Overview: The Engineers of the Void
Small in stature but colossal in personality, the Ysoki—often affectionately or derisively termed “ratfolk”—are among the most adaptable, industrious, and widespread species in the Pact Worlds. While other civilizations claim grandeur through towering ivory spires or mighty battlefleets, the Ysoki have conquered the galaxy from the inside out: through maintenance ducts, conduit crawlspaces, scrapyard stalls, and the engine rooms of nearly every starship plying the void.
Born from the harsh, resource-depleted rust plains and subterranean warrens of Akiton, the Ysoki evolved a cultural ethos centered on relentless scavenging, fierce familial solidarity, and an almost instinctual affinity for machinery. Whether a beat-up tramp freighter in The Armada or a premier laboratory in The Arcanamirium, if machinery hums, an Ysoki is likely nearby with a hydro-spanner in hand, a spare plasma-fuse tucked safely inside a cheek pouch, and an uninterrupted stream of rapid-fire commentary.

Biology & Distinctive Adaptations
1. Compact Frame & Sensory Agility
Standing roughly three to four feet tall, Ysoki possess lightweight skeletons and flexible musculature allowing them to squeeze through conduits and maintenance hatches designed for maintenance drones. Their large, multifaceted ears provide acute auditory awareness, while their sensitive facial whiskers detect micro-vibrations and changes in atmospheric pressure—an invaluable trait when navigating depressurizing starship corridors.
2. The Famous Cheek Pouches
The defining anatomical signature of the Ysoki is their pair of stretchable, subdermal cheek pouches. Extending along the sides of the jaw down toward the collarbone, these pouches can expand to hold an astonishing volume of matter (up to one cubic foot). An Ysoki can comfortably conceal a small blaster pistol, a complete electronic slicing kit, emergency rations, or a handful of credsticks inside their cheeks without hindering speech, though their face visibly swells into a charmingly comical bulge.
3. High Metabolism & Moxie
Ysoki possess extraordinarily quick reflexes and a natural resistance to environmental hazards, toxins, and electrical shocks—adaptations forged in the toxic minefields and radiation leaks of Akiton. Their rapid nervous systems give them an edge in high-speed firefights and sudden depressurization emergencies, inspiring the common void-dock saying: “When an airlock blows, follow the rat.”
Culture, Psychology, and Clan Loyalty
To understand an Ysoki, one must understand the Warren. Ysoki are profoundly social creatures who thrive in close, crowded physical contact. While other species suffer claustrophobia in the tight crew bunks of mining vessels or the crowded tenements of The Spike, Ysoki find comfort in warmth, ambient chatter, and proximity to their kin.
The Sacred Clan
Family is absolute. An Ysoki will relentlessly barter, haggle, and cheat a stranger out of every credit in a deal on The Freemarket, only to turn around and give every credit to a cousin needing a starship drive overhaul. Insulting an Ysoki is easily laughed off, but insulting an Ysoki’s clan or family is the swiftest route to a vicious, coordinated brawl.
The Tinker’s Compulsion
Ysoki cannot leave inert technology alone. They have an innate, almost irresistible urge to take machinery apart, examine its internal logic, modify it with extraneous blinking LEDs, and rebuild it into something faster, louder, or more dangerous. While corporate engineers at AbadarCorp often view Ysoki modifications as chaotic fire hazards, Ysoki creations often outperform factory specs under extreme conditions.
Ysoki on Absalom Station
Ysoki represent one of the largest demographic populations aboard Absalom Station, forming the vital mechanical workforce that keeps the station’s life-support and grav-plating operational:
- Little Akiton: The cultural capital of station Ysoki. The air here smells of pungent red spices, sulfur, and ozone. Cramped, stacked shanties connect via suspended gangways, while street markets hum with haggling and tinker shops.
- The Spike & Downlow: Ysoki crews dominate the lower-deck salvage operations, crawling into the forgotten, zero-G conduits of The Ghost Levels to reclaim scrap metal and lost pre-Gap circuitry.
- The Master of Stars: The spiritual home of spaceborne Ysoki. Faction leader Fitch has turned the mid-decks of the colossal Starfinder flagship into a sprawling communal nest where young ratfolk learn astrogation, soldering, and piloting.
GM Plot Hooks & Operational Scenarios
- The Pouch Contraband: An Ysoki courier accidentally swallows a microscopic data-chip during a customs shakedown in The Arms. The encrypted chip contains corporate blackmail stolen from an Aspis director, and mercenary hit-squads are now tearing apart Little Akiton to capture the courier alive.
- The Ducts of the Ghost Levels: A vital atmospheric scrubber fails in The Spike, and only a slender team of agile mechanics can squeeze through the contaminated, radioactive service conduits to replace the valve. The PCs must escort an eccentric Ysoki grease-monkey past rogue repair drones and lurking mutants.
- Clan Feud in the Freemarket: Two rival Ysoki merchant clans spark a chaotic gang war across the stalls of The Freemarket over an ancient piece of pre-Gap scavenged hardware that both claim belonged to their shared great-grandmother. The PCs are hired to mediate before station Stewards deploy riot squads.
