Leonan inspects the books as he puts them into his pack. From what he can work out they are manuals for things Leonan doesn't entirely understand they appear to be for some form of vessel but it has no sails or rudder and the diagrams given only add to the confusion they are incredibly complex and intricate, some sections Leonan recognises as magical scrawl like a poor novice wizard would scrawl in his first spell book.
Another set of books makes more sense they it appears to be a diagram of the bodies of several creatures ranging from humanoids to purple worms complete diagrams of muscle, nerve, vascular systems this could greatly improve existing knowledge of the way bodies work.
The final book after some inspection appears to be a journal or a log the language is completely indecipherable.
