Whisperglass

Small magical devices created by the order of The Silent in the province of Silent. These small object appear like small handheld mirrors at first glance, but a subtle touch with a strong thought can cause the mirror to link with another Whipserglass that the user is familiar with. These mirrors then reflect what the others see but not what they hear. This makes them excellent for communication via sign languages and hidden spys. Occasionally these are hidden in a place of interest but this rare due to the Whisperglass' exorbitant price
