The Labyrinthine City

The Labyrinthine City is a place inside of America´s Shadow. It is possibly located along Route 60 in New Mexico but it as it doesn't actually exist in our world, it's possible that it can be in many places at once.

Description
The city is described to be huge, bigger than Los Angeles or New York and to consist of hundreds of thousands of skyscrapers sprawling out in all directions. Somewhere hidden in the labyrinth is a gate made of cold iron, the hunted can leave through that gate in case they can't find the way they entered.The master of the city cannot change, alter, or hide the gate, it is the only thing the master has no power over.

In the center of the labyrinth is a clock that shows how many hours the victim has, until the next hunt begins.

Monsters
The people in the city look normal at first glance, until the visitor looks at one of them for too long. In that case, their face caves in and turns into an endless tunnel lined with rows and rows of sharp teeth. "Almost like the mouth of a neverending lamprey eel." according to Dr. Ryder.

But the real monster in the city is The One Who Carries The Horn Of Bone, the master of the city. His face is not caving in like the ones of the other people in the city but it is not human either, and he carries a horn made of bone with him. He makes the rules in the city and controls the way it works.The rules in episode 04 - The City & The Labyrinth were the following:


 * 1) You hide. I seek.
 * 2) Find the Gateway - and you can leave
 * 3) No more outside help

The master of the labyrinth can change those rules whenever he wants but his powers have limitations: Everytime he creates a new rule and blows his horn, he can change the labyrinth but also weakens himself. Whether that is good or bad for the victim is unclear as their situation becomes more dangrous each time but the masters power also becomes weaker.

Trivia

 * According to Malcolm, it's not a real city that people live or work in but just a labyrinth instead.
