After the Cataclysm
Dunne was one of the original four party members, along with Mjoll, Miressë, and Erevan. After defeating The Shroud in Zakhar, Dunne promised that he would join their organization as an assassin in order to protect his father. He was able to first help Mjoll and Miressë defeat the lich Ilion Lystari at the golden tower in Martyr’s Feywild and celebrate victory in New Ilion.
Once the heroes were feted, however, he joined up with The Shroud and accepted almost everything they gave to him. When Mjoll and Miressë met him next, in the City of Brass on their way to recapture Orret, he called himself Gone and literally stabbed Miressë in the back. With the help of Pietra, they defeated him and mourned the loss of their old friend.
