Kalendale bemusedly opens an aged-looking tome written in Gnoll. "How rare to see a book printed in such a wild language. Rarer still for it to actually be written on such subjects! Let's see what sort of information this book contains... Oh, and this one as well," he adds, pulling down another in Orcish. "I haven't had to speak these languages in a while, thankfully, but I don't think a translation should be a problem."

Not entirely sure what I'm going for here, possibly information regarding magical history and/or deities, the status of the gnoll or orc races or whatever else GM deems of note to be found in such books.
