This one was a little difficult because very little information is available on the topic. There's a lot of speculation and may even be straight up false information given here. There's no official lore, as far as I know. At the end of the day it's just a silly youtube video so should be taken with a grain of salt, or Swadian butter.

I use audio from different sources but they are taken out of context to create something new. Credits to where credits are due. No copyright infringement is intended.
