"You must be mistaking the Clan of the Pointed Stick for one of the rational societies of paranoid, celibate martial artists!"
The Clan of the Pointed Stick is a secret society of paranoid, celibate martial artists. The most well-known member of the Clan (and indeed the only known member) is Sensei Ping, the only man alive who knows the Wu-Han Thumb of Death. If the Clan sends out any of its members, and they do not report their safe arrival at their destination, the Clan will send out a group of assassins known as Shi-Yu Fighters to kill anyone responsible, even the party to whom the clansman was going to visit.
