IX (Dune)

Ix (Dune)

Ix /ˈɪks/ is a fictional planet featured in the Dune series of science fiction novels written by Frank Herbert, and derivative works. In Dune (1965) it is noted that Ix is classed with the planet Richese as "supreme in machine culture," and that Ixian solido projectors "are commonly considered the best." In Dune Messiah (1969) Herbert explains that the planet's name (a spelling pronunciation of the Roman numeral IX) is derived from the fact that it is the ninth planet of its sun. Ixian devices are commonplace and considered essential throughout the rest of the series, though they sometimes test the limits of the anti-technology proscriptions of the Butlerian Jihad, mankind's crusade against computers, thinking machines, and conscious robots.

In Brian Herbert and Kevin J. Anderson's Legends of Dune prequel trilogy (2002–2004), the name of the planet is originally Rodale IX at the time of the Butlerian Jihad.
