Received from: automatically after finding the golem registry [Anvil of the void]
Description: You'll be allowed to start this quest soon after you've defeated Caridin or Branda and after receiving a crown. Look around the area to find a large panel made out of stone (M59, 10). Clicking on the registry will initiate this quest and you can also ask Oghren what he knows about the thing you've just discovered. Leave this area and travel to [Orzammar - Diamond quarter - Shaperate]. All you have to do right here is to talk to Shaper (M53, 3). He will reward you for your efforts with a master rune.
