In Avalon, the time before King Arthur was the time of three women who altered the fortunes of Roman Britain by reclaiming the magic and traditions of their land. Caillean, a young priestess, rescued and raised an orphaned Gawen. Dierna used wisdom and love to guide Avalon and veiled the island from a hostile world. Viviane, the Lady of the Lake, prepared Avalon for the coming of a legendary king.
