The infamous Delverworld of Ghosar Quintus

A Delverworld is a planetoid settled by the Imperium that is given over completely to mining operations. Most Delverworlds can also be more formally classified by the Adeptus Terra as Mining Worlds. Delverworlds are particularly common in the Eastern Fringe of the galaxy.

Notable Delver Worlds

  • Ghosar Quintus - Ghosar Quintus was among the most well-known Delverworlds in Segmentum Ultima and was ruled by the nobles of the Trysst Dynasty. Before the hideous truth of Ghosar Quintus was revealed by a Deathwatch Kill-team under the command of the Ultramarines Chaplain Ortan Cassius, it was used as a prime exemplar of a "Delverworld," a planetoid given over entirely to mining the Eastern Fringe. Its tithes were consistently at least a fifth higher than the required level, and the adamantium mined from its substrata was purer than any other source in the sector -- every ingot polished to a bright sheen, neatly stacked and dutifully categorised by countless Trysst workers. More than that, the dynasty's workers were content to subsist only on gruels and nutrient pills, and there were no recorded incidences of unrest. To the Imperium they seemed a model population. When this came to light through the planet's tithe reports and later Lexmechanic assessment, the Departmento Munitorum shipped out work groups of the Trysst Dynasty to every other Delverworld within reach, there to act as consultants and role models for the other, less efficient populations to aspire to. But in truth, Ghosar Quintus was home to a Genestealer Cult, the Cult of the Four-Armed Emperor, which used its model reputation and the efficiency of its workforce to spread its version of the Genestealer Cult across half the galaxy.
