Summary:

Vermithrax, the last of dragonkind, swooped down over the kingdom of Urland, let loose a torrent of flames, and reduced everything to smoldering ash. Then, finding the newly blackened wasteland much to its liking, it settled in for a long stay.

Desperate, the villagers finally sought the help of Ulrich, the last living sorcerer. But Ulrich was too old, too feeble. That left only Galen to go against the might and terror of the deadly dragon. Of the use of weapons he knew nothing. He was merely a sorcerer's apprentice, and of the Old Magic he knew very little.
