In 2027, Mexico City has drained its aquifers, choked its air with smog, and fallen under corrupt, violent police rule. The city is a concrete test case of a metropolis that outgrew its water base and turned environmental exhaustion into social and moral collapse.
Aztec cosmology holds that the world has been created and destroyed four times, each era or 'Sun' ending by a specific force: jaguars, wind, a rain of fire, and flood. The current, fifth Sun, Nahui Ollin ('4 Movement'), is fated to end in earthquakes. Time is a series of finite ages that each carry the element of their own destruction, not an open line of progress.
Aridjis overlays a myth of predestined world-ending onto a disaster that people made themselves, such as aquifer depletion and pollution. Seeing it this way shows two things. Ancient apocalyptic frames can make modern environmental ruin feel meaningful, and the same framing can breed fatalism, so a society stops correcting damage it believes was always destined.
The novel argues that environmental collapse and authoritarian corruption feed each other. As water and clean air grow scarce, whoever controls the survival resources gains power, and the rulers who profit from that scarcity have no reason to reverse the degradation. The ecological crisis becomes a governance crisis, and the corrupt governance speeds up the ecological one.
