Closing Song

In the first hundred years after the disaster, the crack in the sky was no longer a vague legend told by the old, but a bloody nightmare that hung over human heads and lingered all year round. Those cracks are scattered in every corner of the world, with different shapes but equally ferocious - some are like giant pythons hovering over the ruins of the city. Black-red mist continuously overflows from the cracks, filtering the sunlight into a turbid dark yellow, making the day as oppressive as dusk.
