Birthrights: Kill or Banish Gorm?
At the end of the Birthrights quest, King Harald will ask Eivor what fate Gorm deserves. At this point you’ll have three choices:
King Harald states that he understands your decision, but that it would be too easy. Gorm is renamed to Worm and is banished.
King Harald states that this is a wise choice, as Gorm will now suffer for a longer period of time. He is still renamed to Worm and banished.
This response results in Gorm still being banished and renamed to Worm. The only difference is that King Harald admires Eivor for asking him to decide.
