The Slenderman is a creature that is around 8-9 feet tall, has long arms and weighs almost nothing. He originated in Sweden and steals the souls of people, mostly children. To adults, the Slenderman smells like rot and decay, but to children, he smells like buttered popcorn. The Slenderman will inhabit a well near the house or school it's victim goes to and it will often stalk them for years at a time.
There is a signature on the Declaration of Independance that reads "S.Lendermann". This signature can also be found on The Magna Carta.
