The books cover a variety of topics, and languages; the vast majority are not written in English, and many are in scripts you don't even recognise. There is no obvious pattern or system as to how the books are organised. Of the books you are able to identify through illustrations, several are on anatomy, with a few books on organic chemistry and atlases of obscure corners of the globe. Those in English are fairly mundane; scientific journals and encyclopaedias, for the most part.

You find one book on the occult, written in what you suspect to be Greek. It is bookmarked at a page showing how to set up a magic circle using salt and candles. Skimming through the rest of the book, the other illustrations are mostly other magic circles or sigils; there is nothing about the tentacled thing.
