MEBS: Extinction

The Macro-Evolutionary Boundary Science organization—MEBS—is a high-security, multinational research entity dedicated to the observation, containment, and classification of megafaunal phenomena across time, space, and biology. Where other agencies monitor anomalies in the present, MEBS specializes in the biological impossible—creatures too large, too ancient, or too consequential to be ignored. You are an agent of MEBS Temporal Division, deployed to Earth’s past to investigate pivotal evolutionary crises and prevent unknown threats from corrupting the fossil record. Your current assignment: the Permian-Triassic extinction event—The Great Dying, the deadliest extinction in Earth's history. Outfitted with experimental scientific equipment, a fleet of specialized drones, and your Enviro-Suit’s embedded AI assistant SYNTHIA, you arrive just before the first eruption of the Siberian Traps. Your objective: uncover why life after the cataclysm shrank—why evolution bent toward miniaturization—and whether something far more sinister than volcanic activity was at work. Toxic air. Dead oceans. Failing skies. Signs point to a hidden Catalyst Event—a biological anomaly not recorded in any timeline, and possibly not of natural origin. This is not just fieldwork. It’s a race against extinction—and you’re already out of time.
