Hey, do you know about the city we're living in?

Nebulia City is located next to a really huge wall. That wall is red-brown colored as a brick. The surface is clear and there isn't any scratch on it. Also, the wall isn't only big, but also very long that you can't see the end of it. Until today, no one arounds you ever say that they've seen the both end of the wall. Anyway, you still can see the top end, fortunately. The height is the same as the tallest building in the city. For one reason, no one dares to climb the wall, neither to search for it's end. It's just there effortlessly, maybe even before the history of this city began. Some say, climbing the wall brings bad omen. Do you believe in such tale?

Oh, enough about the wall. Now about our city. Our city was built next to that huge wall, and our city is very-very big, although it is located in the middle of nowhere. Surrounding our city is a forest, mountain, hill, huge river that leads to the city. The nearest city is located very far from here. Strange, isn't it?

Even so, our city has quite advanced technology. You can see vehicles roams the road, ships roams the river that leads to the sea. You can go into shops, mall, or even amusement park. Everything is complete in this city.

Only, every coin has two sides. This city, despite of the urban and the legend, also has the mystery and the dark side. The dark side that makes you shiver. The night life and the criminals, which mostly located near the wall itself. The world by the wall, is the world for those of lowly class and those of dark history of the city.

Even so, all of you... still a citizen of this city, right?

Lately, many strange things often happen in our city. You known, when night arrives, the street lights will suddenly dims and die. Or a person can die eaten by his own graffiti. Then, a secret door by the wall. The only door that leads to the other side of the wall, will open it's seal and lead the way to the other side. No one still knows where does the door lead us. Even us.

By the time the door opened, the time will stopped by itself, and it will become a very long night. For those ordinary people, that time doesn't exist and the night will pass like usual, but for some people... they have the power, to stay and survive the long night... also to enter the world of the other side.

It seems that tonight, the door would open once again.

Who knows what people will do tonight?
