The Kaiu family are the undisputed masters of engineering in Rokugan.


The Kaiu family are an integral part of the Crab Clan, responsible for constructing its various fortifications and siege weaponry. It was they who built the Kaiu Wall, and their continued efforts have turned it into the most impressive defensive work in the history of Rokugan. When other clans need assistance with fortifications or civil engineering projects, they turn to the Kaiu for help. They are also skilled smiths and craftsmen who create the weapons and armor used by the Crab in their war against the Shadowlands.
