I believe it's Triss. Is it Triss?
Triss is my final answer.
OH yeah, here's my motivation:
Determined to outlive the most powerful
- Other sorceresses, like Sile or Philippa, Dethmold even.
Already one beat her to death's door
- This is about Geralt, because well, he died.
Now only the one who is most despised
- I think this is about Geralt as well because Witchers are despised
And she will be well satisfied
- Well... I guess we could say the relationship between Geralt and Triss was satisfying for her
