Of all the enemies Thorgal has faced in his life, Kriss of Valnor is by far the fiercest. She is also one of the most ambiguous, as the mother of one of his children and someone who has committed countless unspeakable acts. Can she find redemption? Perhaps, as Kriss sacrificed herself to save not only her son Aniel, but also Thorgal's wife Aaricia. An act of selfless bravery for which she's rewarded with waking up in the kingdom of the gods. But Valhalla is not quite yet hers... She is brought before the valkyries to face up to her deeds and have her life judged by the goddess Freyja.
