You are in the woodlands of North America, 75 million years ago.

The ferns of the late Cretaceous Alberta forest were damp, the air thick and warm. You crouched behind a fallen conifer, watching a herd of small, two-legged creatures bustling through the undergrowth. They were Stegoceras—plant-eaters no bigger than a large dog, but appearing incredibly stout and alert.

One individual, likely an adult male with a particularly polished, thick dome on its head, paused its feeding to sniff the air. It was a fascinating mix of delicate herbivore and armored beast, adorned with small horns along the back of its thick, bone-headed skull.
