HBO's Dune: Prophecyoffers us a look at what the world of Dunewas like 10,000 years before the rise of Paul Atreides. Naturally, that time jump means we get to meet a whole new cast of characters — a process that can be daunting given Dune: Prophecy's intricate sci-fi lore.

But don't worry! We've assembled a handy-dandy character guide to help you navigate the ins and outs of Dune: Prophecy, from the Sisterhood to the Imperial Royal Family. You'll be an expert in no time.
