Castle of El-Hajjâj

The Castle of El-Hajjâj (later known as Nailah's Keep) was the citadel of a powerful wizard of the Rabian Planes. When the Dervish Taysir and Raghib arrive after dueling the Sorceress Queen Nailah in Bassorah, the castle was submerged by an illusionary lake that the Dervish Taysir dispelled. He and Raghib entered, fought Brass Men and a Guardian Beast, and found El-Hajjâj himself in his workshop with a City in a Bottle.
