Orcs of Stonefang
Basically, a palantir.
Wondrous item: 9,000 gp
Power (At-Will): Standard Action. Until the end of your next turn, any person speaking into one stone can be heard by those near the other stone as though he or she were standing in the other stone’s place. At the end of your next turn, both stones are exhausted. With a minor action, any character touching a single stone renews the set.
See PHB p. 255
You have been given Hadarra Glintshield’s sending stone. It is attuned to a stone belonging to her cousin Flinka, who vanished during the orc attack.
