I like these and have similar thoughts, with some tweaks.
Maybe they follow the novels mores
Smugglers oh yes I strongly agree
Butlerian Jihad and Forbidden Tech
(focus on …
The history, the myths, the martyrs
the thinking machine
the titans
brains in jars, cogitor and their secondary’s
the cymeks
story options of what could be lying around left from the machine days
deep dive into banned tech, and how they empire compensates now without the tech
the orange catholic bible
Ix & Richese
Great Schools
(could be one big book of smaller supplements)
(Sisterhood, Mentats, Suk Doctor, Navigators*)
The Structure of an Empire
Landsraad & the Great Houses
CHOAM
Padishah Emperor
(House Major & Houses Minor)
(Deep dive into the existing houses with even more options and details on custom house design)
(History and options of Assassins)
(History of the transformation from the league of nobles to the current empire)
Navigators
(This could be a deep dive into space travel throughout the Dune universe
Transition through FTL Travel, FTL Travel, Space Folding as well as
a deep dive into the Navigators, and players options for guild agents)
Empire of a Thousand Worlds
(worlds, worlds, worlds
Also brief comparison of worlds across the ages
Arrakis = Dune = Rakis
Synchronized Worlds vs League of Nobles vs Unaligned
Era’s & Timeline
(this would be both a great collectors item and campaign aid that would touch on but not delve to far in to each, it would also allow a newer gm to taste and choose where he wants to go , and give an easier time of it. Because we know tackling the Dune universe has never been easy).
Agreed on the outsiders
Fringe Elements, Flesh Merchants
