COUSLAND TREASURY

In order to activate this quest you must choose the correct answers while talking to Eleanor. This conversation will take place soon after you've started the second main quest - Howe's betrayal. Eleanor will share the knowledge with you about the family vault and she'll give you a key needed to open it.

In order to get to the vault you must first make your way to Guard post (Human Noble Origin M1, 11). Enter the guard post and click on the door leading to Treasury. You can spend some time examining nearby poles or you can click on the main chest. Collect two unique items - a family sword and a shield of Highever (Human Noble Origin M1, 12). After this you can return to the main quest Howe's Betrayal.
