Shouting Stone

Though few in the north know of such an object, those of the Empire use a Shouting Stone regularly.  A Shouting Stone is usually a small, round stone with a hole in the middle to have a rope or necklace run through.  Magical runes run all over the stone (or other small object the maker of a Shouting Stone wants to make it) and it glows faintly.  The stone is used to allow a person be heard a longer distance away then shouting would allow.  Most generals use these stones in battle and the general assembly uses it to be heard during debates.  As long as a person is holding the stone in their hand they project their voice up to five hundred yards away.
