The broken geas that led Conaire to his doom was the warning not to go to Da Derga's Hostel; having also been warned about the way to the hostel, he met there three men dressed in red and riding red horses, that were indeed messengers announcing his death, but he ignored them. Once he arrived at the hostel, where his enemies were, they attacked him and his men and Conaire and many of his warriors were slain.
