Dave Strider's rap by Octopimp by Dancing Monkey.
Getting through the Dead Trenches leads to Anvil of the Void.She is located in the small room just before the final large open area.This area is only accessible once you have found Branka's journal in Ortan Thaig.They are fighting on the bridge when the Warden approaches, after the first battle the Warden can speak with Kardol about his mission there and the Blight.Halfway through the second bridge, the Warden will be ambushed by a large number of Shrieks.
