The Drowning of Oceans

After Sam says yes to Lucifer- things seem to go sideways for the world. A virus soon breaks out and the world is left to the mercy of monsters and unruly men. Worst of all there's no more balance. Heavenly hosts have all but disappeared. No one is listening to prayers and pleas... And all that's left is a small group of people that are left behind. All of which look up to the one and only Dean Winchester, whom never thought he could be a leader. But seems to be the only thing standing between total extinction of humans.

(Title inspired by the book 'Milk and Honey'. This is basically a detailed series of events in the end verse.)
