Travelling through hyperspace can sometimes lead to strange and terrifying results. Each time a ship uses its hyperspace engine, the crew may soon find themselves either flying through empty hyperspace to their intended destination or passing by a random chunk of another plane. Few people would be pleased to find themselves in either Hell or the Abyss, and even fewer would want to be steering through a hybrid of these two fiendscapes! Close Encounters: Hyperspace Fiends introduces brand new rules for interacting with this treacherous subsection of hyperspace and provides stats for 13 of these demons and devils, from the lowly dretch, to the vicious bone devil, to the sword-and-rifle wielding marilith. Also included are two new ships straight from the Lower Planes: the Hellish Soulreavers and the Abyssal Dreadrazors. Close Encounters is a line of Starfinder Roleplaying Game compatible books from Fat Goblin Games filled with a ready-made encounter and numerous plot hooks and adventure seeds for Gamemasters to quickly adapt for their own tables. Each book includes fully statted monsters and NPCs for the Starfinder Roleplaying Game, sometimes all new, sometimes adapted from other game systems, sometimes both.
