As a young man Lugh travels to Tara to join the court of king Nuada of the Tuatha Dé Danann. The doorkeeper will not let him in unless he has a skill with which to serve the king. He offers his services as a wright, a smith, a champion, a swordsman, a harpist, a hero, a poet and historian, a sorcerer, and a craftsman, but each time is rejected as the Tuatha Dé Danann already have someone with that skill.

Lugh is given command over the Tuatha Dé Danann, and he begins making preparations for war, A war in which Lugh kills his grandfather Balor.
Tailtiu or Tailltiu and earth goddess was the wife of Eochaid mac Eirc, last Fir Bolg High King of Ireland, who named his capital after her (Telltown, also known as Taillten between Navan and Kells). She survived the invasion of the Tuatha Dé Danann and became the foster mother of Lugh.
Tailtiu is said to have died of exhaustion after clearing the plains of Ireland for agriculture. Lugh established a harvest festival and funeral games, Áenach Tailteann, in her honour, which continued to be celebrated as late as the 18th century.
The first Áenach Tailteann, later the Taillten Fair, was held at Telltown. Historically, the Áenach Tailteann was a time for contests of strength and skill, and a favored time for contracting marriages and winter lodgings. A peace was declared at the festival, and religious celebrations were also held. Aspects of the festival survive in the celebrations of Lughnasadh, and were revived as the Telltown Games for a period in the twentieth century.
