Faithful henchman of Lugaid mac Con who served with him through defeat, exile, and restoration of power only to abandon his king when he abdicated in favour of Cormac mac Airt. That Lugaid Lága should have earlier slain Cormac's father, Art mac Cuinn, seemed not to trouble the young king. Lugaid Lága later won great esteem at the court of Cormac and was once listed as one of the five great warriors of Ireland, along with Cúchulainn, Lug Lámfhota, Conall Cearnach, and Fionn mac Cumhaill. A brother of Ailill Aulomm, he is much associated with the Glen of Aherlow, Co. Tipperary. Lugaid was the protector of Uirne, the mother of Bran (2) and Sceolang, after she returned to human form. Modern commentators have suggested his characterization is a local Munster adaptation of Lugaid mac Con. Once thought to be the father of Fenian warrior Mac Lughach.
