Priestess (Ring Theory)
From Tardis Wiki, the free Doctor Who reference
Among the memories within the Gestalt of which Kady Williams saw glimpses as the Gestalt's host were images of a red-headed, veiled priestess. In some visions, others around her bowed down to her, while in others, Kady saw the priestess being placed on trial. Kady believed that the priestess may have been the being who would go on to become the Gestalt, although she thought it equally plausible that she was merely one of the Gestalt's earliest hosts. The Gestalt, cagey about their origins, refused to confirm either way. (PROSE: Ring Theory)
