Pathfinder RPG (1st Edition) Starfinder RPG Pathfinder RPG (2nd Edition)


The Starfinder Roleplaying Game is about more than just meeting aliens—it’s also about playing alien characters. In Starfinder, the word “race” usually refers to an intelligent, selfaware species whose members can be considered characters rather than simple monsters. While not all races are appropriate for player characters, many of them are; any creature with a racial traits entry is a member of a potentially playable race, provided that your GM approves it.

Supposedly descended from the inhabitants of the two planets whose destruction long ago formed the Diaspora asteroid belt, sarcesians have adapted to low-gravity and thinair environments. Standing between 10 and 15 feet tall with bulbous eyes and spindly, elongated limbs, a sarcesian is able to adapt her physiology to survive in space by suspending her respiration and growing a pair of butterfly-like wings made of pure light. The wings act as solar sails, catching currents of radiation to propel her between the handful of inhabited asteroids and space platforms within the Diaspora.

Thanks to arcane engines left behind by the sarcesians’ ancestors, the race has long managed to maintain creche worlds—asteroids with enough magical atmosphere, gravity, and warmth for the inhabitants to live comfortably and raise offspring. Compared to some other planets in the Golarion system, sarcesian creche worlds are beautiful and idyllic. They contain fields, forests, hills, lakes, and bucolic towns whose populations number in the low thousands. Many of these sanctuaries are linked by the River Between, an unusual body of water that actually flows between and through the asteroids; the water is prevented from floating off into space by a tube-shaped force field crafted by unknown hands.

Sarcesians who leave the asteroid belt are sometimes hired as mercenaries specializing in surveillance and marksmanship, as they are accustomed to operating at vast distances from their targets. These sarcesians hone their innate patience even further in order to lie in wait for their marks for days atop bluffs, in dilapidated apartments, or even in the vacuum of space outside docking slips. Employers tend to pay well for this degree of dedication, making sarcesian snipers a highly sought-after commodity in certain areas of the galaxy.
