Camelot: Morgan's Exorcism

Camelot is a television series on CBC as a re-imagineing of the Arthurian mythos. Morgan (Arthur's half sister sometimes called Morgaine or Morgana la Fey in some texts/legends) is beset by some kind of supernatural illness that causes great pains, fever, hunger and tears of blood. A nun, who raised her, comes unexpectedly to her aid. It seems Morgan performed a "summoning" and this is the consequence of her actions. She seems "possessed" and the nun performs a kind of "exorcism" by placing what looks like 8 mirrors around a white circle (made of salt?) with 8 symbols (all germanic runes or bastardizations of them) that seem to summon the image of her father for her to fight. She shatters a mirror, ending her torment.
