The literal underworld is something between a lawless land and a fractured territory. Among them, there’s the Dark Neon Clan, a group formerly known as yakuza, and Joe’s Bricks, a group of outlaws led by Joe, whose dwarven ancestors lived and mined in the underground. Each of them rules over an expanse of rails with their own metros. The Police Force performs operations in the metro area whenever it is in the interest of the hyper-wealthy pulling the strings. When it comes to the less fortunate, there’s no such support, but a vigilante tries to keep an eye out for them.
