Ryuki was a chui of the Imperial Guard. In 1127 during the Clan War he rode to Crane lands and passed an Imperial message to the Captain of the Imperial Guard Seppun Ishikawa. Ryuki followed Ishikawa after he left the guard and joined the Crane Clan. They moved to the Lion-Scorpion border, in the Spine of the World Mountains, looking to unveil the Scorpion conspiracy to poison the Emperor and secure control of Rokugan.
