Asahina Kamatari

Kamatari was a family daimyo from the fifth century. He was adept at reading omens, and prophecised events like the Scorpion Clan Coup, the Clan War, the Second Day of Thunder and the ascension of Toturi I. His work was dismissed for centuries but, as his prophecies started recently to being fulfilled, it has become object of intent study. (Secrets of the Crane, p. 20)
