Told entirely from the perspective of Nimue, the Lady of the Lake, across three timelines simultaneously: her origin as a Celtic water-priestess during the Roman occupation; her long middle years watching over Excalibur and shaping events from the margins; and the aftermath of Arthur's fall, when she must decide what the next age of the world will look like. This is a slow, dreamlike series — closer to literary fiction adapted to screen than conventional fantasy. Morgana appears here as a younger woman who seeks Nimue as a teacher. Merlin appears as a former lover whose choices Nimue ultimately cannot forgive.
