I am Pluton. I am the King of the Underworld. I am the literal incarnation of punishment and comeuppance. All men are sure to face me, and all men are sure to fall before me. When I walk the mortal earth, the very world is uprooted by nothing more than my breath, and the strike of my trident churns the sky and cracks the planet in twain.

And yet I have been slain by naught but a single punch. A mortal man, whose heart scarcely beat as he looked upon my unknowable visage, rended me to flesh without even trying.

I need a vacation.

Chapter 1 - A Strange Place

An impossible distance beneath the earth, in a place where time could not be measured and there was no need for names, something stirred. A crevice in the ceiling of a cavern more spacious than the sky split open, and a piece of bloody pork slipped through and fell to the floor beneath. The wet slap of the meat striking the rock echoed for miles, and a thousand creatures with neither face nor form turned as one towards the sound.
