HorrorFell is a Combination AU, a mix between Horrortale and Underfell. HorrorFell is an AU where a neutral run was done in UnderFell, and is far into the future. Due to a lack of resources- mainly food- and strict laws put in place by Queen Undyne, the majority of the monsters have slowly gone insane, including Sans and Papyrus- though Sans still holds a small measure of his former self, but given that former self was nearly as violent, this hardly means much.

Another human child, named Aliza, with a violet soul representing Fear, has fallen into the Underground. However, she has no guide in this violent, brutal land, as Flowey has long since perished.
