...they're in Britain? how did I not pick up on that until now

 

[Zinon]

I didn't quite expect Britain, there were many British vibes with Arthur and all, but some of the Arthur books come from France although those books from France could refer to Arthur as a British person I don't really know, but Britain being the setting is weird I don't know.
