I'll join.
The flavor is pretty basic. You have an intergalactic human empire, ruled by an emperor and various noble houses beneath him. You have a guild of navigators that creates specially altered humans that can quickly travel through the galaxy by entering "alternate space" and navigating it using a drug called spice that's only produced on the desert planet Arrakis that is the setting for the book Dune. On the technology note, personal shield generators are highly effective, so infantry combat uses melee weapons or dart throwers that can move slowly enough that they can bypass the shield's defensive settings. There's also other specially altered humans called the bene gesserit, which are basically psychic witches, with a very notable ability to control other people by using what's called "the voice". And I'll make a quick reference to assassin drones about the size of a bee being a thing, and possibly cloning technology.
