Lamp of Truth

The Lamp of Truth lands the little company on the elemental plane of air, where they tangle with several warring tribes of jinni and other air elementals. They cannot pass the next Portal till they succeed in "healing the harms of this land," a task which involves them with political intrigue, corruption in the highest echelons of elemental society, and a vase whose dwimmer permits its owner to generate an army of automatons.
