First, I've created the alphabet key/table, cipher text in numerical form, and plaintext after substitution Alphabet: Numerical Cipher Text: Submitted Plaintext: Second, and more importantly, I don't think we're done with this cipher yet. There are too many oddities for me to be convinced there isn't more information hidden on this page. Here's my list of...oddities: We don't use the circles or lines in this decryption process Every number in the key is used TWICE in the document but only once in the cipher text This is determined by searching the document created by Draz. I've also cross referenced it in a version created by Waterkh, so it isn't a copy error. This includes all number in the key, both primes and non-primes. There are only two exceptions: (547, 937, 257, 499)- all of these numbers only appear once in the entire cipher text (107*, 608, 20, 174*)- 107 appears twice and (608, 20, 174) appear twice but they only appear together once. Why are there numbers in the cipher text and alphabet that are not used in the plaintext? Perfect example is the letter Z. There are 7 numbers associated with it but they are not part of the plaintext. They do not offer any additional functions such as spaces or punctuation. I don't believe it complicates the cipher in any way and could easily have been left out, such as with G, J, or Q. Personally, I think this requires more looking into, but if people have other theories/explanations I would love to hear them!

My request for the scraps was filled by GQ:

@InfestLithium Blundell did confirm that there was a cipher in BO3 that is double-enciphered. Specifically it was during Milo's interview, and it was for "all of BO3", not just before ZNS. My point being that you're basically describing a process of double-encipherment, which has been confirmed. And yes, only the scrap papers remain on ZNS. Its unclear at this point if they are 2 separate ciphers or are linked into 1 cipher with key and plaintext.

@Kalinine I just posted a request for your technical drawings and for the scrap papers. We'll see if anyone can help. https://redd.it/4k9azs

While we're on the topic, could a PC wizard also get a picture of the scrap of paper that's in the dragon room? I'm trying to rule out a turning grille cipher and I need a complete image that's proportionally correct. Specifically I need a vertical shot of it, as if you were standing on top of it and you look down. Thanks!

@DragonGJY A cryptogram cipher is a mono-alphabetic substitution, AKA simple substitution. You substitute one letter of the plaintext with one letter of the cipher text and one letter only. In our case, the key was: "15, AUROBELISCDFGHJKLMNPQSTUVWXYZ". The 15 denoted the offset of the alphabet. Below is the alphabet with the start highlighted. The "AUROBELISCDFGHJKLMNPQSTUVWXYZ" is fairly quick to spot. The "15" in the key apparently means that the 15 of the plaintext is the same as 15 in cipher text. Certainly would not have been my first guess as how to use the 15, but there you go.

New Cipher found on ZNS. It's over by the Green Water. I'm having trouble attaching the picture, but there is the link to the imgur album and here is the original post on reddit. Here is the cipher text as best I can read it: Kvxga pzd lwtv sb pzd Rvtxhc Xoo Fsoxgypw var zzczlqnnsjm, pxb Cupngyl qny zo vsflaxydd kwky zip eixhe laxoktr jwnl yc sar hfjksrdd gvm mzhyrryokzzh he ttu zbq Astirwyh 9 bnahlvjr ss pzd irdihm rc zecunpaa.

I would put money on this being the Shino Numa cipher that's found on The List.

@DragonGJY Here is the long-form of the cipher in excel. The 15 rows is easy enough to understand, but by "offset" it means that you start the zig-zag after traveling 5 lines (starting in the 6th row). It was actually important to do by hand to solve bc I helped me see that there was a secret "space" hidden as the first character of the cipher. If you want a computer to do more of the heavy lifting, check out the Geocaching Railfence Solver.

@Kalinine I think it's a good possibility that the underwater cipher by power (see below for reference) is actually the 5, 25 cipher. After doing more work on it to figure out exactly what type of cipher it is, my new guess is that it's a Nicodemus Cipher. This is due to transposition of both its columns and rows (see below). I'm not 100% sure of this, but what I can say is that assuming this method, you find that that the column length is 25 and that the proper start of the plaintext message is 5 rows down in the cipher text. The other piece of evidence is that I feel both of the transposition ciphers "go together," and that their keys would as well. Since I'm very confident the newest cipher solved is the 15, 5 cipher, I think it makes it more likely that this is the 5, 25 cipher. Of course, we don't really know until we solve the other ciphers on the map, namely the scrap paper ciphers. And there might even be a new one waiting to be discovered still.

@Nieno69 My thoughts exactly!

@whats his face I think the next step is to figure out how many total unique numbers there are and to get the frequency of each. If there happens to only be 26 of them, the cipher becomes easier as we just start substituting based on frequency.

For the newest cipher (Zipline Cipher), I went back through and attempted to confirm the number of spaces included by creating bars that measured the space between the words: There appears to be spaces of 3 different lengths, so my conclusion is that the different sizes correspond to 1space, 2spaces, and 3spaces. This would bring the number of spaces in the cipher to 87, and the total length to 505. One limitation to note is that I cannot definitively say how many spaces appear at the end of each line. I assumed there was only 1, but it could be more, thus increasing the total character count. Ways to attack this cipher: This is most likely a transposition type of cipher, which reminds me of the other transposition cipher on the map. On ZNS there have been multiple uses of Vigenere ciphers being used, so it is possible that the transposition cipher has repeated. The one I solved was a strange variant of a columnar transposition cipher. I solved it using techniques for a columnar transposition, but the final composition was very different from any that I had heard of. This makes me wonder if I did not solve the cipher the "correct" way. If that's the case, then spending time figuring out the "correct" way to solve the transposition would help us understand how this cipher could be solved, especially if the two transposition ciphers are 1 and 2 on The List. However, if we apply the same techniques I used before, then we run into difficulties. I found the column length by noticing the 115 in the cipher text and knew they had to be associated. The only nice landmark found in this cipher, like @Nieno69 pointed out, is the letter "Q". In English, Q is always followed by the letter "U", so we can use that to our advantage to connect 2 columns together and use that to branch outwards. FYI, this is the current route that I'm taking at the moment.

@Nieno69 I also noticed that there might be a connection between the one I solved and the new cipher. I was thinking about how the cipher I solved had columns that were 25 characters in length, so my thought was to apply it in some way. I do like your observation that the 5 may indicate the starting point for the cipher text. Have you tried your theory yet? @Tac The Shinonuma cipher hasn't been identified yet, but the Aurora Borealis key is the Cryptogram cipher that Liz solved. If you map her alphabet, it was offset by 15 letters as the attached image of the excel page shows.

@Kalinine 5th piece is on a shelf near the purple 115 water in the bunker. And unfortunately it seems like the only way to use the free-cam mode in the dragon room is to be a wizard.
