Wurm War

Is this the end?
Timothy and Cassandra may have beaten the evil sorcerer Alhazred, but their problems aren't over. Alhazred was so tied to the matrix of energy that his death caused a magical brownout, dimming all the sorcerous power there is, both in people and in lights. The brownout also caused a weakening in the dimensional barrier that kept the Wurm out of Arcanum. For the first time in decades the Wurm have the chance to exact their bloody vengeance upon the mages who sought to destroy them. Can Timothy and Cassandra end the feud before the Wurm devastate Arcanum?
Timothy and Cassandra have defeated the sorcerer Alhazred but in so doing have weakened the dimensional barrier which had prevented the Wurm from attacking their world.
