So I found this last night, one of a number of easter eggs that seem to be hidden in the game. It was an ‘accident’ site.
From what I could gather, a witch was riding her broom at high speed when she suffered a bird strike, forcing her to make an (unsuccessful) crash landing in the field where I found her. I had actually been waiting to see more evidence of witches in the game, as I had noticed a few ‘distinctly unchristian’ sites containing wooden fetishes and other signs of corruption. Didn’t quite expect it to take such a funny turn though…
Actually, I’d love to see some (non magical) witch questline content in a DLC. Atmospheric horror would work very well in this game.
