From publisher blurb: The Helriven are a new playable science-fantasy race of crab-like humanoids who bargained with the darkest forces for power. Ceaseless in their violence, sparse in their words, and now wholly dedicated to the extermination of all other races, these strange asteroidian creatures have set entire systems afire, leaving the galaxy terrified that their world may be the next they levy their unholy wrath upon. Inside this PDF are the traits of this new playable race, new feats, inventions, colonies, factions, deities and more!
