The original home planet lost for ever:
“The loss of Tiamat, and the lives which were also lost, constitute what we call the First Loss. This event took place around 65 million years in the past of your time. Your race caused that loss and all subsequent events.”

“From the iridium measurements in the clay, the concentration of iridium in so-called chondritic meteorites and the surface area of the Earth, Luis calculated the mass of the asteroid to be about 300 billion metric tons. He then used various methods to infer that the asteroid had a diameter of 10 ± 4 kilometers (km).
Hell on Earth
The asteroid crossed the atmosphere in about one second, heating the air in front of it to several times the temperature of the sun. On impact, the asteroid vaporized, an enormous fireball erupted out into space, and rock particles were launched as far as halfway to the moon. Huge shock waves passed through the bedrock, then curved back up to the surface and shot melted blobs and bedrock out to the edge of the atmosphere and beyond. A second fireball erupted from the pressure on the shocked limestone bedrock. For a radius of a few hundred kilometers or more from ground zero, life was annihilated. Further away, matter ejected into space fell back to earth at high speeds—like trillions of meteors—heated up on re-entry, heating the air and igniting fires. Tsunamis, landslides, and earthquakes further ripped apart landscapes nearer to the impact.
Elsewhere in the world, death came a bit more slowly.
The debris and soot in the atmosphere blocked out the sun, and the darkness may have lasted for months. This shut down photosynthesis and halted food chains at their base. Analysis of plant fossils and pollen grains indicate that half or more plant species disappeared in some locations. Animals at successively higher levels of the food chain succumbed. The K-T boundary marks more than the end of the dinosaurs, it is also the end of belemnites, ammonites, and marine reptiles. Paleontologists estimate that more than half of all the planet’s species went extinct. On land, nothing larger than 25 kilograms in body size survived.
It was the end of the Mesozoic world.”
“Tiamat finally exploded, and the shock disrupted the stability of the solar system. Some from your race left Tiamat in time and survived. Eridu was their destination, a home away from home.”
Massimo Marino is a scientist envisioning science fiction. He spent years at CERN and The Lawrence Berkeley Lab followed by lead positions with Apple, Inc. and the World Economic Forum.
Massimo currently lives in France and crosses the border with Switzerland multiple times daily, although he is no smuggler.
As a scientist writing science fiction, he went from smashing particles at accelerators at SLAC and CERN to smashing words on a computer screen.
