Merlin ‘The Eye of the Phoenix’
Morgause (Emilia Fox) is the half-sister of Morgana, a skilled warrior, a powerful sorceress and a High Priestess of the Old Religion.
In the episode ‘The Eye of the Phoenix’ Morgause enters Camelot in the disguise of an old beggar woman to meet her sister. She gives Morgana a phoenix eye and tells her to give to Arthur to wear as a charm in a bracelet – but rather than protect him the charm will absorb his life force causing his death and allowing Morgana to take his place as heir to the throne.
Fortunately Gaius and Merlin become suspicious.
