This supplement for Rogue Trader serves as a compendium of the dark creatures and xenos races awaiting Explorers in their travels. In addition to its many adventure seeds and plot hooks, it features art and descriptions for a range of foes, including Shadowkith, Thornmaws, Void Krakens, daemons, and much more. Players looking for even more vile enemies will appreciate the Xenos Generator rules, which allow them to create alien species as varied and dangerous as they can imagine.
