American fantasy novelist, author of The Last Unicorn, who wrote the teleplay of the third-season Next Generation episode Sarek, his only Star Trek credit.
Peter S. Beagle is an American author best known for the fantasy novel The Last Unicorn, and for screenplays including the animated film of The Lord of the Rings released in 1978.
His one Star Trek credit is the teleplay of Sarek, broadcast in 1990, which was based on an unpublished story by Marc Cushman and Jake Jacobs. Mark Lenard returned as Spock's father, now elderly and suffering from Bendii Syndrome, a condition that erodes his emotional control and spills his feelings on to the crew of the Enterprise.
The episode is remembered for the mind meld through which Picard carries the ambassador's emotions, and it was one of the first to tie The Next Generation firmly to characters from the original series.
