From the Magnum Opus on the 2009 PDF edition:

The year is 999, and in the night skies above Legend the lights of the Five Magi circle—not comets but the ancient wizard-kings of Krarth, banished centuries ago, waiting for the turn of the millennium to return to the world they once controlled.

Altor, a young warrior-monk returning to his abbey, finds himself ambushed by werewolves and charged with a dying man's quest. He must reunite the pieces of the Sword of Life, supposed to be the only thing that could stop the Magi's return. But first he must forge an unlikely alliance with the charming rogue Caelestis, and descend into the terrifying Battlepits of Krarth, an awesome gauntlet of combat and sorcery, to win the favour of a modern-day magus. But in the massive labyrinth, where nothing is as it seems, can they trust anyone—even each other?

Based on the classic Bloodsword series of gamebooks, the Chronicles of the Magi trilogy is a fantastic adventure through the Lands of Legend, the setting for the Dragon Warriors RPG. Each book is a great read, but also contains background, trivia and colourful characters from Legend that any Gamesmaster will find easy to weave into their campaigns.
