It's a system Machiavelli and Heisenberg would understand, a cauldron of roiling relationships prone to entropic spasms. But its hundreds of marauding inhabitants aren't just looping drones: They're pyramid climbers whose aspirations and grievances and strengths and weaknesses evolve with or without your involvement.
