I just finished reading this novella and had to start drawing.
The story takes place millions of years into mankind's future, long after the sun goes dark. Humanity lives in a seven mile high tower called The Last Redoubt, besieged there by the countless monsters, giants, behemoths, and unnamed horrors that lurk in the night. Travel outside the redoubt is almost always a death sentence; anyone doing so is either a fool or a hero. Here, the protagonist of the story makes his way through the smoke stacks and lava fields. His only protection is stealth, his cleverly made armor, and his Diskos, a spinning axe blade charged with earth current that both slashes and stuns. The light in the far distance comes from the redoubt, the only safe place in the world.
