The Celtic Pantheon was the collective gods worshipped by the people of Eire, Britannia, Gaul and most of Western Europe. They were also known as the Tuatha de Danaan or "Children of Danu." In ancient times, they presided on Earth as the rulers of the Ancient Counties of Ulster, Leinster, Connacht and Munster in Ancient Eire until they were driven from Eire by the Milesians during the Sixth Invasion of Eire. They preside in the other-dimensional realm of Otherworld which includes the realms of Avalon, Tir Na Bog and Annwyn, the Celtic Land of the Dead among others.
Much like the Olympians, the Celtic gods often trafficked with mortals and produced half-immortal children known as Demigods. Not much is known about their origins, but according to myths, they were descended from the ancient earth-goddess Danu and the sun-god Belenus. Their son, Eochaid Ollathir (the Dagda), led the Danaans in the Fifth Invasion of Eire against the Fomore, the ancestral gods of Eire, and were victorious, but their champion, Nuadhu Airgedlamh, was not able to rule because he had lost a hand in battle. He relinquished the throne to Bres, who being half-Fomore turned Eire back to his father's relatives. The Danaans went to war once more with the Fomore and once again conquered Eire with the help of their champion, Lugh, driving the Fomore once more from Eire. It is not known how these events unfolded in the Xenaverse.
In the Xenaverse, the Celtic Gods were worshiped as gods by the Druids and the people of Eire. Arriving in Eire after the wane of the Celtic Gods, Hercules encountered the demigod Morrigan who was being sent by Kernunnos to slay and kill off the Druids. He proved to be a major opponent of Kernunnos's plans, first freeing Morrigan from his influence before defeating Kernunnos himself.
Much like the Olympian gods, the Celtic Gods were worshiped throughout the British Isles and most of Western Europe, bordered by the lands of Asgardians to the north, the Olympians to the south and the Dievans (Slavic Gods) of the East. The invading Romans adopted many of the Celtic gods into their pantheon and vice versa. The Celts knew Zeus and Hermes as Taranis and Esus and the Romans worshipped Belenus as the sun-god Helios. The Celts worshipped and honored their gods for several millennia until they were replaced with Christianity, many of their figures being replaced with human saints, such as St. Brigid, who took over their temples.
Powers and AbilitiesEdit
The Celtic Gods seem to possess many of the same superhuman Powers and Abilities of the Olympian gods, but at unknown levels. Kernunnos had several abilities on par with Hades of the Olympian gods, and Morrigan had several above-human abilities equal or on par with Hercules.
The full limitations of the Celtic gods are unrevealed. Unlike the Sumerian gods and Asgardian gods who relied on Apples of Immortality to sustain their immortality and existence, they were dependent on sacred wells to maintain their vigor and immortality, but this might not have applied in the Xenaverse.
