In William Goldman’s fantasy novel The Princess Bride, much of the story takes place in the fictional country of Florin.
Florin is the home of Buttercup, the central princess, and the setting for major events involving Westley, Prince Humperdinck, Inigo Montoya, and Fezzik. Its neighboring country is Guilder, creating the political tension surrounding Buttercup’s arranged marriage.
Goldman’s 1973 novel presents itself as an abridgment of a supposedly older work by S. Morgenstern, but that framing is part of the book’s metafictional joke. Goldman is the actual author, and the invented source text and editorial commentary are storytelling devices.
The famous 1987 film adaptation also uses Florin and Guilder. Westeros belongs to George R.R. Martin’s A Song of Ice and Fire, while Genovia is associated with Meg Cabot’s The Princess Diaries, so neither is the country in Goldman’s novel.
