I have a few:
- Chosen ones, fate, destiny, &c. When you get down to it, a story with these themes is one where a single person or handful of people is ontologically, cosmically better and more important than everyone else. It's eerily similar to that right-wing meme about how "most people are just NPCs" (though I disliked the trope before that meme ever took off).
- Way too much importance being given to bloodlines by the narrative (note, this is different from them being given importance by characters or societies in the story).
- All of the good characters are handsome and beautiful, while all of the evil characters are ugly and disfigured (with the possible exception of a femme fatale or two).
- Races that are inherently, unchangeably evil down to the last individual regardless of upbringing, society, or material circumstances.
At one point they go to planet that recreates a 1800s England and there a scene about how unions ruin everything. Also some weird sexual violence so the politics are rough. I seems to me the book isn't worth going back to but if you feel different I'd hear your assessment.
That sounds like what the "baddies" of this series were doing with their undead soul powers.
