Hidden within the Nordic Union, this mining complex is one of only twelve of its kind worldwide, built to push the limits of mineral exploration and extraction. Its structure is divided into two halves, each serving a distinct role.
The upper half rises as a vast dome, a closed ecosystem sustaining life and research. Spread across three tiers, it houses worker quarters, communal amenities, and laboratories dedicated to mineral analysis and experimentation. Within this dome, the community functions like a small, self-contained city.
Beneath it lies the lower half: a massive drill designed for perpetual motion. Three concentric levels encircle the facility's heart — the Engine — where processing plants and laboratories refine the minerals drawn from below.
The Engine itself is the largest machine humanity has ever built, occupying more than eighty percent of the lower structure's volume. Designed to run for centuries without pause, it generates the energy required to keep the drill in constant rotation. This ceaseless motion produces centrifugal force, creating a gradient of gravity between the dome above and the drill below — a condition unique to facilities of this design.
Both halves are encased in a thirty-meter-thick protective shell, shielding the installation and its inhabitants from the stresses of deep-earth excavation. Together, the Dome and the Drill stand as a testament to human engineering, resilient against the most punishing environments beneath the earth.
