Hall of Infinite Doors

You scramble down the hill and onto the patch of ground. The campsite is bare except for a fire. You do immediately notice, however, a gigantic skull, looking almost human, sitting beside the smoking embers. It was probably used as a seat. As you move forward to examine the skull, you notice, at the corner of your eye, a small knife. It is lying in the bones a bit away from the camp. You walk over and pick it up. It is without a sheath and quite simple looking, but it will surely prove useful. You put it in your pocket.

Suddenly the ground shakes. Bones rattle and slide together and you crouch low to the ground in an attempt to steady yourself. Then, a massive, gutteral roar reaches your ears, and you glance over to your right to see what terrible monster made the noise. You quiver (and not just because of the earthquake) in fear as you see an enormous, long black shape slither its way through the mounds and mounds of bones. A mighty hiss startles you and you fall onto your butt.

You pray that the horrible creature has not seen you.
