You are in the grasslands of Africa, 20 million years ago.

The air in the Miocene savannah was thick, smelling of wet earth and distant rain. You were tracking a herd of Prodeinotherium—early elephant relatives—across a wide, grassy plain flanked by volcanic hills. The sun was merciless, making the horizon tremble.

It didn't appear with a roar. It appeared with silence. One moment, the savanna was teeming with life. The next, a heavy stillness descended. Even the buzz of insects ceased. You shifted behind a cluster of acacia shrubs and looked toward a rocky ridge.

There.

It was moving along the ridge, its sheer size halting your breath. This was a Megistotherium. It was not a cat, nor a dog, but something far more intimidating—a massive creodont. It stood nearly five feet tall at the shoulder, with a gait that suggested terrible power. As it turned its head toward the breeze, you could see the disproportionate massive head with terrifying, specialized shearing teeth designed for crushing bones, not just tearing flesh. Its two feet long snout was strangely wide, accommodating the canine teeth that could likely shatter a rhino leg.

You are witnessing the supreme apex predator of its time, as the creature descended from the rocky outcrops with surprising agility, and begins to move towards the herd of the early elephants below.
