Ere long he met a chariot and fifty women accompanying it.

In it was Buan the Queen, wife of Mesgedra, returning from a visit to Meath.
"Who art thou, woman ?" said Conall.
"I am Buan, wife of Mesgedra the King." "Thou art to come with me," then said Conall.
"Who hath commanded this ?" said Buan.
"Mesgedra the King," said Conall.
"By what token dost thou lay these commands upon me ?" "Behold his chariot and his horses," said Conall.
"He gives rich gifts to many a man," answered the Queen.
Then Conall showed her the head of her husband.
"This is my token," said he.
"It is enough," said Buan.

"But give me leave to bewail him ere I go into captivity." Then Buan rose up in her chariot and raised for Mesgedra a keen of sorrow so loud and piercing that her heart broke with it, and she fell backwards on the road and died.
Conall Cearnach then buried her there, and laid the head of her husband by her side; and the fair hazel tree that grew from her grave by the fords of Clane was called Coll Buana, or the Hazel Tree of Buan.
But ere Conall buried the head of Mesgedra he caused the brain to be taken out and mixed with lime to make a bullet for a sling, for so it was customary to do when a great warrior had been killed; and the brain-balls thus made were accounted to be the deadliest of missiles.
So when Leinster had been harried and plundered and its king and queen thus slain, the Ulstermen drew northward again, and the brain-ball was laid up in the Dun of King Conor at Emania.
Years afterwards it happened that the Wolf of Connacht, namely Ket, son of Maga, came disguised within the borders of Ulster in search of prey, and he entered the palace precincts of Conor in Emania.

There he saw two jesters of the King, who had gotten the brain-ball from the shelf where it lay, and were rolling it about the courtyard.

Ket knew it for what it was, and put it out of sight of the jesters and took it away with him while they made search for it.
