Formians are a race of territorial, expansionist, ant-like eusocial monstrous humanoids native to the Colonies, a continent located in southern Castrovel.[1][2]


Formians are divided into five castes, each specialised on a nominated task. Each hive's queen is its ruler and sole egg-layer, and serving her are the myrmarchs, taskmasters, warriors, and workers. All members of a formian hive coordinate through a shared telepathic link.[3]

Formians mostly feed on fruits harvested above their hives, and sometimes supplement their diet with the flesh of predators.[4]


In ancient times, members of formian hives constantly fought against both each other and Castrovel's other native race, the lashunta. These civil wars ended with the Meeting of Queens, where the leaders of several large hives agreed to work together in service to the concept of an Overqueen, the ultimate authority figure of the formian race. The newly unified Colonies then turned their conflicts toward the lashunta,[5] who recognize the formians' Everlasting Queendoms as a perpetual threat.[6]


Formians build elaborate underground hives that can stretch up to hundreds of square miles. Formians hide the entrances to their hives and keep the ground above largely intact, so from the surface it can be difficult to recognise if one has entered formian territory.[4]

Formians fiercely defend their territory from intruders and poachers and incessantly seek to expand their presence across the universe. In order to do this, they hollow out asteroids; populate each with a single queen, a few myrmarchs and taskmasters, and hundreds of eggs; shield them with magical protection; and then launch them toward other planets. Not all such attempts succeed, but this has allowed them to spread across the galaxy.[1][4] Successful seed ships often establish colonies beneath the surface of these alien worlds,[1] and abandoned formian cities sometimes serve other races, such as the Ysoki of Akiton.[7]

On Golarion

Most people on Golarion are unaware of either the formians or lashunta of Castrovel.[8] However, formians do live beneath Golarion's surface, particularly around the Beehive in the Barrier Wall mountains of western Katapesh[1][9] and Stonespur in the Hold of Belkzen.[10]

In magic items

A storykin vision of the Harrow Deck Queen Mother.

The fabled Harrow Deck of Many Things contains a card known as the Queen Mother, which depicts a formian. Drawing this card from the deck causes formians to appear and provide aid, although they are unlikely to share a language or culture.[11]

In the Great Beyond

A colony of three sterile formian queens live in the Vault of the Onyx Citadel, within a region known as Greensend.[12][13]

The infernal duke Furcas of Forked Pyre uses the adamantine claw of an ancient formian titan named Legionnaire as the gate to the hellmouth Voulgaz.[14]
