Kernunnos is the Celtic god of the Underworld. A sinister figure, he was violently opposed to the Druids and their teachings. He employed a powerful Half-god enforcer, Morrigan, who terrorized the people of Eire and worked to hunt down the druids. Kernunnos was in fact victimizing Morrigan: he kept her dependent on drinking his blood, which had a powerful narcotic effect, and he held their daughter Brigid hostage.
