The King's Children, Signy, Regin and Buri, are forced to flee from their home when their father is killed by the marauding chieftain Harwolf and his men. Behind the high mountains, somewhere to the East, there is a strange kingdom where they hope to find help avenging their father and winning back their homeland. Along the way, they discover a world inhabited by witches, elves, the undead, giants and many more strange and wonderful creatures. The royal children will need all their courage and determination to make it – and most importantly, they must learn to trust one another and stick together.
