Conditional Reality

In our village we always loved the unicorns that lived on the nearby plains. Some years ago a neighboring village began to hunt them. They believed that by grinding up unicorn horns and eating the dust they would become smarter, braver, and more beautiful. Soon the unicorns had only a few surviving individuals. We asked if we could ride them to safety. They agreed. We abandoned our village and traveled on unicorn backs to the mountains. We have lived here ever since. The hunters sometimes come to the mountains. We hide from them. The unicorns study them with unblinking eyes.
