a, the slow and encumbered hero met a beautiful young woman, whom he desired. However he was impotent due to his weight and unsightly appearance.
The girl mocked and attacked him. She was the daughter of Indech, son of De Domnann, one of three Fomorian kings. The young woman had hurled him so that his rump sank to the hollow of the ground. Mocking Dagda, the woman told him to carry her to her father's house, on his back.
She struck and mocked him each time Dagda refused to carry her on his back. Finally, the content of his belly emptied into the hole in the ground. With Dagda gaining his appearance, he seduced the Fomorian woman. Dagda became her lover.
The girl then told Dagda not to confront the Fomorians, but he refused to be discouraged each time. Finally, the young woman told her lover that she would use her own magic to hinder the Fomorians.
Though the Tuatha Dé Danann were oppressed by Bres' misrule and the Fomorian heavy tributes, they were still uncertain of Nuada Airgetlám's (Nuada of the Silver Hand) fitness to rule, since right arm was made of silver.
Miach, the son of Dian Cécht, proved to be an even greater healer than his father ever was. With his healing magic and his sister's assistance (Airmed), Miach was able to restore Nuada's real hand, after three days and three nights. Dian Cécht was upset and jealous of his son's skill in healing. Dian Cécht struck three times on his son's head; each time Miach was able to heal himself. The fourth time that Dian Cécht had struck his son, he had cut out his son's brain so that Miach died.
Dian Cécht buried his son and magical herbs grew from Miach's grave. Dian Cécht's daughter, Airmed attempted to categorise the herbs according to their properties, but his jealousy of his children's healing skills, caused Dian Cécht disrupted Airmed's analysis of the herbs.
With Nuada's hand restored, the Tuatha Dé Danann were now fully supporting Nuada.
Nuada and other Danann did not want to risk Lugh in battle. They feared for the young man safety, so Nuada sent for Lugh's nine foster fathers to prevent Lugh from fighting.
In the Fomorian camp, the kings sent an assassin to kill Goibhniu. The assassin was named Ruadan, the son of Bres and Brig (Brigit). Though Ruadan managed to wound the smith with the spear, Goibhniu pulled out the bloody spear and killed the young assassin. When Brig found her dead son, for the first time in Ireland, the keening was heard as she lament her son's death.
With all the fighting men gathered, the battle again took place in Magh Tuiredh (Moytura). As the two armies clashed, weapons and armour were repaired by Goibhniu, Luchta and Credne, with seemingly effortless ease. The pigskin was used to heal the wounded, while the magic cauldron fed the Danann host.
Many Tuatha Dé Danann were killed by Balor's deadly eye, including the Danann king, Nuada of the Silver Hand and his consort, Macha. Caitlin, Balor's buck-toothed wife, wounded Dagda, but according to the Lebor Gabala, Dagda had died from his wound. Ogma was also said to have die in the Lebor Gabala Ogma and Indech (or Tethra), another Fomorian king, killed one another, but Cath Mag Tuired say that Ogma was also alive. Ogma won the sword of Indech – Orna.
However, Balor could not keep his eye opened for very long, before the Fomorian grew tired. As Balor's eye gradually closed, Lugh hurled a stone from his sling, at Balor's eye. Lugh fulfilled prophecy, by killing his grandfather.
Some Fomorians managed to escape steal Dagda's harp, Úaithne. Dagda, Ogma and Lugh pursued the Fomorians. The Fomorians hanged the harp on the wall in Bres' banqueting hall.
Dagda sang to Úaithne to come to him. The harp flew from the wall and into his hand, killing nine Fomorians in its flight.
There were more fighting in which Elatha, the last Fomorian king was killed. The Fomorian army was crushed; their powers were forever broken.
The Tuatha Dé Danann had captured Bres, the former king of Ireland. Lugh only agreed to spare Bres, if Bres tell them when to plant and harvest the crops in the year. This is because Bres wa
