Astrogation Dossier: The Shattered Worlds
The Diaspora—frequently designated by spacers as The Shattered Belt—is the sprawling asteroid field that occupies the sixth planetary orbital track of the Mataras System, adrift in the cold expanse between Verces and Eox. Comprising millions of tumbling rock masses, jagged nickel-iron asteroids, and cometary ice-bergs, the Diaspora is neither an unformed proto-planetary ring nor a natural celestial disc. It is a cosmic tombstone.
According to pre-Gap historical fragments, this orbital lane was once occupied by two lush, terrestrial sister worlds known as Damiar and Iovo (“The Twins”). Millennia ago, during an epoch of horrific interplanetary war, the neighboring rulers of Eox fired an apocalyptic necromantic planet-buster weapon. The resulting cataclysm hurled the twin planets into a direct orbital collision, shattering both worlds into billions of pulverized fragments while simultaneously rebounding to burn away Eox’s own atmosphere. Today, the Diaspora serves as a lawless frontier of mineral wealth, ancient ruins, void-adapted hunters, and cutthroat pirate armadas.
Major Celestial Bodies & Habitats
While the vast majority of the Diaspora consists of silent, airless rocks tumbling through the vacuum, several major planetoids and miraculous anomalies sustain thriving populations:

+-----------------------------------------------------------------------------+
1. Broken Rock (The Pirate Haven)
The unofficial capital of the Diaspora is Broken Rock, a colossal, hollowed-out asteroid measuring roughly thirty miles across.
- The Hollow Citadel: Long ago gutted by automated corporate mining dredges and subsequently abandoned, Broken Rock was seized by the Free Captains. Inside its cavernous interior, the pirates have constructed a chaotic, zero-gravity metropolis clinging to the curved inner hull, illuminated by neon docking beacons and powered by geothermal tap-reactors.
- The Pirate Council & The Code: Broken Rock is governed by the Pirate Council—an assembly of the most ruthless corsair commodores led by an elected or self-appointed Pirate King. Here, the loose tenets of the Code of Asteroids are enforced: disputes are settled in dueling cages, stolen cargo is laundered through black-market fences, and imperial law enforcement like The Stewards is shot on sight.
2. The River Between
One of the most breathtaking magical and gravitational enigmas in the galaxy.
- A Torrent in the Void: The River Between is a continuous, self-contained ribbon of breathable oxygen and pure freshwater that snakes freely through open space, connecting dozens of micro-asteroids across thousands of miles.
- Metaphysical Anchor: Ancient environmental stabilization fields and primordial elemental water runes (dating back to lost Damiar) keep the current from vaporizing in the hard vacuum or freezing solid. Sarcesian pilgrims and eccentric spacers navigate the river in canoes, glass-bottomed launches, and paddle-skiffs, harvesting rare aquatic plants and freshwater delicacies found nowhere else in the system.
3. Nisis (The Ocean Beneath the Ice)
Located along the colder, outer rim of the belt toward Eox, Nisis is a dwarf planet composed almost entirely of slush, methane ice, and frozen ammonia.
- The Abyssal Sub-Ocean: Beneath an exterior ice crust miles thick lies a dark, high-pressure liquid ocean warmed by tidal friction and deep thermal vents.
- Apex Cryptids & Outposts: Corporate research stations drill deep shafts into Nisis’s ice to harvest rare cryogenic chemicals. Deep within the sunless seas dwell the Kalyama—monstrous, bioluminescent apex predators possessing unsettling telepathic hunting lures—who relentlessly hunt mining divers and submarine probes.
4. Dwarven Star Citadels
Carrying on their ancient cultural heritage of stonecraft and metallurgy, clans of Dwarves have colonized the densest metallic asteroids in the belt.
- Adamantine Forges: Deep inside hollowed-out iron asteroids like Torag’s Anvil, Hearthstone, and the mighty corporate stronghold of Star Citadel Theodrane, dwarven mining conglomerates like Ulrikka Clanholdings operate colossal solar smelters. They refine adamantine, cold iron, and titanium directly from belt ore, fabricating reinforced hull plating and starship keels for commercial shipyards, mercenary fleets, and defensive orbital bastions.
5. The Wrecking Grounds
Gravitational eddies and erratic micro-singularities throughout the Diaspora create natural debris traps. The Wrecking Grounds is a vast expanse littered with thousands of derelict starships spanning millennia: pre-Gap colony vessels, ancient Eoxian death-cruisers, lost exploration frigates, and ships sheared in half by miscalculated Drift jumps. It is a lethal treasure trove for salvagers, crawling with rogue security constructs, vacuum-born scavengers, and the unquiet spirits of long-dead crews.
Native Peoples: The Sarcesians
The only native biological survivors of the twin worlds of Damiar and Iovo are the Sarcesians—a remarkable and enigmatic species uniquely adapted to life in the void.
Biology & The Solar Wings
- Anatomy: Sarcesians stand between 10 and 15 feet tall, with elongated, spindly limbs, pale hairless skin, and multi-faceted, nocturnal eyes. Their bodies contain specialized metabolic organs that produce internal oxygen reserves and withstand vacuum decompression.
- Wings of Pure Light: When stepping out into hard vacuum, a Sarcesian can mentally trigger specialized luminescent organs along their spine, unfurling magnificent wings composed of coherent photons and magnetic force. These wings absorb solar radiation for sustenance and catch the solar winds, allowing Sarcesians to glide silently between asteroids without spacesuits, thruster packs, or starships.
Culture & Marksmanship
- Crag Communes: Sarcesians live in close-knit family clans stationed on isolated asteroids known as crags. They cultivate delicate moss-terraces beneath localized force bubbles, relying on cometary water mining to maintain self-sufficiency.
- The Long Rifles: To defend their small ice-caches and isolated family crags against ravenous space pirates and corporate claim-jumpers, Sarcesians developed an extraordinary martial tradition of sniper warfare. Utilizing custom-crafted, oversized projectile rifles firing dense tungsten-alloy rounds, a trained Sarcesian sniper can calculate gravitational drift and eliminate targets across planetary distances—often striking trespassers from tens of miles away across open vacuum.
The Free Captains & The Outlaw Economy
While the Pact Worlds boast of civil law and constitutional liberty, the Diaspora is the untamed frontier where might makes right.
Piracy & Smuggling
The Free Captains prey upon the lucrative trade lanes connecting the inner planets (Castrovel, Verces, Absalom Station) to the outer rim. Operating sleek, heavily weaponized corvettes disguised as bulk haulers or hidden in asteroid sensor shadows, they board commercial convoys to seize valuable electronics, weapons, and pure water-ice.
The Code of Asteroids
The Free Captains are not mindless slaughterers; they are bound by a complex, brutal pirate charter. Under the Code:
- A captain who surrenders without firing may negotiate ransoms for their crew rather than being spaced.
- Stealing from another captain within the boundaries of Broken Rock is punished by exile or keelhauling through an asteroid’s drive exhaust.
- In times of existential threat—such as the historic invasions of the Veskarium or the Swarm—the Pirate Council honors temporary alliances with The Stewards, transforming their marauders into a lethal, asymmetric guerrilla defense fleet.
Politics & The Pact Council
Technically, the Diaspora is recognized as a sovereign territory within the Pact Worlds, holding an official delegation seat on the Pact Council on Absalom Station.
In practice, this seat is a source of bitter, comical discord. The Diaspora’s delegate is rarely a unified representative; instead, the seat alternates between an aloof Sarcesian elder who cares nothing for station politics, a corporate dwarven mining lobbyist, and an audacious, formally pardoned Free Captain admiral who uses diplomatic immunity to coordinate smuggling rings directly beneath the Stewards’ noses.
Campaign & Adventure Hooks
- The Fifty-Mile Shot: A corrupt executive from AbadarCorp is shot dead through the armored observation window of a luxury cruiser transiting the belt. Ballistic telemetry reveals the kinetic slug was fired from an unmapped asteroid 45 miles away. The PCs are hired to track down the legendary Sarcesian sniper responsible—only to discover the executive had poisoned the sniper’s ancestral crag to illegally seize its water rights.
- Heist on Broken Rock: A notorious Free Captain commodore has captured a datapad containing encrypted coordinates to a pre-Gap military bunker hidden within a tumbling metallic asteroid. The party must venture into the lawless heart of Broken Rock, navigate the pirate dens, and extract the datapad before the commodore sells it to the Corpse Fleet.
- Drift in the River Between: A strange ripple in the current of The River Between reveals an ancient, submerged temple dating back to pre-shattering Damiar. As the party explores its flooded, zero-gravity chambers, rival dwarven salvagers and water elementals converge to seize the site’s primordial terraforming engine.
