Timothy and Cassandra may have beaten the evil sorcerer Alhazred, but their problems are far from over. Alhazred was connected so close to the matrix energy that his death caused a magical blow-out, dimming all the sorcerous power, both in people and in lights. The blow-out has also weakened the dimensional barrier that keeps the Wurm out of Arcanum, and for the first time in decades the Wurm have the chance to wreak their vengeance upon the mages who sought to destroy them. Can Timothy and Cassandra end the feud before the Wurm devastate Arcanum?
