Old Kingdom : The Forsaken
The Silencing Stones
A seemingly innocuous round stone of white and gold marble able to absorb all sound in a ten foot radius. Three of these stones were said to have been made roughly 500 years ago by the Necromancer Dulaigne. He would give one to a dead hand to negate the Bells of the Abhorsen and leave them vulnerable. At least one of these stones is in the hands of the Clayr. Another has been seen in recent times by Muriel and Evalyn.
