You are in the floodplains of Europe, 150 million years ago.

The air in the lush Jurrassic floodplains of Portugal was humid and heavy. You were crouched behind a cycad fern, watching a Allosaurus cautiously edge away from a freshly killed young sauropod.

Suddenly, a massive, muscular form erupted from the ferns, tearing through the foliage with impossible speed for its size. A Torvosaurus has arrived. It was easily 10 meters long, its snout dark with dried mud, and its jaw, filled with fewer but massive teeth, hung slightly open. The Allosaurus didn't stand a chance.

The Torvosaurus—the absolute king of this European valley—roared, a sound that shook the very ground you were hiding on, causing the smaller Allosaurus to abandon its prize and flee into the dense ferns, leaving the massive predator to claim its, or perhaps its victim's, next meal.
