Nefja Holmunardottir joins the hird in Skjern after Something To Prove is finished. Just like Ketill, she can't be removed from the party when the party management screen is opened when talking to Skallagrim or when you start the second act of the game.
Nefja is honourable and an assertive woman, unlike her twin sister Eyfura Holmunardottir, who plays the classic damsel-in-distress role due to her unidentified illness. This is will probably kill her without the proper medical treatment.
During the second act, she can be romanced. This is randomly started as an event while the party stays at a campsite.
The Frail One and The Helsott Curse
Due to her primary statistics, she can be become a great scout who can fight on the front lines due to her endurance being quite high. With her Sense score being four points, she has also access to many support skills.
