Chapter 1- The Game Begins

It was a dark, hellish type of night, filled with a type of mystery. The lights were bright, glowing on the street that lead to the small little town of Greeneville, Tennessee. Sam Winchester snorted, his head tossing to the side as he was fast asleep. Dean, his older brother, just gave him a small smile, keeping his eyes on the road. There was no one. Absolutely no one, except a few cars here and there. Kids up to no good.

How they ended up in Tennessee was beyond his comprehension. The images of the small little children that were killed still reels in his mind, and Dean almost throws up his lunch. He had been to Hell, but he could not, he repeated, COULD NOT stomach that.

"I won the game." was engraved in the arms of the little children as a small reminder of whatever serial killer that did this was still on the hunt. It gave him chills. God, did it give him chills.

They pull off to a parking lot of a local motel, Dean nodding off slowly. He had enough energy, however, to check them in, knocking Sammy awake and then crashing on the beds. Not comfortable at all, but he'd been through worse.

And what they woke to set their investigation off immediately.

The room was blurry at first, then Dean shook his head to wake himself up. He found himself facing the ripped, rusted wall with scribbles that made out, "WELCOME TO THE GAME." in dark ink. Sam awoke with a start, and the Winchester brothers found themselves facing the same writing.

"The game?" Sam asked groggily.

"The game." Dean replied.

And instead of a period, the sentence was ended in a circle, crossed out with an X.
