In the aftermath of the battle, Urgala related to Levina that one of her former adventuring companions, a wealthy knight named Harthos Zymorven, had a Giantslayer. The last time Urgala spoke with him, Harthos was living in Zymorven Hall, his ancestral keep on the Rauvin Road northwest of Silverymoon. Urgala says she believed Harthos might be willing to part with the weapon if Levina mentions her name to him and explains her reason for needing it.
Quest Update. Levina found Lord Harthos Zymorven and requested the weapon, but the lord reported his son Harthal Zymorven had stolen it, after the lord disowned him from marrying a common thief from Yartar.
