst out of the darkness as your train is passing. Then you can spot strange shapes on the walls and platforms that must belong to the ever-changing advertising boards, or so you convince yourself.
