Hercules: The Legendary Journeys - S05E03 - Resurrection

Bronagh, leader of the Celts on the island of Eire, told Hercules he was their “”Chosen One”” — chosen to lead the Celts to freedom. But the gods of Eire didn’t like the Celts worshipping Druids, so they sent Morrigan, a demigod assasin, to destroy the Druids. However, when she killed the Druid guardian of justice, she unwittingly took his place. Hercules, who finally stopped blaming himself for Iolaus’ death, defeated Morrigan in battle, but the Druids explained that if she died, the spirit of justice would die with her. They disappeared, leaving Hercules to care for Morrigan.
