Warhammer 40,000

Scattered and leaderless after their disastrous defeat at the hands of the Dark Angels, the remnants of the Night Lords fleet head to a prearranged location: the world of Sotha, on the fringes of Ultramar. They expect to find some of Guilliman's XIII Legion opposing them, but they're not prepared for what awaits them when they stumble across one of the most important worlds in Imperium Secundus.
