The war against the Calamities had finally come to an end and the world was on the precipice of a new era. In the span of a single day, several revelations were made creating a storm among the public who didn't even get the chance to celebrate the end of a decade-long grueling conflict.
First, they hear that Odin, the man who's said to be humanity's savior, was in fact a fake who only cared about his goals. As if that wasn't enough of a bombshell, they then learned that the multiverse was real and that there are countless worlds out there some far more advanced than theirs. The Nephilim were the residents of one such worlds and they were able to wreak havoc on the humans without having to carry the carnage themselves. The only way to stop them was to receive help from the same otherworldly race, which led to another groundbreaking revelation; the Valkyries were sentient beings.
