Sagacious Zu was once a member of the Lotus Assassins. He joined the Order of the Lotus prior to its reorganization under Death's Hand. Zu was, unlike most of his Order at that time, not at the siege of Dirge, but instead given the order to execute Sun Li's family after learning of his treachery. Zu hesitated, however and the rest of his team killed Li's wife, but he would not let them kill Li's newborn daughter. Instead, Zu murdered his team and escaped to the Imperial City with the girl. He took care of her for three years, before handing her over the Hui the Brave, who ultimately sought out Master Li, whose true identity remained unknown to Zu (just as Hui was unaware of the child's true parentage).
