Near the beginning of the Wrath of the Druids DLC you will choose Thorstein’s fate. This AC Valhalla Wrath of the Druids Execute, Brutal Death, Or Cruelty Choice guide details each of the three choices you can make, outlining the outcomes so you can choose what path you wish to follow.
After you capture Thorstein from his encampment, you’re tasked with taking him back to Barid. When you return to the center of Dublin, Barid asks for your advice on how to deal with the situation. You can choose a dignified execution, a brutal death, or a display of cruelty.
AC Valhalla Wrath of the Druids Execute, Brutal Death, Or Cruelty Choice
If you choose A Dignified Execution
Sichfrith agrees with this but Barid says it’s not worth the bother. He decides to confiscate Thorstein’s land and silver, and banishes him from Dublin. Afterwards his son and Eivor question his choice and Barid explains it was to win favor with the king.
If you choose A Brutal Death
Eivor suggests a brutal death is the best solution to dealing with Thorstein. Barid’s son is all for this idea, but Barid is not. Barid disagrees and decides to exile Thorstein, banishing him from Dublin and confiscating all his wealth.
If you choose A Display of Cruelty
Barid agrees and decides the fitting punishment is exile, sending Thorstein away and confiscating his goods.
Ultimately, the decision doesn’t seem to have much impact on the story.
