As a young dragonlord, Ged, whose use-name is Sparrowhawk, is sent to the island of Roke to learn the true way of magic. A natural magician, Ged becomes an Archmage and helps the High Priestess Tenar escape from the labyrinth of darkness. But as the years pass, true magic and ancient ways are forced to submit to the powers of evil and death.
