NEON SUBWAY WARS
Atop Neon Street, shining lights keep the city alive and awake 24/7. Beneath it, the lights don’t shine so bright, or so often. Not due to any shortage, but because shadows lurk, and they want it that way.
The literal underworld is something between a lawless land and a fractured territory, split into many turfs. 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, while urban transport has widely moved to the surface with autonomous and flying vehicles. Only shady folk dwell in the underground.
Despite their antique status, the underground rails still hold some interest for Neon Street, and they wouldn’t give it up for good. The Police Force performs operations in the metro area whenever it is in the interest of the hyper wealthy pulling the strings, and a few elite cops make sure the underground gangs do no harm. When it comes to the less fortunate, there’s no such support, but a vigilante tries to keep an eye out for them.
Overall, the constant tug of war in the underground is just another move by Jeff Musk, who could wipe them out, but profits from the lack of subways and by selling weapons to the warring gangs.
