Elminster Must Die! — Ed Greenwood

When the goddess of magic was murdered, Elminster's world shattered. Once the most powerful wizard in the world, immortal, beloved of the goddess of magic, and the bane of villainy, he is now a tired old man. He is powerful but mortal, and with all the enemies a man who makes a habit of saving the world tends to accumulate. To make matters worse, Elminster has needs -- feeding powerful magic items to the Simbul, his lover, is the only thing that keeps her sane -- but their increasingly risky collection leads his enemies right to him.
