People think that the underworld is a fiery hell hole where all the bad people go, well those facts are not true. Well it is a hell hole, but it's not on fire or anything like that. The truth is the underworld is a mirror image of the overworld where humans live, but in the underworld is where all killers reside. We may know a few like Laughing Jack, Slenderman and yes even Jeff, but where do you think they learned their instincts to kill? Residing in the underworld is a place known as Horror High where all the greats learned to stalk, kill and torture. It is where all beginner killers go to learn the proper ways in their line of work. In the overworld there is a legend of a well that connects the overworld to the underworld, but most humans believe it is just a silly legend well unfortunate for them it is not, truth of the matter it is the only connection to the overworld the underworlders have.
That's all i got but basically this is a high school where beginner killers learn the ways of the pros. I saw a skit on this and thought it would be cool so if anyones interested just post below. And to answer questions no theres no sons and daughters of killers, but i will allow apprentices.
