The Wheel of Time - The Call of the Horn
Seekers of Truth
The Seekers for Truth are Seanchan who search for treason and other wrong-doing. Property of the Empress, they act as spies amongst Seanchan and its enemies alike. Seekers wear raven tattoos on their shoulders, though they are less willing to shown them off than the Deathwatch Guards with their own tattoos. Seekers also carry identification plaques for when the need arises.
Anyone must obey the Seekers of Truth, even one of the Blood.
