Ok when you are in the Imperial City at any point in the game, go to the Talos District and find Dorians house. He is a Redguard. Sorry guys i dont know his last name. Anyway once there, perform a sneak attack on him and kill him. MAKE SURE HE DOES NOT LEAVE THE HOUSE or youll have to load. When he is dead take his key and start tapping "A" when the gold is highlighted in his inventory. Keep Hitting "A" until your greedy heart is content. Be warned DO NOT HIT TAKE ALL OR THE GAME WILL GLITCH!!
