WARNING: SPOILERS ahead for Dune: Prophecy.Max’s seriesDune: Prophecydropped a huge bombshell when one of its main characters made a small reference to humanity’s original home planet,“Old Earth”, in theDuneprequel’s episode 5. Set millennia in the future, the story ofDunetakes place on a variety of planetsthroughout the Known Universe, including Caladan, Giedi Prime, Kaitain, and, most notably, Arrakis. However, Old Earth is all but absent from the story, with hardly any ofthe characters in theDunefranchiseeven mentioning it or humanity’s time on the planet throughout the saga’s many stories.

While the narrative ofDunehas mainly been focused on humanity’s future outside of Earth,the books' multiple writers have built up a considerable history surrounding Earthand what’s become of the Big Blue Marble. So far, theDune: Prophecyseries and director Denis Villeneuve’s twoDunemovies have taken this source material and made a vague but overall faithful adaptation of its canon, including the world that humanity left behind.

Dune’s Authors Changed Over The Years, Leading To Complex Lore

TheDunefranchise is the brainchild of author Frank Herbert,who had completed six novels for the series in his lifetime centered around Paul,which focus on the stories of Paul, his children, and the Bene Gesserit. It was during the franchise’s second novel,Dune Messiah, that Emperor Paul began exploring the history of Old Earth, comparing himself to leaders like Adolf Hitler and Genghis Khan as he tried to pave the way toward a better future following the holy war he unleashed on the Known Universe.

Though Brian Herbert carried on his father’s legacy for almost 40 years, theDunefranchise’s change in writers have led to differing accounts of the events in its timeline, including the fate of Old Earth and its history with the dreaded AI, the “thinking machines.”

However, Herbert’s son Brian took over writingtheDunebooksfollowing the former’s death in 1986, expanding the lore of the franchise with several prequels and sequels with co-author Kevin J. Anderson. Their combined effortsbrought the total number ofDunebooks to 23. One of their works, 2012’sSisterhood of Dune, actually became the main inspiration for Max’sDune: Prophecy.
