Military action
The Gods strike against the spawn of Khyber, to further their war efforts they create the perfect soldiers, the Titans. The war lasts for millennia.
The Gods react to the surge of demons, they send their angels to do battle against them, but the angels are finite. To fill their ranks the Gods make the first living beings: the Titans. The Smith forges their bodies; the Traveler animates them; the Scholar gives them sentience; and the Solar bestows a piece of himself to each titan, a soul. The Mother finishes the task by breathing life into them and nurturing the newborn Titans, her counterpart the Reaper is tasked with collecting their souls when they fell in battle to return them to Syberis.
