Overview

A planet smothered by its own sky, Neravar Prime hides in plain sight. Its atmosphere is breathable—barely. Its gravity is forgiving. But the true cloaking shroud lies in its endless swarms of gasborne xenoforms, obscuring the planet from Imperial auspex and pict-scan arrays.

Founded by the infamous Reaver King Horrold the Three Fingers, Neravar Prime is a lawless colony of fugitives, renegades, and black market technologists, thriving in the blindness of Imperial auspex

Haven Drift: The Pirate Colony

The colony sprawls across the rare high ridges of Neravar Prime, built from:

Grounded starship hulls, cannibalized and reforged into hab-blocks, workshops, and fortresses.
Container-stacks, forming labyrinthine markets and slums.
Jury-rigged plasma foundries and servo-forges, belching toxic plumes into the methane-laden sky.

Fugitives from Imperial justice—voidborn, deserters, outlaw tech-adepts—are drawn to Haven Drift, swelling its ranks and providing crews for visiting ships.

The economy is harsh and brutal:

Hereteks ply their trade openly, offering forbidden augmentations, xeno-tech adaptations, and experimental cybernetic grafts, beyond the reach of Mechanicus orthodoxy.

Slavery is common, especially in the forges and docking bays.

Skilled mechanics and cyber-augurs fetch exorbitant prices, often “recruited” through press-gang seizures.

Trade, Vice, and Heretek

Haven Drift’s markets are a maelstrom of illicit commerce:

Aerolith-derived gases are refined into crude fuels and black-market promethium.
Xeno-organic materials from the planet’s predators are crafted into combat drugs.
Captured STC tech, scavenged or stolen, is reworked into experimentaldesigns.
Heretek enclaves openly offer grafting of xenos components, unstable pattern weapons, and “shadow augmetics” that defy Imperial design protocols.

Every transaction is laced with betrayal, every alliance temporary. Survival here is bought with guns, credits, and fame.

Vessels of the Drift: The Aerolith Anchorage

High above the colony, amidst the Aerolith swarms, pirate vessels maintain station-keeping at high altitude, using:

Gravitic anchor, tethering ships to low altitude moorings while suspended within the cover of gaseous lifeforms,.

The Aeroliths’ bio-electric fields further mask the ships, making Haven Drift invisible to standard Imperial long-range scans.

The Mausoleum of Horrold the Three Fingers

At the heart of Haven Drift, amidst its labyrinth of scavenged starship hulks and rusted gantries, rises the Mausoleum of Horrold the Three Fingers—a brooding monument of black iron and xeno-forged stone, constructed by Horrold’s own order at the founding of the pirate colony.

No one knows what rests within.

Though Horrold met his end in a distant void battle, his body lost to space, the mausoleum was always meant to be more than a grave. Whether it holds treasures, forbidden knowledge, or nothing at all, only Horrold knew the truth. Its presence alone was enough: a statement of dominion, a monument to his legacy.

The entrance remains sealed by twin gene-lock obelisks, encoded solely to Horrold’s genetic signature. No heir, no key, no override exists. All attempts to bypass them have failed with lethal consequence.

Guarding the mausoleum is the dreaded Spectral Guardian—an ancient defense-construct bound to the tomb’s sanctity. Appearing as a blazing wraith of photonic energy, the guardian immolates intruders in bursts of collapsing light, vaporizing flesh, armor, and even hardened augmetics within moments.

In Haven Drift’s bloody history, many have tried to breach the tomb:

Hereteks seeking xeno-artefacts,
Rival warlords hungry for Horrold’s hidden spoils,
Thrill-seekers chasing legend.

All have been reduced to ash before the mausoleum’s cold gate.

Over time, approaching the tomb has become a ritual of bravado among pirate captains. To stand before its gene-locked threshold is to acknowledge Horrold’s enduring rule, even in death.

Yet none dare breach it now. Not out of reverence—but survival.

The mausoleum remains, as it always has:
a sealed vault, a killer of the curious, a monument to a king who would not be forgotten.The Mausoleum of Horrold the Three Fingers

The Surface: Predators On the Moss

While the gasborne Aeroliths fill the sky with endless interference, the planet’s surface presents its own lethal deception.

The moss carpets that blanket Nerakhar Prime are, in most cases, harmless sponge-like flora, stabilizing the thin soil layers.
However, scattered across the plains and valleys are xeno-predators known as “Falsemosses”—vast, ambush predators that mimic the appearance of the passive moss but are entirely carnivorous.
These organisms, technically classified as Ambulentia macro-lamiae, remain dormant for months, until they detect movement, body heat, or bioelectric activity.
When prey is sensed, they contract with alarming speed, engulfing the victim in chitinous lobes lined with paralytic spines. The immobilized prey is then slowly dissolved over days.
