Furbaide Ferbend

[2] In the sagas Furbaide's mother is murdered by her sister Medb, Conchobar's former wife and the future queen of Connacht, in the poem by her nephew Lugaid Riab nDerg, and her child is born by posthumous Caesarian section.

[6] At the age of seventeen he fights in Conchobar's army in the Battle of Gáirech and Ilgáirech at the end of the Táin Bó Cúailnge ("cattle raid of Cooley").

[3][7][8] In the saga Mesca Ulad ("the intoxication of the Ulaid"), where he is said to be Cúchulainn's foster-son, he fights against the Erna, but he is so beautiful none of them can bring themselves to wound him.

[9] After Conchobar's death his son Cúscraid Mend Macha succeeds him as king of the Ulaid, and gives his brother Furbaide the regions of northern and southern Tethbae.

The next time he sees Medb bathing, he shoots the nearest missile to hand – a piece of cheese – at her, and kills her.
