Prophecies of Uikku

The Propehcies of Uikku are the collected writings of one of the Phoenix Clan's foremost prophets. They foretell, among other things, the doom of each of the clans and of Rokugan.

Excerpts
"When the Phoenix burns brightly in the sky, it must leave half its soul in ashes upon the earth. In this way will the flames of the Five cover the Empire in brotherhood."
 * The Isawa family believe that this foreshadows the magical knowledge of their family spreading throughout Rokugan, especially in the formation of the Asahina family and the Yogo family. (Phoenix p. 22)
