Cormac Cond Longas

Cormac Cond Longas appears within the narrative world of the Ulster Cycle. He is presented as the eldest son of Conchobar mac Nessa, with sources naming either Clothru or Ness as his mother. Following the Deirdre affair, Cormac was fostered by Fergus mac Róich and followed Fergus into exile in Connacht. There he entered the service of Ailill and Medb and fought for Connacht against his native Ulster in the central epic Táin Bó Cuailnge (Cattle Raid of Cooley). After the events of the Táin and the death of Conchobar, the Ulstermen asked Cormac to return to Ulster as their king, but he was killed on his homeward journey after being compelled to break his geasa (taboos) when the hostel in which he and his men were staying was raided.

The supplied sources provide no physical description of Cormac Cond Longas. He is characterized through social markers and roles: as an aristocratic prince (the epithet glossed 'Exiled Prince'), eldest son or royal scion of Conchobar mac Nessa in some accounts, and as a foster-son of the warrior Fergus mac Róich. His depiction in the narrative is thus built from titles, kinship, fosterage ties, and martial status rather than bodily detail.

Cormac's capabilities in the sources are those of a high-status human warrior and potential ruler rather than supernatural powers. He fought prominently in the Táin Bó Cuailnge on behalf of Connacht, and is explicitly recorded as having restrained Fergus mac Róich from killing Conchobar, showing decisive agency and martial authority. Politically, he was recognized by the Ulstermen as a legitimate successor after Conchobar's death, being asked to return as king. The sources do not attribute any magical or otherworldly abilities to him; his strengths are social legitimacy, fosterage loyalties, leadership potential, and combat skill.
