The Pearl of the Ebon Orb: Although the title may sound like it's a fantasy game, this campaign was actually a sci-fi campaign. Superficially a post-apocalyptic setting, the game was intended to explore three separate models of future society.
The first nation is the Bunker: a militaristic remnant made up of various old nations' armies and their descendants, scrabbling for survival and striving to reinvent key former technologies amidst the wasteland. Its drive to survive internal and external tensions puts it in opposition to the Oval City.
The second nation is the Oval City, a genetically advanced sterile subspecies of human, made up of biological females conceived through ovular parthenogenesis. Each individual has the collected memories of her ancestors deep within her psyche, and can reactivate them for guidance by dreaming with narcotic stimuli. This nation represents technological stasis as a conscious societal choice: no new technologies have been developed for centuries, and no new citizens are born unless and until an existing citizen dies, whereupon her eggs are harvested and her brain matter is incorporated into the newborn.
The third and final nation - the Elevated - is a genetically human, but technologically very advanced faction comprised of outright clones led by a War survivor. This society represents strict devout devotion to technology, in a quasi-religious hierarchy with the highest scientists commanding priestlike faith among their subordinates. The nation is based onboard a space elevator at coordinates (0,0) off the coast of old Africa, but has been searching for ways to exploit the remnants of civilization on the surface. They enter the endgame of the campaign as a hostile force, small in number but with considerable technological power at their disposal.
