The Oblivion Project

In the year 3744, a great war broke out between Heaven and Hell. Earth, on the brink of destruction, at last used nuclear weapons upon the two dimensions as a final resort to save what was left of the planet. However, in the end, the Hell dimension imploded, destroying a vast chunk of the Earth, and the Heaven dimension collapsed out of the sky, and hit the Earth as a storm of ash and rock. The oceans were filled with ash, and the crust of the broken planet fractured from the impact. This was the Aftermath.
