A magical portal to the Plane of Fire disappears into the sun just after creatures exit it for the first time in recorded history. An overwhelming telepathic burst from within the sun quickly follows, and a scientist recruits the heroes to help her find out what's going on. The mission takes the heroes to the Burning Archipelago, a bubble city in the sun's atmosphere, and Asanatown, the lashunta enclave there, to meet with another scientist who can help. Before that meeting can happen, however, the recent 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. Trapped, the heroes must rescue their contact and return power to the proper authorities to escape!
