A silver ring of dwarven craftsmanship, runes etched into the polished band. When worn, the ring is cold against the skin, almost unnaturally so.
The ring likely a gift from a Dwarven emissary, it is not truly known how it arrived in Kahazrhet.
The ring warns the wearer of any near them with intent to harm them by growing warm. The silver runes are a magical ward of dangersense.
