11. Cairo, Egypt
12. Wyvern, Scotland

13. Norway

*I'm not sure who I should give credit for the Xanadu bit to (Aris?) but this isn't one I'd have any idea about the exact location otherwise so apologies to whoever it was.

(And incidentally, responding to your point that Elisa used her thumb to count 'three' on her hand: I count using my thumb too. Sorry this is irrelevant, but it wasn't worth wasting a post over IMO).
