I discovered something interesting about the mythology of my Viking ancestors. On the eve of Ragnarök, there was a brutal winter that lasted three grueling years. This winter was called the Fimbulwinter, which means “Great Winter” in Norse. It caused a massive loss of life and was followed by countless wars. After these wars were finally over, the Twilight of the Gods began and the world was remade forever. I am thinking of including a similar winter in my spin-off fantasy trilogy that will set the stage for the beginning of the story.
