“Night Plague”
After being killed again, Gravestone goes to hell, where he fights demons and meets Charon. He also releases a demon that feeds off blood and bioforce, and spreads like a disease. The demon is currently possessing Melissa Grant, the only survivor of the Brinkston disaster. Eternity Man is alerted to the threat, and he and Gravestone work together to try and stop the night plague. But before they can contain it, the demon infects the dead, causing them to live again.
