Gosreg

Gosregs are agents of the Dominion of the Black who insinuate themselves into humanoid societies to implement the goals of their sinister masters. They're generally tasked with observing and waiting, hiding in disguised forms until their location is ripe for harvest. When this occurs, they reveal themselves as living psychic beacons, signaling their distant masters and guiding invasion forces. Over the years of an infiltration, a gosreg will assume dozens of roles, relishing any intense emotions it can inspire while laying the groundwork for future identities.

In their natural form, gosregs dart about in a jerky gallop due to stumpy legs, gangly arms, and oversized heads. They take on the appearances of humanoids to infiltrate societies, and they drop these disguises only when they're compromised and must resort to physical violence to continue their mission.

The Dominion of the Black is a conglomeration of deep-space conquerors with a strong presence on Aucturn, the most remote planet in Golarion's solar system. The Dominion has secret outposts all over Golarion; most of its members on the planet are scouts, using their skills to steal brains and identities, gathering information without any consideration for the inhabitants of the worlds they infiltrate.
