Humanity once ruled the world—until it underestimated what lived beside it. Cats and rabbits formed an unlikely alliance and waged a short, brutal war. Humanity lost. The cities remain, but they belong to new rulers. Skyscrapers became territories, tunnels became warrens, and human technology turned into toys and symbols of power. The victors are chaotic, unhinged, and strangely entertaining. Cats rule through intelligence and control; rabbits through speed, numbers, and sudden violence. Were humans exterminated? Officially, yes. Unofficially, rumors persist of sealed cities, underground zones, and a forgotten species still breathing in the dark. This is the world after humanity.
