These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Nightmare Fuel: The main character is captured by evil creatures and forced to fight for her life in an arena for their amusement, then once she's rescued is condemned for not having resisted unto death and stripped of her powers and courage. Wandering the world as an ordinary person, she's abused in various ways for a long time. Also, Another character is captured by another villain and castrated. The description is not graphic, but very matter-of-fact.
All of which pales in comparison to the final arc of the third book, in which Paks willingly surrenders herself to the priests of Liart for five days and nights in order to give the Duke and his men time to reach Lyonya. She spends five days being shorn, flogged, whipped, burnt, bled, crippled and raped, and only the intervention of her gods restores her body to health.
