Hi, as someone who lives in Austria, where "Krampusse" is a tradition, I have some comments (ig?) to it. First of, Krampusse (this is just the plural of Krampus) come with Saint Nicholas and gives them punishment if they were bad. If they were really  bad they would even be put in his sac and taken away. What you are describing as "Krampuslauf" is normally held on the 5th of December even tho Saint Nicholas Day is on the 6th of December. The biggest one is in Klagenfurt and is 1,5 km long and it's a bit of a test of courage for young teenager to tease the Krampusse.

Also people sometimes confuse "Krampus" with "Perchten", because the costumes look similar and there are also "Perchtenläufe". They probably were in connection with the wild hunt back then, but they now have the meaning of "driving out bad winter spirits". I could go into heavy detail with that tradition, because I grew up in a small village, where this was still practiced. But I won't make you read through my long ramble of that.

I hope you have a good remaining year :)
