In Germany's black forest, before Christianity came to the place, they had a legend about creatures called tomtin. These were wholly evil little dwarf-like creatures, who wore red (the color of blood). They would band together, pull a traveler to the ground and beat him.

The tomtin had a leader, though. He was known as Nacht Rupert. Nacht Rupert would sometimes come into villages taking a small army of tomtin with him, and could sometimes be seen peering into windows. He would often kill those he was watching, unless the people inside were keeping to the old faiths, in which case he would give gifts.
Great music, history and fun! GSR!
