To those of you who have not read or even heard of the book up there in the topic title, nor indeed seen the TV miniseries or the live-action play it spawned, here's what you need to know about the world set up in Neverwhere:
There are two layers of society in the world, one of which goes completely and literally unseen and unheard by those "normal" people who live on the surface. Beneath the oldest and most culturally or historically significant cities you can find, there are parallel civilizations made up of strange beings whose existence you'll only remember until you look away from them, and who have influenced the crafting of our world right down to the very names of our subway stations. They live in our sewers and abandoned subway stations, as well as places they built long before the city up above existed, and sometimes just in plain sight of everyone on the surface.
These beings come with a staggering variety of stories, each as strange and nonsensical as the next. Why, in London Below alone, you can find tribes of homeless who can speak with and worship the rats that travel up on the surface, telekinetic mercenaries whose personal flairs make pro wrestlers look refined, old storybook figures such as the Marquis de Carabas, two ancient gentlemen assassins who burned Rome and are quicker than sight, an imprisoned angel, the Earl of Earlscourt Station, the friars of Blackfriar station, and countless others.
This RP will not be going to London Below, however, and the challenges faced there by a young Scottish businessman, a girl with a murdered family, and a cunning cat-lover will have no importance here. No, this RP will be set in Paris Below, with a whole new set of locations and characters that require no more knowledge of the original novel than what I just posted up there.
So, if you happen to be interested in a bit of a faux-modern dark fantasy with influences from both fairy tales (the original, twisted versions) and various other forms of fantasy, drop a post, and don't be afraid to ask for any details or clarifications you need.
IMPORTANT NOTE: For those of you concerned, this is NOT just another RP where people in the modern world have magical powers or whatever. Neverwhere had very little to do with the surface world outside of stuff that had to do with the main character (since he was from there), and I don't plan for this story it involve it very much, if at all. Consider it not a modern fantasy, but a fantasy where modern stuff might be happening somewhere else unrelated.
