GERALT, TRUE TEMERIAN: This Geralt is the savior of Vizima and friend to Foltest. He is honorable and interest in the survival of the Temerian state above all.
SPARE ARYAN: Temeria must stay strong and united.
HELP ROCHE: Iorveth is a danger to the state.
CHOOSE ROCHE: Roche is Temeria's last hope.
SPARE HENSELT: Roche must not dishonor Temeria with more kingsblood.
SAVE ANAIS: Last hope for Temeria's bloodline.
GIVE ANAIS TO NATALIS: Temeria must not splinter.
SAVE SILE: Dethmold was your enemy, not Sile.
SPARE DRAGON (Roche-All): The Dragon helped Aryan once, it might help him again. Aryan is wild but still a Temerian.
SPARE LETHO: Killing him will not bring Foltest back. And if Anais wishes to avenge her father one day, Letho will still be out there.
Disagree with some of this.
Letho: If Geralt truly cares for Temeria then he would kill the man who murdered his king. There's no two ways about it.
Sile: Sile admitted that the lodge and her had the dragon under their control. The dragon attacked Temerian troops. Therefore without going through Iorveth's path, Geralt could be led to believe that Sile attacked Temeria. She should die.
Dragon: Dragon attacked Temerian soldiers, Aryan never said he had control of it and Sile did. If Geralt spares the dragon, even if Sile is gone, the lodge could still have control of it. There would be no reason for Geralt to spare something that can attack the kingdom again.
Aryan: This one I'm on the fence. Aryan was a traitor, however, with his half-sister in line to be queen he would stay loyal. So here I can agree with sparing him.
