“The World of the Dark Crystal” was a companion book to “The Dark Crystal” (1982); it was published the same year. J. J. Llewellyn penned it as a first-person narrative by the character of Aughra, and it was a terrific, detailed world-building exercise that expanded on the universe of the movie. But Brian Froud’s full page artwork stole the show. (This was an oversized book, too.)
It was a welcome surprise under the Christmas tree when I was in early grade school — proving yet again that my parents had a knack for buying me presents that I never asked for but nevertheless loved.
