Monsters: Evolving from Titans to Ancient Gods

This was the era before mythology was recorded. Titans roamed the earth, monsters wreaked havoc, and extraterrestrial races lurked in the shadows. Humanity was merely a bystander. Luneburg awakened in a Neolithic tribe, possessing the body of a Titan, and descended upon the dawn of mythology. In Eastern mythology, he was Kuafu, chasing the sun and drinking from the river; Luneburg, the giant carrying mountains on his back. In Greek mythology, he was Tartarus, the lord of the abyss, imprisoning the rebellious Titan gods. In Norse mythology, he was Odin, the one-eyed god, riding his eight-legged steed, measuring the world's boundaries with his eternal spear. Radiation that brought death caused him to evolve; with each powerful enemy defeated, his power grew stronger. When humanity began to use mythology as a compass, searching for the traces of the gods, they ultimately discovered that the templates for all legendary giants were reflections of Luneburg in the mirrors of different civilizations' legends. …Longbo wakes up to find himself reborn in the Neolithic Age, becoming a Titan born from early humans.
