Exactly! This is another reason why I thought it may be a subtle reference to the game.

You aren't the first to wonder if this particular "book" is a reference to the game, but I don't think so. It's more likely a reference to The Decline and Fall of the Roman Empire, which happens to be a six-volume work.
Thanks for the link to the previous discussion. It being a reference to The Decline and Fall of the Roman Empire makes more sense considering the references to books from the other quests. Thanks for pointing it out, I wouldn't have thought about the connection with it being a six-volume work!
