However, the chest will be closed on visiting with the Duke, and can be opened without the ring.
The chest can be burgled before or after Reward and Responsibility, and the mantle taken - if the mantle was stolen before the quest, Duke Edmun will not attempt to open it. The chest contains a single Paladin's Mantle - if the genuine ring was returned to Aldous during the quest The Wyrmking's Ring, the Duke may open the chest during Reward and Responsibility - a forged ring will fail to work. The Treasury contains a magick chest which can only be unlocked with the use of the authentic Wyrmking's Ring. However, the event is interrupted by Ser Ivo, starting the quest Deny Salvation. Reward and Responsibility - the Duke invites the Arisen into the Treasury in preparation of a special task.
