From publisher blurb:
Initially an unfocused collection of monsters ostensibly for the Heavy Future campaign setting, The Dark Star Bestiary rapidly evolved into something more interesting. As this sourcebook’s name implies, its monsters are a collection of spacebased threats. Predators evolved in the airless, absolute zero void of deep space, elementals born in the frigid heart of a comet, and the demons of hyperspace are detailed within.
This sourcebook is also a special treat for me as an author. I finally get to revisit one of my earliest, and best received sourcebooks: Guide to the Known Galaxy (Otherverse Games, 2008), which introduced the beautiful and deadly multiversal eco-system called the Lifechain. Several iconic Lifespawn creatures are rethought, rebalanced and redesigned for use with The Pathfinder Roleplaying Game, and new Lifespawn are introduced. That makes the Dark Star Bestiary the first part in a long awaited revision of the bestselling Guide to the Known Galaxy.
