The mission takes the heroes to a lashunta enclave called Asanatown in the Burning Archipelago, a bubble-city in the sun’s atmosphere, to meet with another scientist who can help. Before that meeting can happen, however, the psychic disturbance leads radicals among the telepathically sensitive lashuntas to take matters into their own hands, closing Asanatown off from the rest of the sun-based city.
