Humanity’s last war began centuries before the enemy was born.

Astronomer Randolph Keynes was at his observatory when the night sky tore open and Earth died. Without warning, impossible weapons descended from orbit, reducing entire cities to radioactive ruins in a matter of hours. Governments collapsed. Billions burned. The survivors fled underground into overcrowded tunnels where starvation, violence, and despair became the last remaining truths of human civilization.

Then came the discovery that shattered what little hope remained.

The attack did not come from a nearby empire or alien fleet. It originated from a distant star system hundreds of light-years away—and hundreds of years in the future.

Driven by rage and terror, humanity abandons every moral restraint in pursuit of survival. Democracies become militarized regimes. Resources are stripped from the weak and poured into a single monstrous objective: the construction of a near light-speed armada capable of reaching the future enemy before the attack can ever occur. Entire generations are sacrificed to the war machine. Poverty, suffering, and death are dismissed as necessary calculations in the name of vengeance.

Because if humanity succeeds, the future war will never happen.

No harm. No foul.

But as Randolph watches civilization transform into a cold and merciless engine of temporal warfare, he begins to question whether humanity is truly preventing extinction—or ensuring it deserves extinction. In a universe ruled by fear, revenge, and paradox, survival may demand becoming more monstrous than the enemy itself.
