Received from: Nortar [Alsorna - basement - Inside Alsorna] (M2:8)
Nortar will ask you to recover his bow, which he has once lost at Oswaroth. It probably is in the hands of a local drunkard. Begin your search at the "Lion" inn [New Ashos] (M23:2). You will learn that he man's wife is at the house, so head to her (M23:3). Picklock the door and talk about the bow. Offer 100 auras for it and return it to Nortar [Alsorna - basement - Inside Alsorna] (M2:8).

You will get this mission after finishing Chapter I, once you get Gandohar's journal after meeting Cassara again at her room. You have to search New Ashos for people who can give you information on Gandohar's failed experiment. This task begins Chapter II.
