A Harbinger's Tale

I am just a normal guy with a bad job. When God came to me and offered the job, I couldn’t imagine what it would entail. My dead friends are ghosts who harass me, my best friend is the Supreme Entity and I get killed more times than I should. The job sucks but the reward is well worth it. I am the Harbinger of Doom, The Bringer of the Apocalypse and I will do what I have to do to get the job done. Come watch me save the world and destroy all of mankind. Sorry, but yes, it's going to suck to be you.
