Well, well, well! It seems that either I've come up with a stumper, or no one's following this series anymore...anyway, Unidentified Earth 20 has gone as yet unidentified, with only one guess offered. Tsk, tsk, tsk. I suppose I should offer a hint, so...it is in the Middle East.
Ah well, the show goes on; time for the next puzzler.
Where are we? Rot-13 your guesses, please!
