Talk to Gwyn about the key and ask about her parents you will need to show the vault key to the castellan and then check with the gnome locksmith in Tirin's Rest about key forgeries.Īt the locksmith in Tirin's Rest, head to the secret lab in the back - if you visited this merchant before, you will notice the door but cannot enter it. Locate her in the Warsworn detention area and move the mission onwards.

Head back to Helmgard Keep once you are ready, and find that the NPC (Gwyn) will be accused of assisting the Fahrlangi cultists. Start your butchery and, if you have Detect Hidden at level 5 or more, you should be able to find the secret room in the vault. Enter the vault and notice the bevy of red dots (with at least one point in Detect Hidden).
