The Lord of the Rings is a classic book from ancient Stark. By some strange way, it became known in Arcadia. In The Longest Journey, when April visits Abnaxus, to her surprise she finds it among other books and comments on how the classic fiction literally crosses all borders.
The Lord of the Rings is referenced a few times in both games. In The Longest Journey Crow claims he'll be called "The Lord of the Winds" soon. In Dreamfall, after telling Zoe about winning the title of the best sidekick of the month, he complains because an "annoying man-child with the hairy feet and the chubby face", who did nothing but carrying someon up a hill without cracking a single joke, won that title the very next month.
