The Yasuki family were the public face of the Crab Clan. Where the other families all dealt daily with the horrors of the Shadowlands, the Yasuki were the Crab's diplomatic and economic engine. Yasuki courtiers were seen in courts representing the Crab much more than any of their other families, and their merchants were by far the most crafty in all of Rokugan. The Yasuki family was originally a family of the Crane Clan, but broke from the Crane in the 4th century and were quickly incorporated into the Crab Clan.
