Nessus, the notorious centaur from Greek mythology. Murdered by Hercules for abducting his second wife Deianira. He told Deianira with his dying breath that if she were to give Hercules a tunic soaked in his blood it would become a love charm so that if Hercules ever stopped loving her putting the tunic on him would restore his love. But this was Nessus revenge and when Deianira used Nessus poisoned blood on Hercules it caused his death.
