Frank Herbert’s Dune (season 1)

In the 11th millennium Shaddam IV., ruler of the Galactic Empire, rids himself of his competitor Duke Leto by giving him control of the desert planet Dune also called Arrakis; fully aware that its present owner, Baron Harkonnen, will not give it up without a fight. The reason is that Arrakis is the source of the valuable spice, a substance produced by enormous and dangerous sand worms, which bestows special mental qualities on anyone who consumes it. A short while later Harkonnen does indeed succeed in ambushing and massacring Leto and his men.
