Goldbrand is a scripted reward for completing the Quest of Boethiah. To begin your quest, swim to the Sunken Shrine of Boethiah and speak with Boethiah's head. The shrine is marked on your paper map as an "X" north west of Hla Oad. Even so, it is sometimes difficult to find, so I've made a map showing its relation to the nearby Daedric ruins of Ashurnibibi.. Boethiah will tell you to seek out a Sculptor. The Sculptor is an orc by the name of Duma gro-Lag and he lives on the third floor of Ghorak Manor, Caldera. Duma will require 2000gp as well as a "statue book." This book is called "Boethiah's Glory" and can be purchased from Jobasha's Rare Books in the Lower Waistworks of the Vivec Foreign Quarter. Once you have given Duma these things, he will begin building the new shrine at Khartag Point. I do not know exactly how long you must wait, but he was definately done in 1 month of game time. Journey to Khartag Point (northwest of Gnaar Mok) and speak with the restored statue of Boethiah to receive Goldbrand
