The First Expedition: Whispers in the Dark
The relentless growth of Nadaren required an ever-increasing flow of raw material. As the old-growth timber of the southern forests dwindled into stump-fields and the surface mines yielded progressively lower grades of iron and coal, Nadaren's High Industrial Council turned its gaze downward. The empire's cartographers and geological scouts were dispatched to the northern frontier, tasked with mapping deep fissures, forgotten sinkholes, and subterranean fractures that might lead to untouched veins of ore.
It was during a survey near the base of the northern mountains that an engineering company, utilizing high-yield explosive charges to clear a collapsed ravine, inadvertently unsealed a structural void. Beyond the blasted granite lay a vast, natural descending shaft that plunged straight into the subterranean depths—a gateway leading directly toward the Obsidian Underreach.
Recognizing the potential significance of the discovery, the regional garrison commander assembled the First Expedition. Consisting of forty hand-picked men—a mix of veteran scouts, coal-mining engineers, and practical geologists—the team descended into the shaft equipped with heavy leather coats, carbide lanterns, climbing tackle, and early-model repeating rifles.
As they descended deeper, the rough granite gave way to jagged walls of jet-black volcanic glass and razor-sharp basalt formations. The air grew thick with the sulfurous tang of deep thermal vents, and the daylight above faded into absolute darkness.
For twelve days, the expedition mapped the upper margins of the Underreach. Their reports, later submitted to the Council chambers in Nadaren, were filled with awe and unbridled industrial avarice:
Incalculable Mineral Wealth: The surveyors documented massive subterranean cliffs laced with rich seams of high-purity iron, rare crystalline ores, and raw mana veins pulsing through the living rock. The geologists noted that a single cavern system contained enough high-grade coal and heavy metals to fuel Nadaren's blast furnaces for a century.
The Obsidian Standard: The survey team noted strange, discarded fragments of high-precision gearwork along the perimeter of several subterranean lakes—micro-engineered cogwheels made of polished obsidian and ruby bearings that operated without steam, fuel, or sound.
The Uncanny Impression: Despite the staggering financial prospects, every journal recovered from the expedition contained notes of deep psychological strain. The scouts reported a persistent, skin-crawling sensation of being monitored from the darkness. Every shadow beyond the edge of their lantern light felt heavy and deliberate; every echo of falling water seemed to carry a faint, rhythmic clicking or low, mocking whisper. Yet, no matter how many flares were fired or how carefully the perimeter was searched, the scouts found nothing.
What the Nadaren explorers did not realize was that their intrusion had been noticed within minutes of the initial breach. To the Dokkalfar, who had spent centuries surviving in an environment of absolute scarcity and constant subterranean threats, forty noisy surfacers clattering through the dark with roaring oil lamps and clanking gear were no threat at all.
The Great Houses of the Underreach watched the First Expedition with dark amusement. The Dokkalfar shadow-weavers and scouts simply tracked the team from the upper basalt ledges, evaluating their gear, assessing their physical capabilities, and mocking their complete inability to navigate without daylight. Viewing the surfacers as clumsy, harmless curiosities, the Dokkalfar allowed the expedition to complete its survey and ascend back to the surface completely unharmed.
