You are a horse.

You race over the plains, the wind flowing through your mane. Your hoofbeats are rhythmic as you follow your herd through the prairie. The sun casts warm rays over your flank. Your herd races across the plains, frolicking and enjoying the freedom. Eventually, the herd slows and rests amongst a lush clearing, grazing on prairie herbs. As you run, you notice a figure on top of a nearby hill. It's a human, Alex Spencer, on horseback. He seems to be scouting your herd.
