Quiz How well (really) do you know Guardians of the Lost Cities? Hardcord version

Warning! Spoiler alert! If you haven't read all the Guardians of the Lost Cities books, firstly, quit this quiz, and secondly, run out and buy them.
Please note! The illustrations in the questions are very important. If Keefe or Jensi appear, answer the question "wrong". Otherwise, answer normally.
All the best!
