Oculus

The Oculus is one of the five hidden artifacts. Also known as the "Infinite Eye," the Oculus is the prototype after which all-seeing stones and scrying tools are pattered. This crystal artifact came from the Rio Branco preserve in Brazil and is reported to be the most dangerous of the artifacts. It allows the user to see anywhere and everywhere all at once, but most people cannot tolerate the vast overwhelming sensory input. Not much is known about the artifact's guardian or traps. The Sphinx had the demon, Nagi Luna, use the Oculus to locate The Eternals. The Sphinx also forced Kendra to use the Oculus, while she was trapped at the home of Torina Barker. It is described as a crystal sphere, small enough to hold in your hand.
