For over two thousand years, mapmakers, philosophers, and empires believed in a vast, southern landmass—Terra Australis Incognita, the “Unknown Southern Land.” It appeared on countless maps, inspired legendary voyages, and was thought to be Earth's perfect balance to the known continents of the North. But when explorers like James Cook searched for it, they found nothing but ice. Was Terra Australis simply a mistake… or a memory of a lost land? Could it have been an ancient civilization buried beneath Antarctica’s ice? And if so, who erased it? Join host Silas Gray on Cold Logic as we investigate the rise and erasure of the most persistent phantom continent in human history—and ask whether Terra Australis ever truly vanished, or if it's still hidden beneath centuries of secrecy.

For centuries, maps included a large island near Greenland called Frisland—then it vanished. Was it a mistake, a myth, or a deliberate erasure? Join host Silas Gray as he journeys to the frigid North Atlantic to explore the Zeno Map, the cartographic consensus of the 16th century, and the geopolitical motives behind the disappearance of a continent-sized landmass. In this cinematic Cold Logic investigation, we challenge the official narrative and ask what secrets were so powerful they had to be erased from the map.
