Solution to #6: Déjà Vu
The visual clues in this puzzle use various concepts from past puzzles in the Quest:
1. No Map (draw the letter)
2. Celcius Code (bacon cipher with hot and cold colours)
3. Roll Call (dots and the number label on the phone)
4. Clock (important date in history)
5. Alchemist's Code (finding a letter through indexing into the symbol's name)
6. The Types You Choose Are Key (using keyboards to find a letter)
7. How Do I Know My Young Brothers (a musical note)
8. The Letter (atomic weight, converted to a character)
Next, one must arrange the clues in the order in which they appeared in the quest:
1. P: drawing the letter
2. X:bacon cipher BABAB
3. V:receiver label=8, 3 dots
4. W,D:Refers to Haultain's birth year, 1925
5. F: The alchemical symbol for sulfur; fourth letter
6. K: normal type = qwerty keyboard, the index points to this letter
7. H: A.T. Liang (2nd 88)
8. V: Vanadium (50.941)
Entering "pxvwdfkhv" as the answer will prompt the response:
"Haven't you encountered this kind of thing before?"
This points to Julius the Third. Decoding the message using a ROT3 caesar cipher, the resulting word is "mustaches" which is the answer to this puzzle.
