I have done the first two parts: Met Tealor and did the optional Get keepers garb. Now I am trying to "support the excavation in Old Dothulgrad, but when ever I highlight that in the Journal and choose Show on Map, it leads me back to Tealor in the Emporium, where I last left him, at the end of the long table. The conversations available are the ones I already went through: "About the Cycle...", "You were imprisoned...", etc. etc. I go through them again, and when they are all used up the quest arrow is still over his head.
What did I miss?
