there was this guy a few days ago that said something about a Romanian location
usually this would just be passed off as fan speculation, but he said something about “seeing it at work”
so i looked up the Carpathian Mountains (located in Romania), saw that Bran Castle was located in the mountains, and noticed the similarities to the place Diana is in in the H3 Announce Trailer
the Romania location is almost guaranteed, i feel like… maybe this is it
