Cinderworld Postman

The world was never destroyed, only burned. The postman is not a profession. He is the last gravekeeper, trust keeper and game-breaker in the old world. All ashes, mist, deformed monsters, human separatists, and relics of old civilizations all come from a man-made plan to burn the world. The protagonist sends letters throughout his life, and what he sends is not longing, but the key to restarting the world, the breaking point of the thousand-year cycle, and the corrector of the fate of all lives.
