Allen lives in Woodsboro California, a homicide serial killer that only kills when his mother gives him missions, which is to extract vengeance based on their client's wishes. Sometimes he visits his mother in Purgatory and often spends most of his time in the human realm. It was never revealed to Allen whom his father is, only with the information that his father works under an eldritch entity called "Slenderman". Likewise it's never clear if his mother's name "L" actually stands for Lucifer.
