I just cracked open my POD copy of DaTR. It has been years since I read it. First chapter in and I didn't realize how heavily Keith was leaning on Dune. I know Frank Herbert's work influenced everyone, but wow.
Offworlders don't just the Trell... just like they don't trust the Fremen.
Grayson is heir to a military legacy... just like Paul was to Leto.
Grayson is in a romantic relationship with with a local girl... just like Paul was with Chani.
Trellwan is a desert planet... just like Arrakis.
Grayson is taught martial skills by a grizzled master at arms not known for his good looks, but who also has a scar along his jaw... just like Gurney Halleck.
I mean... wow.
