Sergeant Dalen

Sergeant Dalen was one of the defenders of Bastion's Keep. During the siege on the keep by Azmodan, he encountered The Nephalem, who had succeeded in lighting the signal fires. A vision of Azmodan appeared to mock their efforts, but The Nephalem assured Dalen it was just a vision, designed to undermine their morale. With that done, Dalen directed The Nephalem to the Stonefort, where the keep's catapults could be raised.
