The final rift was closed and the Hell War was over at last. The citizens of the Earth celebrated for the first time in almost six years. The forces of Hell had been beaten. Humanity had won. Now began the long process of burrying the dead and rebuilding, but the nations of Earth were united now, and they were willing to work together to usher in a golden age of peace.However, all was not as well as it had seemed, for six months later, more Hellspawn began to appear and the air was once again heavy with cries of pain and screams of death.
