Oberonian City for People Playground

A city located in the caverns of the moon Oberon, orbiting around Uranus. Monotone buildings, catwalks and glowing billboards go as far as the eye can see, and the city is never quiet. There's always the constant sound of bustling Oberonians going about their days, or nights, the hum of fluorescent billboards and the rumble of monorails.

This contraption is part of a faction known as the Republic of Oberon, which is part of a worldbuilding project I'm doing with multiple other creators.
