So, here's a proper medieval Halloween figure, the Green Knight. Not
meant to be a horror story but have you heard it? A giant of a man, who
basically comes up to Arthur and his court, calls them sissy pants, and
asks if anyone would like to take an axe swing at his neck. Not without
price though, the Green Knight gets to return the favor in one year.
Normal people would be freaked out by someone who says "try to kill me,
it'll be fun!". Worst of all, is that after King Arthur's nephew Sir
Gawain steps up to the challenge beheading the Green Knight, the Green
Knight calmly picks up his severed head, holds it in spooky fashion, and
decrees, he'll see Gawain in a year. Creepy.
