The atmosphere of the early Cinder Epoch was a toxic cocktail of sulfuric acid and suspended iridium dust. In this corrosive environment, the Gorgon-Walkers did not merely survive; they thrived. Their skin, a complex composite of biological silica and hardened carbon, acted as a natural filtration system. As the creature known as the First Walker moved across the jagged plains of the Neo-Congo, its every step left a footprint of glass. The intense heat radiating from its underbelly fused the ash into obsidian-like craters.
Evolution in this era was not a slow crawl, but a violent sprint fueled by the lingering radiation of the Great Impact. The Gorgon-Walkers began to diverge into specialized subspecies. Some developed elongated neck-structures, allowing them to siphon gases directly from volcanic vents, while others grew massive, spade-like appendages to burrow into the cooling crust where the earth's internal heat was most concentrated.
This was the dawn of the Chemotropic Age. The biological imperative was no longer centered on the consumption of flesh—which was scarce in the wake of the extinction—but on the harvesting of raw energy. The bioluminescent sacs within their chests became more than just power sources; they became primitive sensory organs. They could "see" the electromagnetic pull of the planet's core, navigating the featureless grey world with terrifying precision.
By the end of the first century of their reign, the Gorgon-Walkers had established a hierarchy based on thermal dominance. The largest among them, the Prime Alpha, claimed the caldera of the most active volcanoes, standing like a living monument amidst the flowing lava. Its roar was not a vocalization, but a discharge of pent-up kinetic energy that could shatter stone. The Lesser Walkers, those pushed to the fringes where the air was colder and the sulfur thinner, began to develop a different kind of malice—a predatory cunning that would eventually lead to the first true hunts of the post-dinosaur world.
