Yatagarasu's Feather

Origins
The Yatagarasu is the Japan's name for the three-legged crow of legend. It is also the name of the Crow God himself and is symbolic specifically of guidance. The Japanese Emperor Jimmu is said to have received guidance from Yatagarasu, whose traditional form is that of the three-legged crow. It is most often found in East Asian legends and is most associated with the sun, where the legends say the crow inhabits. The legends are focused in China, Japan and Korea.

Emperor Jimmu was the first emperor of Japan, according to legend. His accession is traditionally dated as 660 BC. He is said to be a descendant of the sun goddess Amaterasu through her grandson Ninigi, as well as a descendant of the storm god Susanoo. According to legend, he was born in 711 BC, ascended to the throne in 660 BC and reigned until his death in 585 BC. He used the guidance of a three-legged crow called "Yatagarasu" to win the final victory which allowed his ascension to the throne of Japan.

Effects
The Feather radiates a golden glow which causes permanent insanity when gazed upon. The podium on which the artifact is placed is kept in an area of the Dark Vault away from the eyes of agents who are passing through, though they can see its golden glow in certain areas. They also report the sound of crows cawing from the artifact when a certain proximity is reached.

NEUTRALIZER GOGGLES AND GLOVES ARE MANDATORY.

Trivia

 * While the effects may not make sense from the point of view of the Japanese legend of the three-legged crow, the main Chinese legend appears to reveal the origin of this feather. See "Sun Crow in Chinese Mythology
