The demon Zdim was happy with his philosophy on the Twelfth Plane, until he was conjured to Prime Plane to serve the human wizard Maldivius. There, to a logical fiend, men seemed wholly irrational. He was ordered to eat the first being to enter a sanctum, then beaten for devouring the wizard's apprentice, who sneaked through the doorway. Prime Planers stole, lied, and fought each other in needless wars. Naturally, a totally logical demon couldn't understand them. And inevitably, Zdim made mistakes. But when war came to the city of Ir, only Zdim could escape to seek rescue from wild soldiers and uncertain sorcerers. The role of savior should have gone to a hero out of the legends. But there was only one Zdim—and he was fallible.
