You are in the forests of Europe, 215 million years ago.

The heat in this arid basin is stifling. The air smells of dust, dry ferns, and something else—a musky, heavy scent. You pressed yourself against the bark of a towering conifer, your breath catching in your throat. It wasn't the heat of the Triassic sun that made you sweat; it was the shaking ground.

Through the dense foliage of cycads and ferns, you saw them—a herd of Plateosaurus, easily fifty strong, passing through the clearing.

They were massive, far bigger than you imagined. The adults walked on two powerful legs, their long, flexible necks swaying as they scanned for food. They didn’t roar; instead, they made low-pitched, almost bird-like bellows to each other as they moved. The smaller, younger ones stayed tucked safely in the center of the herd, surrounded by the towering adults.

One of the largest males paused not twenty feet away, its sharp, leaf-shaped teeth clipping branches effortlessly. It turned its small head towards you, grasping hands with massive, curved claws tearing at the fern roots. The giant seemed indifferent, simply a plant-eating titan focused on feeding. As they marched on, the sun-dappled forest floor vibrated, leaving you stunned by the sheer scale of the new world you had stumbled into.
