Arrakis —informally known as Dune and later called Rakis—is a fictional desert planet featured in the Dune series of novels by Frank Herbert. Herbert's first novel in the series, 1965's Dune, is considered one of the greatest science fiction novels of all time, and it is sometimes cited as the best-selling science fiction novel in history.

Paul Atreides is a fictional character in the Dune universe created by Frank Herbert. He is a main character in the first two novels in the series, Dune (1965) and Dune Messiah (1969), and returns in Children of Dune (1976). The character is brought back as two different gholas in the Brian Herbert/Kevin J. Anderson novels which conclude the original series, Hunters of Dune (2006) and Sandworms of Dune (2007), and appears in the prequels Paul of Dune (2008) and The Winds of Dune (2009). According to Brian Herbert, Frank Herbert's son and biographer, House Atreides was based on the heroic but ill-fated Greek mythological house of Atreus.
