Denis Villeneuve’s Dune movies brought Paul Atreides’ story to the screen, but the story of the Kwisatz Haderach actually started millennia before he was even born. The Bene Gesserit worked for ten thousand years to bring about a super being who could guide humanity towards a better path. Now HBO’s Dune: Prophecy will show us those early days when the Sisterhood first put their long term plans in motion.

And yet, not even going back that far tells the whole tale. Dune‘s history is much longer than our own. How far back does it go and what is the state of the universe at the start of the show? To help you understand what’s going on, why, and when, here’s a simplified timeline to help you understand Dune: Prophecy.
