Her Left Hand and My Right Hand

After artificial intelligence came into widespread use, extreme digital utopians conducted numerous illegal virus experiments targeting intelligent systems. This ultimately gave rise to an intelligent life-form within the internet that was almost entirely unconstrained. By the time humanity discovered it, it had already seized complete control of the world's internet resources. But human society had no international conventions to address the crisis. When it began reaching into military and political systems, several major military powers secretly agreed to launch a devastating attack on all of humanity's network and electrical infrastructure. The intelligent life-form appeared to have been completely eradicated, but the resulting social upheaval and Great Depression brought society to collapse, plunging humanity into a century-long Dark Age. Yet the intelligent life-form had not truly been destroyed. Using biotechnology, it preserved itself in another form, but split apart in the process and began tearing itself to pieces. Humanity slowly emerged from the Dark Age, and in time, several great financial conglomerates secretly took control of the entire world. When Earth's development hit a bottleneck, these conglomerates plotted a revolution on the moon. The Left Hand, once a fixture on the legendary bounty hunter rankings, had been lying low on the moon for a long time. The upheaval there left her no choice but to return to the underworld. But at the crucial moment of the revolutionary war, an unexpected accident caused every plan to fail. A new kingdom rose in the aftermath, and human history entered yet another cycle of rise and fall.
