In this way, they do not correspond directly to other pantheons such as those of the Greeks or Romans. The mother of the Tuatha Dé Danann is generally considered to be Anu or Danu. A number of the goddesses are associated with sacred sites where seasonal festivals are held. They include Macha of Eamhain Mhacha, Carman, and Tailtiu, among others. Warrior Goddesses are often depicted as a triad, and connected with sovereignty and sacred animals. The animals may be associated with carnage, such as wolves and crows, or the abundance of the land, such as cattle. They guard the battlefield and those who do battle, and according to the stories in the "Táin Bó Cúailnge", some of these goddesses may be the instigators and directors of the entire war themselves. The main goddesses of battle are The Morrígan, Macha, and Badb. Other warrior women are seen in the role of training warriors in the Fianna bands, such as Liath Luachra, one of the women who trained the hero Fionn mac Cumhaill. The Irish Gods are divided into four main groups. Group one encompasses the older gods of Gaul and Britain. The second group is the main focus of much of the mythology and surrounds the native Irish gods with their homes in burial mounds (The Great Barrows of the Dead). The third group are the gods that dwell in the sea and the fourth group includes stories of the Otherworld. The gods that appear most often are Dagda and Lug. Some scholars have argued that the stories of these gods align with the Greek stories and gods. Druids were held in high esteem by the community as religious leaders, teachers, and skilled members of various professions. Heroes in Irish mythology can be found in two distinct groups. There is the lawful hero who exists within the boundaries of the community, protecting their people from outsiders. Within the kin-group or "túath ", heroes are human and gods are not. The Fianna warrior bands are seen as outsiders, connected with the wilderness, youth, and liminal states. They are considered outsiders who protect the community from other outsiders; though they may winter with a settled community, they spend the summers living wild, training adolescents and providing a space for war-damaged veterans. They live under the authority of their own leaders, or may be somewhat anarchic, and may follow other deities or spirits than the settled communities.
