When iron armor became the pen and blood became the ink, they used their humble bodies to write down the mountains and rivers, from the mire to the sky. He doesn't ask for a title, and she doesn't ask for a way home. Only each other is the only unquenchable fire in troubled times. Destiny is called destiny, but they insist on using bones as ladders and hatred as blades to tear apart this man-eating world.
