Mr. Ruin

Your mind is the battle field.  Ex-marine Ritry was a hero once, the greatest mind-diver in the Arctic War. Now he's a washed-up drunk in a neon-lit slum, trying to piece together the shards of his broken mind.  Then he meets Mr. Ruin, a shadowy figure who wants only one thing from Ritry: his soul. And he'll dive into the hellish fires of his mind to get it.
