From the Ward Grimoire
When worn around the eyes and charged, these Wards can allow surface creatures to see in the magical spectrum. As a result, the creatures can see in complete darkness as easily as clear day, watch the flow of ambient magic, judge the relative power of wardings, and see the auras given off by all living things. A skilled practitioner can “Read” these auras to tell what others are feeling or thinking, and sometimes to gain a sense of their past or even their future.
