The surname of one of Germany's most important families. Like Farmer or Smith, the name is derived from the process of actual fartknocking, which was used in Germanic warfare throughout the 19th century and up until WWII, when the Fartknocker family wouldn't allow their heritage to be sullied by association with the Nazi party. It involves torture through sulfur emissions done in close proximity to the enemies olifactory senses.
