Kaimetsu-Uo

Kaimetsu-Uo was the eldest son of Hida Osano-Wo and half-brother of Hida Kenzan. Kaimetsu-Uo left his origins in the Crab Clan when his father told him that his bastard half-brother would inherit the position of Clan Champion. Kaimetsu-Uo went east with those loyal to him and his mother, originally of the Matsu family. They found their way to islands to the east of Rokugan where he founded the Mantis Clan and named them the Islands of Spice and Silk.

Death of his Father
In 97 Osano-Wo was murdered and since Hida had become a recluse and Hida Kenzan had to run the Crab Clan his son Kaimetsu-Uo was given the opportuinity to track the traitor responsible. Kaimetsu-Uo leaped at the chance and quickly tracked the person to Shiro Shiba in Phoenix lands. The Phoenix first refused to open their gates, but when Kaimetsu-Uo cried out to his father for vengeance, lightning struck the gates of the castle, opening them. The Phoenix saw this as a sign to release the traitor to Kaimetsu-Uo and their scholars requested Osano-Wo be granted the status as Fortune of Fire and Thunder from then on. Because of Kaimetsu-uo's loyalty to his father Osano-wo declared the Mantis to be his favored children.
