From the introduction:
Krampus, often referred to as the Christmas Demon, has many legends attached to him, varying wildly from one region to the next. The most common version of this vile creature is that he’s a satyr-like being who unleashes upon errant children sadistic and severe punishments that often include death.
In this free mini-supplement, we will draw upon numerous sources of folklore to create a version of Krampus that truly embodies Lovecraftian horror. This version can easily be modified for your own needs, using ours as a basis from which to work.
