First of all sorry if someone has already noticed this and posted about it. I also hope that this is allowed.

I have noticed for a bit now that at the end of each of the recent episodes of The Antiquarium there have been a series of spoken letters one after another. I was bored tonight so I took a look into them to see what I could figure out. Well I did figure it out so I'll put a spoiler over everything from here to the end of the post.

​

The letters form a simple Caesar cypher where the normal english alphabet is offset by a certain number of characters from its self. The trick is that every episode the offset of the cypher changes. LOT 53 which just came out was an offset of 7. The encoded text is 'PAXGVATHTGGWVHGYNLBHGKXBZGXQMBGZNLAXWTKXMAXLMTKLTGWLNG' but the decoded text (with spaces added) is 'WHEN CHAOS AND CONFUSION REIGN EXTINGUISHED ARE THE STARS AND SUN'

I've gone through and decoded a bunch of the other ones and like I said the messages and offset values are different for each episode.

​

Has anyone else gone this far with it?
