Fictional story elements introduced in 1955

Multivac is a fictional powerful computer appearing in over a dozen science fiction stories by American writer Isaac Asimov. Asimov's depiction of Multivac, a mainframe computer accessible by terminal, originally by specialists using machine code and later by any user, and used for directing the global economy and humanity's development, has been seen as the defining conceptualization of the genre of computers for the period (1950s–1960s). Multivac has been described as the direct ancestor of HAL 9000.

Charn is a fictional city appearing in the 1955 book ''The Magician's Nephew'', the sixth book published in C. S. Lewis's Chronicles of Narnia, written as a prequel to The Lion, the Witch, and the Wardrobe. Charn, and the world of which it is the capital city, are the birthplace of Jadis, also known as the White Witch, who later seizes control of Narnia.
