In the imaginary land of Prydain, where "evil is never distant," Prince Gwydion faces dangers more threatening than have ever been dreamed of. It has become imperative that the Black Cauldron, chief implement of the evil powers of Arawn, lord of the Land of Death, be destroyed.
For each of the warriors chosen to journey to Arawn's domain, the quest has special meaning. To Ellidyr, the youngest son of an impoverished king, it means a chance to satisfy his bitter longing for fame. For Adaon, beloved for his gentleness and bravery, the quest is an omen whose significance he dreads to discover. And to Tara, Assistant Pig-Keeper, the adventure seems a glorious opportunity to wear his first sword, and be a man among men.
In this story, filled with great sacrifice and great adventure, each warrior fulfills his destiny in ways entirely unforeseen.
