You and your friends decided to go on a camping trip. once you finally got everything set up, you needed to go to the bathroom so you went off into the woods, after you finished you started to head back but along the way back a weird fog hit. It was hard to see anything as you were walking back, you ran into a tall figure, that was inhumanly thin it had long tentacles that came from its back and long, lanky arms. It stood a good distance from you but close enough to where you could see it.
