The message seems to be directing me TOWARD some of the words in it. That aligns with the instructions: "In this magnificent library, you will find all types of books - books on every subject ever studied by every author who ever set pen to paper! You will use these resources to help you find specific code words that you will use to help break the spell that is keeping everyone captive here."
"You will stumble upon a passage from a book, its words glowing brilliantly at you."
And there will be specific book quotes in it which is currently what I'm searching.
