Yes, she is the one inside Khoonda. I believe you have to talk to her and find out about Vrook. That is where you get the quest to look for him, I think. After you find out he is not in the sub-level, you have to go back to the crystal cave. In the one cavern you will see a group of mercenaries and Vrook in a cage. Before you finish the sub-level, no one will be there.
After you talk to Vrook, you can either side with him (lightside) or kill him/imprison him in the cage (darkside). After that, mercenaries will confront you outside the cave. That's where you can either choose to fight against them or side with them. That is where the whole "Battle for Khoonda" starts.
Hope that isn't too confusing. That should help. If it doesn't, keep asking.
