A species of insect-like expansionists found across the galaxy, formians are fiercely territorial and militaristic in their efforts to spread their race to the farthest reaches of space. Having long ago outgrown their distant homeworld, the formians hollow out asteroids to create massive hives, then launch these seed ships into the darkness, bound for far-off worlds.
Formians can be found below the surface of many worlds, including Golarion, where they are known to reside in the mountains of western Katapesh. Their most prominent hives in this solar system, however, are on Castrovel, in a vast continental region known by many names but commonly referred to as “the Colonies.” While they currently have a formal peace between them and the more populous lashunta, the long history of violence between the races makes this truce uneasy at best.
Rules: The complete rules for various formian creatures appear in Pathfinder RPG Bestiary 4. Players who have their GM’s permission could easily adopt the rules for formian workers (Bestiary 4 113) to create a playable character race (substituting class Hit Dice for the worker’s racial Hit Dice), using the same types of considerations as those given to centaur characters (Pathfinder RPG Advanced Race Guide 218) with regard to their six legs.
