Titan is the fantasy world where Steve Jackson and Ian Livingstone's Fighting Fantasy and Sorcery! gamebooks and novels are set.
In most of the books, the Titan world is in the typical fantasy medieval setting. It contains typical beings of the genre(such as goblins and elves), but also original creatures (such as the loud-voiced Jib-Jib) and recurrent original deities (See List of Titan deities).
In a few books, the Titan world is brought to a contemporary setting. One notable example is in Appointment with F.E.A.R., a comic-book-based adventure in which Titan is a urbanized town in the USA where superhero and supervillains collide.
