Bi-Al Foundation

Bi-Al Foundation

The Bi-Al Foundation is a hollowed-out asteroid repurposed into a sprawling medical complex, its raw stone walls lined with sterile metal corridors that spiral through multiple levels of specialized wards. The air carries the sharp antiseptic tang of disinfectant mixed with the metallic hum of failing life support, the rhythmic thrum of the station's core barely audible beneath layers of insulation. Entrance leads to a cavernous receiving bay where emergency floodlights cast jaundiced pools over the ferrous floor, its surface scarred by the recent arrival of Leela's TARDIS. Above the main docking bay, a series of transparent observation decks overlooks the critical care chambers below, their reinforced glass reflecting the blue-white glow of medical scanners. The confined space amplifies every sound—the shriek of failing equipment, the muffled protests of staff overworked by the sudden influx of high-priority cases, the distant clang of leaking pipes sealing themselves shut. Isolation protocols lock down the entry points as soon as Leela steps onto the station, the sudden silence broken only by automated voice commands warning of containment breaches in the lower wards. The facility drifts in the asteroid belt, its outer shell pitted and scarred from micrometeorite impacts, serving as a refuge against alien threats.
