The stories of Cú Chulainn's childhood are told in a flashback sequence in "Táin Bó Cúailnge". As a small child, living in his parents' house on Muirthemne Plain, he begs to be allowed to join the boy-troop at Emain Macha. However, he sets off on his own, and when he arrives at Emain he runs onto the playing field without first asking for the boys' protection, being unaware of the custom. The boys take this as a challenge and attack him, but he has a "ríastrad" and beats them single-handed. Conchobar puts a stop to the fight and clears up the misunderstanding, but no sooner has Sétanta put himself under the boys' protection than he chases after them, demanding they put themselves under his protection.
