The Hive

From publisher blurb: A Race of Alien Horrors! They are known only as The Hive. Though intelligent, they rarely deign to communicate with members of other races, instead infusing them with parasitic larvae, using them as incubators until their young burst forth violently from within. First introduced in Pathfinder Roleplaying Game: Horror Adventures, this book takes the existing Hive creatures and gives them updated Starfinder stat-blocks, allowing them to take their rightful place among the stars. Additionally, it introduces two new species of Hive creature: the Hive spider, and the Hive overlord.
