Raw ore is crushed, sorted magnetically to remove impurities, then smelted in specialized furnaces lined with non-reactive ceramic. The process occurs in four distinct phases, each presenting unique challenges.
Initial heating to 847 degrees Celsius causes the ore to begin humming—faintly at first, then with increasing intensity as temperature rises. Workers must wear hearing protection, though the sound is transmitted as much through bone as through air. Some report that the humming forms words at this stage, though no two workers agree on what the words might be.
The liquid phase, occurring between 1,200 and 1,600 degrees Celsius, produces the most dramatic phenomenon. Molten runite displays surface patterns resembling written language—complex characters that form, dissolve, and reform continuously. Linguists have attempted to translate these patterns without success, though several have been committed to care facilities after claiming the characters were speaking directly to them.
Pouring presents practical difficulties, as liquid runite resists leaving the crucible. Experienced smelters describe the process as "persuasion" rather than pouring, requiring steady psionic "encouragement" to convince the material to flow into molds. Inexperienced smelters sometimes find that the runite refuses entirely, remaining in the crucible until it cools—and then responding to the rejection with audible disappointment.
Cooling must occur at precisely one degree Celsius per minute. Faster rates cause quantum fractures that render the material useless for high-grade applications. Slower rates allow the runite to develop opinions about its shape—finished bars have been known to slowly reconfigure themselves into forms their coolers found aesthetically pleasing.
Yield varies significantly by grade. One ton of raw ore produces approximately two hundred kilograms of standard industrial-grade runite bars. Memory-pure grade, required for prophecy lances and judgment blades, requires additional processing and yields only fifty kilograms. Chorus-grade material, produced exclusively by the Melded Kin, achieves purity levels approaching one hundred percent through methods that Imperial scientists have been unable to observe without experiencing conversion themselves.
The Imperial Geological Survey maintains several competing theories regarding runite's anomalous properties.
The accepted theory describes a quantum memory lattice—runite's crystalline structure existing in a state of quantum coherence that allows it to "remember" every energy state it experiences. Every electron that passes through leaves an imprint at the quantum level, faint but permanent. This explains both self-repair (the lattice reverts to its remembered optimal structure) and psionic response (thought is energy, and energy leaves traces). However, this theory fails to explain why runite remembers pain specifically, or why it sometimes answers back when questioned.
A speculative theory proposes extradimensional resonance—that runite is not native to our dimension. The singing may be resonance from elsewhere, a place where thought and matter are not separate. This would explain the written characters that appear during smelting; they're not random slag patterns but language from somewhere else. It would explain psionic amplification as a bridging effect between dimensions. And it would explain conversion—miners who don't just hear the song but follow it, somewhere the rest of us cannot see.
Supporting evidence includes deep-vein runite occasionally containing inclusions that cannot be analyzed by any known method. These inclusions appear as faces—frozen, screaming, and according to some researchers, curious. Attempts to extract these inclusions have universally failed; they retreat deeper into the material or simply vanish when approached.
A heretical theory, suppressed by Imperial authorities but persistent among mining communities, proposes that runite is not a mineral but an organism. Veins are its nervous system. Mines are wounds. Refining is dissection. Evidence cited includes runite's self-repair capability, the pulsing rhythms detected in undisturbed veins, miners who stay too long continuing to mine even after death, and the singing—which proponents insist is not random but communication. The official response to this theory is silence. The unofficial response is that those who promote it tend to... keep mining, eventually.
Industrial-grade runite forms the backbone of Imperial infrastructure. Structural supports in major cities incorporate runite for its self-repair properties. Ship hulls use runite plating that automatically seals breaches. Bulk transport containers leverage runite's perfect conductivity for efficient energy transfer.
Arms-grade runite represents the most common military application. Weapons forged from this material respond to their wielders' intentions, reducing reaction time and increasing accuracy. Armor incorporates runite for its ability to distribute impact energy and self-repair battlefield damage. Tactical equipment uses runite components for their reliability under extreme conditions. The primary drawback is that such equipment remembers combat—used blades carry echoes of every strike, and veteran soldiers report that their armor develops opinions about tactical situations.
Memory-pure grade is restricted to specialized applications requiring full quantum retention. Prophecy lances of the Eternal Vigil incorporate memory-pure runite to capture and preserve visions. Judgment blades of the Adamant Crown use the same grade to ensure that no soul's record is lost. Vigil equipment generally requires memory-pure components for maximum sensitivity, though handlers must undergo extensive training to avoid cognitive bleed.
Chorus-grade material is produced exclusively by the Melded Kin through organic refinement processes. The resulting runite achieves unprecedented purity and responsiveness, but at a cost: it remains alive in ways that Imperial science cannot fully explain. Chorus-grade weapons sing constantly. Chorus-grade armor breathes. Chorus-grade users report feeling accompanied at all times. The Imperial position is that such material should not exist. The Melded Kin position is that it should not exist separately.
Cognitive bleed represents the most common hazard associated with runite exposure. Personnel handling runite for extended periods report receiving memories and thoughts from previous users. In mild cases, this manifests as déjà vu or unexplained familiarity with unfamiliar situations. In severe cases, affected personnel lose the ability to distinguish their own memories from those embedded in the material. Standard prevention involves limiting exposure duration and requiring memory-pure grade handlers to work in pairs for mutual verification.
Psionic feedback occurs when runite "answers" unauthorized mental contact. Users who think about inappropriate subjects while in contact with runite may receive responses—images, emotions, or instructions—that originate from the material itself rather than any identifiable source. Training emphasizes mental discipline, though experienced handlers note that runite seems to prefer certain thought patterns and rewards users who think in ways it finds pleasing.
The Song represents the most insidious hazard. Prolonged exposure to runite causes auditory hallucinations—first faint, then persistent, finally overwhelming. Those affected report hearing music, voices, or simply a sustained note that seems to come from everywhere at once. Continued exposure leads to conversion, a state in which affected individuals voluntarily approach the nearest vein and... merge. Prevention requires rotating personnel every six hours and absolutely prohibiting sleep within runite storage areas. Treatment for early-stage Song exposure consists of isolation from all runite for a minimum of thirty days. Treatment for late-stage exposure does not exist.
Memory imprint occurs when runite remembers a user strongly enough that subsequent handlers experience that user's identity. A blade used by a single soldier for years will eventually contain enough of that soldier's quantum signature to overwrite new users temporarily. Handlers of such weapons report periods of missing time during which they remember doing things "as someone else." Prevention involves rotating weapon assignments and never allowing single users exclusive access for extended periods. Treatment consists of reassignment to duties without runite contact.
Inclusion emergence represents the rarest and most disturbing hazard. Refined runite bars occasionally develop visible inclusions that were not present during initial inspection. These inclusions take the form of faces—distinctly drow features, frozen in expressions ranging from terror to ecstasy. Attempts to analyze the inclusions reveal nothing; they are simultaneously present and absent, solid and immaterial. Official protocol requires immediate reporting and isolation of affected bars. Unofficial protocol prohibits recognizing any faces that appear.
