The Whispered Scream
Every dome on Murd has at least five barn owls, or we'd all be dead by now.
I can still remember being out in the fields with Mom, taking soil samples, or was that later? I wouldn't have been old enough to help take soil samples the first time I ever remembered hearing the barn owl. At any rate, once you've heard it, you never forget it: a long screaming siren, beckoning the field workers to get back to the dome as quickly as possible. It's a terrifying, unmistakable noise, and it's meant to be... evidently they modeled the sound (and the name) after a kind of Earth bird. A nocturnal bird, that only wakes up when night is coming.
