The guy who made us... He kept a few keys to our genetic codes locked on some floppies. Basically so they couldn't make more of us or unlocking certain features, as you will. (Because the military got a hold of us.)
So he had everything on floppy drives, but he used a non-repeating substitution cipher on everything on it. He wrote that cipher down in the margins and everywhere in this book. And I just got both.
