I was at one time, immersed in the Darkover series by Marion Zimmer Bradley. I have read 'almost' all of them.
There's almost no 'science' in them, even though the basis is 'ship from Earth rediscovers lost colony where a few humans interbred with vaguely humanoid aliens, acquiring various degrees of psychic powers.
   So, the meat of the series explores the conflicts and personalities and resultant society as it developed BEFORE rediscovery and after.
Later books, sometimes shared by the author with other female writers focuses on an Amazon-like group of women.
   In such a long, complex series there are inevitable contradictions about relationships and timeline.... but one can pick & choose which aspects of the culture to explore.
