The Tharn Speaks Guide:
Once you reach level 25, a banekin will approach you the next time you enter a city. It will tell you that Tharn wishes to speak with you. You have to go to the Mages Guild in your faction.
Speak with him to hear his doubts about the situation, and he will tell you to go on a search for information. Head to the marked area, and enter with Tharn at your side. Explore the area and look for clues about Sai Sahan and where he is being held. Once you have them, Tharn will instruct you to visit Varen in The Harborage. Do so to complete the quest.
