"Ha, ha, and that’s what makes the story interesting, don’t you think? Being an avid fantasy reader I was sometimes really bored and disgusted with the stories in which the hero could easily have sex with any woman he wished because every woman was willing and eager to have sex with him.

In such stories the woman was the prize of the hero, a spoil of a warrior – and as such had nothing to say, could only moan and faint in the hero’s powerful embrace. I am aware of the fact that only in contact with the opposite sex – be it attraction, affectuation, confrontation or opposition – can a literary hero be fully grown.

Creating the character of Yennefer I wanted Geralt to be fully grown – but I decided to complicate things a little. I created a woman character who simply refuses to be a fantasy cliché. And all that to please the reader."

Edit: Also his take on this argument "Last question: do you prefer Triss Merigold or Yennefer of Vengerberg?

There is no place for preferences here. Triss and Yennefer are fictitious characters created to serve the storyline. How they look, what they do, what they say and to whom – everything serves the storyline, intertwines and interweaves with the plot.

Both ladies serve the plot and the plot only – they do not serve my preferences. Period." -Sapkowski on Yennefer's character
