Thereafter he arrived over rough places and difficulties, and no ambush befell him, till he came out over Fid Cianach in Mag Muagnige and went northward over the Righe.57 In that place he sat down, and Suide Moling (‘Moling's Seat’) is there. The sons of Aed Sláne and their clerics came to the place in which Moling was biding. ‘'Tis far hither, O cleric,’ they say, ‘thou hast extended (ro righis) our tryst. Righ Mná Nuadat (‘Forearm of Nuada's wife’)58 has been its name till to-day, and Righe Laigen will be its name in future. And it will henceforward be the boundary of the two countries.’
Then he went home, having got the delimitation between Leinster and Húi Néill. Then the Leinstermen brought him a great tribute for the getting of the boundary by them.
