From the back cover:

"It's war! The long-standing dispute between the Celestial Order Wizards and the Mages of the Red Cabal erupts into open warfare as the two rival factions try to retrieve pieces of an artifact before it's too late. At last it happens - one of the Celestial Order's highest-ranking mages is slain in a surprise attack by the Cabal. Or is he? It's up to you to penetrate the enemy's hidden base, find Archael and his famous wand, and bring them back to safety."
