The Morrígan
The Morrígan was said to take on the form of a red-furred wolf, particularly in her battle with the hero Cú Chulainn. Mac Cecht killed a wolf feeding on a still-living woman on a battlefield. Cormac mac Airt was said to have been raised by wolves, and that he could understand their speech. Four wolves would accompany him in his rebellion against Lugaid mac Con, and he would later be accompanied by them until the end of his life.
