The mists of Avalon

England in a time of upheaval: The unrest from external threats posed by the Saxons is intensified by the conflict between old and new religions. A supporting force in the land is Viviane, the current Lady of the Lake. She is forging a long-term plan to bring forth a High King who will strengthen the land and the old religion once and for all: Arthur, the half-brother of her niece Morgaine, whom she sees as her worthy successor. Viviane's plan could succeed, were it not for her sister Morgaine, who is weaving her own power-hungry schemes. Avalon seems to be irrevocably sinking into the mists of time.
