The Scorpion Clan was known in Rokugan to be the Emperor's Underhand. The Bayushi family was the most respectable family of their clan. Most believed that the Scorpion Clan was involved in nearly every illicit transaction in Rokugan, but the Bayushi maintained a veneer of respectability. For being able to be involved in such actions without taking part on it (at least directly) they had their underhand: the Rokugo family.
