Морриган
The Morrígan's earliest narrative appearances, in which she is depicted as an individual, are in stories of the Ulster Cycle, where she has an ambiguous relationship with the hero Cúchulainn. In the "Táin Bó Regamna" ("The Cattle Raid of Regamain"), Cúchulainn encounters the Morrígan, but does not recognise her, as she drives a heifer from his territory. In response to this perceived challenge, and his ignorance of her role as a sovereignty figure, he insults her. But before he can attack her she becomes a black bird on a nearby branch. Cúchulainn now knows who she is, and tells her that had he known before, they would not have parted in enmity. She notes that whatever he had done would have brought him ill luck. To his response that she cannot harm him, she delivers a series of warnings, foretelling a coming battle in which he will be killed. She tells him, "It is at the guarding of thy death that I am; and I shall be."
