The Phantom Clan is known as the Underhand of the Emperor. They are known for their courtiers' abilities. Their ghostwalkers are experts in assassination and espionage. Phantom knowledge is not shared with outsiders, but is a true thing of power. Phantom architects have constructed many key structures throughout Honshu, and, as a result, many of those structures have secret passages and rooms unknown to all but the Phantom clan. It is a Phantom tradition to always be masked, or face painted.
