The event happened 65 million years in the past, when an asteroid six miles wide struck the Yucatan Peninsula in Mexico, leaving a crater more than 100 miles across. The impact — 2 million times more powerful than the biggest bomb mankind has ever ignited — created a storm of hellish proportions that blanketed the atmosphere with super-heated dust, ash, and steam.
Bits of the asteroid and the impact crater ricocheted out into space, and were pulled back to earth in a rain of molten burning stone that baked the land and started wildfires across the globe. The sky filled with toxic fumes. Acid rain fell around the world. The dense particulate cover kept sunlight from reaching the earth’s surface.
In an instant, the entire face of the planet changed. Millions of species died out in the aftermath, including the vast majority of the reptile population... and the Lizard Kings themselves.
