Scorned as a witch, a young woman with powers leaves her village to start a new life — just as a ruthless army scours the countryside for her kind.

Shaken and alone, Nimue presses ahead on her quest, as flashbacks reveal a harrowing encounter years ago that changed the course of her life.

While Nimue, Morgana and Kaze seek refuge in an ancient web of tunnels, Arthur and Gawain fend off a siege led by the Weeping Monk.

Nimue weighs a fateful decision, Uther takes a defiant step, and Gawain discovers not all is what it seems within the Red Paladin camp.

With the future of the Fey hanging in the balance and enemies closing in from all sides, Nimue sets in motion the final pieces of her plan.
