Examining the market stalls in more detail, she saw that each one included 
a man who did nothing but sit at a table and decipher books, writing them out 
on long sheets of foolscap and handing them over to other people, who would 
read through the contents, consult rule-books, and dictate responses to the man 
with the quill pen, who enciphered them and wrote them out in books that were 
then tossed out into the marketplace for delivery. The men with the quill pens, 
she noticed, always wore jeweled keys on chains around their necks; the key was 
apparently the badge of the cipherers' guild.
