Input: Question: Does the queen of Connachta have any children? Passage:The Ulster Cycle stories are set in and around the reign of King Conchobar mac Nessa, who rules the Ulaid from Emain Macha (now Navan Fort near Armagh). The most prominent hero of the cycle is Conchobar's nephew, Cú Chulainn. The Ulaid are most often in conflict with the Connachta, led by their queen, Medb, her husband, Ailill, and their ally Fergus mac Róich, a former king of the Ulaid in exile. The longest and most important story of the cycle is the Táin Bó Cúailnge or Cattle Raid of Cooley, in which Medb raises an enormous army to invade the Cooley peninsula and steal the Ulaid's prize bull, Donn Cúailnge, opposed only by the seventeen-year-old Cú Chulainn. In the Mayo Táin, the Táin Bó Flidhais it is a white cow known as the 'Maol' that is the object of desire, for she can give enough milk at one milking to feed an army. Perhaps the best known story is the tragedy of Deirdre, source of plays by W. B. Yeats and J. M. Synge. Other stories tell of the births, courtships and deaths of the characters and of the conflicts between them.
