The world of Dune, initially conceived by Frank Herbert and expanded over the years through books, film, TV, and video games, is a vast one. The Imperium is ruled by House Corrino, but the scheming of other Houses like Richese and Harkonnen keep the rulers on their toes. Meanwhile, the desolate desert planet Arrakis remains a key figure due to the production of valuable spice. Dune: Prophecy, a new series from HBO, gives viewers a look into that universe 10,000 years prior to the events of the original Dune.
