Grue

*You've felt like something is off all day long. You can't explain what it is, but something in your gut won't let you relax. You duck into the nearest public restroom to wash your face and try to get a grip. As you dry your face off, suddenly the lights in the bathroom go out. Glowing text appears on the mirror above the sink: "It's pitch black. You are about to be eaten by a grue." Suddenly you have the unmistakable feeling that something very large and very hungry is looming behind you.*
