"Unnatural Migration"
*Eighty million years into the Earth's Cretacous period, a comet destined to strike the northern continent is redirected by less than a single degree. The huge rock instead collided with the orbiting moon, saving the oblivious dinosaur kingdom below from their extinction and dooming the emerging mammals to a harsh co-existence with the huge reptiles.
Our story begins sixty-five million years later, after thousands of generations of mammals and dinosaurs finding a way to live side-by-side. *Source: Neozoic #1
