Just under 1500 years ago something terrifying happened to the world’s climate something nobody could understand the sun began to go dark and rain the color of blood poured from the skies. Clouds of fine dust enveloped the Earth and winter gripped the land for two whole years. Then came drought, famine, plague, and death. Whole cities were wiped out civilizations crumbled and nobody knew what had happened.

It was a catastrophe that affected millions of people all around the world but what was it? Was it a comet? An asteroid? A volcano? Archaeologist David Keys reveals the latter is to blame for the Dark Ages of famine and plague that shaped the world order of today.
