Phaedra
From The Stargate Omnipedia
Cobbler's wife, member of Osric's people. Several weeks before the arrival of SG-1 she set off in search of her son, who had strayed too far from the village. Neither have been seen since that time. Many among the superstitious villagers believe a curse of Morgan Le Fay is responsible.
Phaedra and her son may have been fabrications of the leader of the Ori forces, Adria, who had been impersonating Osric at the time he mentioned the pair.
KEY EPISODE
