Humanity may have settled untold worlds in the Koronus Expanse, but only the most audacious of Rogue Traders would dare claim that it asserts any true dominion over this lawless region of space. For every conquered planet there are dozens more under the control of vile aliens. Explorers operating in the Expanse are sure to encounter these threats in their journeys, either by accident or design, and must be ready lest their ship and their profits be lost.The Koronus Bestiary, a supplement for Rogue Trader, is a detailed compendium of deadly beasts, hostile xenos, unholy daemons, and other dangers that fill the uncharted regions of the Koronus Expanse. In addition to its many adventure seeds and plot hooks, this comprehensive tome features art and descriptions for a range of foes, including Shadowkith, Thornmaws, Void Krakens, and a host of others. Looking for even more vile enemies? The Xenos Generator rules allow players to create alien species as varied and dangerous as they can imagine!
