Morrigan
Morrigan is sometimes called Morrigu. She was an Irish goddess of death on the battlefield. She helped the Tuatha De Danann at both battles of Magh Tuireadh. She was also associated with the other war deities: Macha, Badb, and Nemain. Her favorite form to turn into, was that of a crow and as such she settled in triumph and revenge on the shoulder of the Ulster hero Cuchulainn, when he was killed in the war against Queen Medb's forces. Not only had he refused Morrigan's love, but in anger had even wounded her.
Dian Cecht
Dian Cecht was the Irish god of healing. It's said that he and his daughter Airmid, tended the spring whose waters could restore the dying gods back to life. After the leader of Tuatha De Danann, Nuada, lost his hand fighting in the first battle Magh Tuireadh, Dian Cecht gave him a silver hand, earning him the title, Nuada of the Silver Hand. Even though the Tuatha De Danann were highly impressed by the god's handiwork, they felt that perhaps Nuada was no longer physically able to be their war leader. That was when Bres, who was half Fomorii, took his place. He turned out to be a tyrant and became very unpopular with the Tuatha De Danann. They then decided to restore Nuada to leadership, after Miach, the son of Dian Cecht, had made him a new hand of flesh and blood. Unfortunately, the god of healing became jealous of his son's medical skills and killed him.
Dylan
Dylan was the Welsh sea god. His parents were Arianrhod and her brother, Gwydion. Soon after he was born, he went straight to the sea and jumped in. Immediately Dylan could swam just as well as the fish. It's said that when his uncle, the smith god Govannon, killed him, all the waves of Britain and Ireland mourned his death.
Cliodhna
Cliodhna of Irish mythology, was one of the otherworld goddesses of beauty. It was said that she possessed three very fine, magical birds which could sweetly sing the sick into a deep sleep and cure them. The goddess was passionately in love with a mortal man named Ciabhan, a youth with curling locks of hair. One day, when Ciabhan was hunting and Cliodhna was walking along the shore near Cork, the sea god Manannan Mac Lir put her into a magic sleep and then sent a wave, which pulled her back to the Land of Promise.
The Fianna
The Fianna were the famous warriors responsible for the safety of the High King of Ireland. They were frequently called the Fenians and their leader was Finn Maccool. Most of them came from one of two clans, the Bascna and the Morna. Many of their exploits are related in the tales of the Knights of the Round Table. To join, "no man was taken till the gound a hole had been made, such as would reach the waist, and he put into it with his shield and a forarm's length of hazel stick. Then must nine warriors, having nine spears, with a ten furrows' width between them and him, assail him and let fly at him. If he sustained injury, he was not received into the band."
Caer
Caer was a beautiful fairy maiden, who was loved by the Irish love god, Aonghus. Her father Ethal was one of the Tuatha De Danann. The love god saw Caer in a dream and was so attracted to her beauty, that he fell into a deep sickness. When he discovered who Caer was, he immediately asked her father for her hand in marriage. Ethal however, stated that it was not in his power to grant this because his daughter had taken on the form of a swan. Ethal told Aonghus that he could ask Caer to marriy him only if he was able to recognize her from among the large flock of swans with whom she lived. When the swans arrived at the Lake of the Dragon's Mouth, the love god immediately recognized Caer and called out her name. Later Aonghus and Caer were married.
