So we just got a LOT of tweets from Quixote; now that they've stopped, an attempt to organize what we now know.
- The two relevant pieces of information from the calendar are the month May
- and the days 20 and 23
- Brad later mentions that 20 and 23 connect to the letters T and W, which he and Deanna used to put on state tests as their place of birth-- standing for "The World"
- It's unclear whether this is the entire significance of 20 and 23.
- Deanna alluded to the Playfair Cypher
- She also suggested using Tara's name as the key
- She also made mention of Digital Roots. It is unclear whether these should be used for 20 and 23, or for
- the last message from Deanna-- a string of numbers: "1021 2204 0407 1004 0907 1402"
- 2204 was originally given as 2304, but then Deanna sent a correction tweet. It's unclear whether this is a GM's typo, or another clue.
Edit: Agora solved this one.
He split Deanna's string of numbers into pairs, converted them into letters, and put them through the Playfair cypher with the keyphrase "TARA".
This gave the message "MONTHFIELDST"
As "month" clearly refers to May, the month the calendar was open to, this gives us Mayfield Street. The only Mayfield Street in the right part of the COUNTRY is North or South Mayfield Street in Kennewick, WA (3 hours drive from Seattle).
Quixote confirmed this as the right street, and asked for the house number.
Since the digital root of 2023 is 7, he gave Quixote the number 7 for the address.
This appeared to be confirmed as the right address, and Quixote said he and Brad will go there tomorrow.
...and then he got
this.
Bloody hell, it never seems to end...
ALSO: I think Agora deserves a special title for his accomplishment (seriously, if you were online when this was happening, the puzzle was IMPOSSIBLE and making us cry). We tossed some ideas around the chatroom, and 'Meta-Cryptist' sounds pretty good. Who else votes he gets the title?!
