When Ozpin starts talking to Oscar it ' s actually a prerecorded message that Ozpin left for if something happened to him . Now this one is kinda a longshot but I think Oscar is actually Ozpin as a kid and all the scenes involving him are flashbacks . I don ' t expect this to get confirmed or denied but it ' s a head canon of mine Nora has nightmares regularly and will often crawl into Ren ' s bed at night . <| sep |> Freemason here . This is what we call a ' cipher '. Masonic ritual is normally presented from memory we aren ' t supposed to write it down in a way others can read . The ritual is traditionally is learned ' mouth to ear ' from a more experienced member , but in reality , most also use books like this , where the ritual is presented in an obfuscated form . While today most Grand Lodges have official ciphers , back when this was printed they were verboten , and produced independently . Ritual varies from place to place , so these unofficial books are actually of limited value for learning . In general , the cipher can ' t be mechanically expanded to the original there isn ' t enough information . It ' s goal is to provide a jog to the memory of someone trying to memorize a passage they ' ve already heard many times . Between their memory and the text , they can make sure they aren ' t missing any words or phrases . The actual ' secrets ' are a very small part of the ritual , and these books will usually just be blank where those are presented . The first line of the second paragraph on the right page expands to The Corinthian , the richest of the five Orders , is . It is part of what is called the ' Middle Chamber Lecture ' in the second , or Fellow Craft Degree . While these books are an interesting curiosity I have a small collection , they aren ' t particularly rare or secret , and as codes , they ' re very simple .
