In the beginning, there were 12 beings that rose from the void, who shared their power to create Traum and lived peacefully amongst their descendants. All was harmonious, and the descendants prospered under the blessings of the 12 beings who were now worshipped as gods. But one day, an unexpected 13th being, Evil God Serpens, creeped out from the shadows of the 12 Gods.
To stop Evil God Serpens from disrupting the balance of the world and corrupting their descendants into darkness, the 12 Gods shared Runes and Essences, infused by their powers, with their descendants in order to smite down evil. Unfortunately, their efforts failed. In the end, the 12 Gods agreed to join as one and revert back to the void, along with Serpens.
After the clash, Serpens's soul was split into two and scattered across the world. The 12 Gods ended up losing their flesh, along with their names, as they fell into eternal slumber. As everything began with the birth of the 12 Gods, and Serpens originated from the 12 Gods, it was certain that Serpens would never recover its powers without a new beginning.
But as time went by, the descendants of Traum, once against, began utilizing the powers of Runes. This advancement eventually led them to the Zodiacs that could reawaken the Gods. Thus, they decided to summon the 12 Gods back into the world by creating figures from connecting the stars and calling out their names.
