In the 2050s era of Shadowrun, Berlin is under something called the "Flux State". What exactly is this?
The video game Shadowrun Returns: Dragonfall features it prominently and refers to it as an "anarchist experiment" or something. However, there is apparently something more to it, since one character contrasts it with a lawless region saying that it's "anarchy, but without the stability of the Flux State".
What exactly is the Flux State? What is its relationship to anarchy and how does it provide a stable society?
