So we've been taught that the birthplace of the human race is Earth. But it's not. It's actually a planet in the Cunabulum System called Orous. A little of over a billion years ago Earth was discovered during what is called The Great Expansion. At the time Earth was inhabited by a branch-species of Saurisapian, a dangerous human predator called the Sargorn. Obviously before any colonization or ressource development could be done safely to Earth, a large-scale extinction event was manufactured. Edit 18 days later: [spoiler]It's a movie quote.[/spoiler]
