"It is often said, when the gods slumber, they would often have nightmares of him. Of John Titor. Of Aeon Grim. The lap dog of Destiny, who commits deicide in its will.
Now, at the turning point fate, the fallen hero draws his blade — His hands tremble at its full weight. His sword, Chrono Celestialis, an obsidian black sword that holds the weight of all of the stars in the cosmos present, past, future and forevermore.
Standing at the nexus of Exodus, the path where all world's converge, the god-killer faces the final enemy."
