Jzadirune was a gnomish enclave located beneath the city of Cauldron. It was (and still is) decorated with many illusions, both grand and subtle, and was renowned in Cauldron and beyond for its wondrous magic items. Those same magic items, however, were to be the enclave’s undoing. About seventy years ago, Jzadirune fell under the influence of a strange curse called the Vanishing. Those afflicted would become pale and weak, and eventually fade away into nothingness. It was soon discovered that the Vanishing was somehow connected to the magic items fabricated in Jzadirune. Rather than face the prospects of losing any more people, the gnomes abandoned Jzadirune and destroyed (almost) all their cursed magic items.
Many decades later, Jzadirune became home to a group of dark ones, who forged an agreement with the hobgoblin slavers led by Kazmojen, in the Malachite Fortress below. The dark ones would kidnap people and bring them to Kazmojen, who would then sell them to the highest bidder. Kazmojen and the dark ones were eventually foiled by a group of adventurers who entered Jzadirune in search of orphans kidnapped from the Lantern Street Orphanage.
