I prefer 2e, so you are correct, Spec.
Ryan, Slenderman (NOT Slender) is a figure recently created on a paranormal thread that I cannot remember the name to. Slenderman is a tall figure between 6 to 10 feet tall, pale as a ghost, NO facial features or hair, arms that are about as long as his body, and usually wears a black suit with a red or black tie. He is well known to stalk people and make them disappear without any trace left. In medieval times, Slenderman was called "Der Grossman" (as it would be pronounced). If anything, Slenderman is a modern monster with classic horror monster traits. (I've done ALOT of research into him.) He is the subject of many video series, while the most well known is "Marble Hornets." He even has a few indie games out where you must evade him and collect items while he stalks you.
So, a small adventure featuring Slenderman would be a great idea.
