All you know in advance is something about the molten ingredients of the climax, which could include the following:
- Economic distress, with public debt in default, entitlement trust funds in bankruptcy, mounting poverty and unemployment, trade wars, collapsing financial markets, and hyperinflation (or deflation)
- Social distress, with violence fueled by class, race nativism, or religion and abetted by armed gangs, underground militias, and mercenaries hired by walled communities
- Cultural distress, with the media plunging into a dizzying decay, and a decency backlash in favor of state censorship
- Technological distress, with cryptoanarchy, high-tech oligarchy, and biogenetic chaos
- Ecological distress, with atmospheric damage, energy or water shortages, and new diseases
- Political distress, with institutional collapse, open tax revolts, one-party hegemony, major constitutional change, secessionism, authoritarianism, and altered national borders
- Military distress, with war against terrorists or foreign regimes equipped with weapons of mass destruction
