I cant figure out how to complete this quest. I had the 4 part password, I killed the giants in the final room and found no escape route to the surface. But upon returning to the quest giver with the Scimitar in Bargha there is no new dialogue options. Same with Erika and Sulfras. I tried killing Sulfras but still nothing new. What am I missing? I finished the other 2 endgame quests, if that matters. Thanks Wow. Nevermind. just found the switch near the bars.
