Status Updates From Warlock of the Witch World ...

Lots of themes and exact plot points here are similar to ones in "Dune", like the genetically distinct witch-subraces where the psychic powers only belong to women with the book's protagonist being the first male individual to possess them. I wonder if Frank Herbert and André Norton were aware of each other or arrived independently at the same ideas at the same time?

got a couple of the Witch World books at a science-fiction convention earlier this year and I found out that the public libraries where I live have another volume so I decided to read them, looks like a "science-fiction story where the main characters only have a fantasy genre vocabulary for understanding things because their spacefaring civilisation collapsed and regressed to a mediaeval level of technology" thing
