Royal Woods: 65 million years ago
It's the end of the Cretaceous period; the last period of the Mesozoic era. The world during this time is much hotter, the Himalayas don't exist, and mammals are no bigger than rodents.
In this time Royal Woods was once dominated by one of the most successful animals that lived on Earth; the dinosaurs. During this time the dinosaurs have reached the peak of their evolution, they've spread all over the globe keeping mammals small.
Down below where the Loud house would eventually be built. A herd of triceratops graze on the ferns, while nearby a family of tyrannosaurus were eating on a edmontosaurus they've recently caught. The younger ones had chased it down while the adults used their strength to bring the herbivore down, nearby a pack of dromaeosaurus stay a good distance away, waiting for the large carnivores to eaten their fill.
The pack don't dare to get in too close, they just have to hope that the tyrannosaur family would leave enough meat for them. The members of the triceratops herd also kept a watchful eye on the large predators, but unaware for all of them their lives well change forever.
A bright light appears from the south, both predator and prey look at the blinding light until it fades in uneasy silence. What fallows next was a series of catastrophes that will lead to their extinction.
The bright light had came from an asteroid that slammed into the Yucatan peninsula. In an instant a long era had ended, and out from the ashes rose the mammals which replaced the dinosaurs as the dominant species.
Humanity soon rises, and many years later the bustling town of Royal Woods has been build. The Louds along with their friends and family live out their lives peacefully, however their peaceful way of life will soon be forever changed as the universe has long since planned its second strike.
In space; an asteroid that's slightly bigger than the one that killed the dinosaurs is drifting in the vast cosmos. The enormous rock just got knocked out of the asteroid belt, it moves in one direction towards the ever vastness of space.
A smaller asteroid about the size of the statue of liberty approaches from its left at about 300mph. It hits the bottom tip of the larger one, causing both to change directions, the smaller one heads in the direction of the sun, while the larger one heads straight in the direction of the only planet in our solar system that harbors life.
The planet Earth.
