The surface is a frozen wasteland, where sub-zero temperatures make survival nearly impossible. Ancient technological remnants lie buried beneath endless ice, hoarded by those with power to control them.

As they uncover a colossal power struggle among Gods and legends, father and son must overcome their conflicts to navigate the realm's hidden secrets and confront the overwhelming forces that govern the world below.
