Below S01 (2026)

🌊 Stationed aboard the Tethys-9, an experimental deep-sea atmospheric research facility anchored four miles below the surface in the Puerto Rico Trench, a specialized team of marine scientists and deep-submergence engineers conducts classified oceanic crust sampling. ⚡ When a catastrophic subterranean seismic event abruptly shears their primary umbilical tether to the surface support vessel, the facility is plunged into total darkness and isolation. 🚨 With life support oxygen supplies steadily depleting and structural bulkhead integrity failing under crushing hydrostatic pressure, the surviving crew scrambles to engineer an ascent. 👁️ However, as psychological paranoia fractures the group, they soon realize the tremor was not geological: an ancient, apex subterranean organism has awakened from the abyssal rift, hunting their claustrophobic metal habitat from the shadows. 💥
