The Naphtha Cluster

Fire and Fever

"Ignis lights the world; Alvearium makes it bearable."

Stretching across the toxic, shimmering tides of the Mare Aeterna Incendia, the Naphtha Cluster is a landscape of blackened iron and neon-streaked fog. Here, the air doesn't just carry the scent of industry—it carries the weight of it. To the north stands Hive Ignis, a roaring pillar of flame and pressure. To the south lies Hive Alvearium, a sprawling complex of pressurized domes and sterile, flickering laboratories.

They are bound together by the "Great Arteries"—a massive, miles-long network of fortified pipelines and armored mag-lev tracks that ferry the toxic lifeblood of the region between the two giants.

The Two Pillars

• Hive Ignis (The Furnace): The brutal heart of the cluster. Ignis is a vertical refinery dedicated to the violent "cracking" of raw precursor. It is a place of extreme heat, colossal pressure, and the constant roar of flare stacks. It produces the high-grade promethium that powers Necromunda’s war machines, exporting the raw power the Imperium demands.

• Hive Alvearium (The Apothecary): While Ignis burns, Alvearium distills. Using the volatile chemical byproducts pumped in from Ignis, Alvearium’s vast manufactorums specialize in the delicate and the deadly. It is the sector's primary source for industrial solvents, medicinal stimms, and the high-grade combat drugs that keep the Hive’s workers—and its gangs—functioning.

The Shadow Trade

In the Naphtha Cluster, the law is written in chemical formulas. The Palanite Enforcers guard the primary pipelines with lethal force, but in the "Dead Zones" between the Hives, the flow is compromised.

Gangs battle for control of Siphon-Stations and Valve-Hubs, tapping into the Arteries to steal raw fuel or precious chemical precursors. Whether you are fighting for the raw heat of Ignis or the liquid gold of Alvearium’s drug-vats, one truth remains:

In the Naphtha Cluster, you are either part of the process, or you are the waste.
