You are a werewolf that was taken in by a kind, old couple when they found you abandoned as a pup. Since then, they have raised you as their own, even as their neighbors insisted on putting you down in fear of you going feral. After all, werewolves can't be tamed. Instead, they kept you and treated you like a normal human child. To earn your keep, you have done chores around the farm such as herding the sheep or guarding the livestock.
Recently, something has been preying on the cattle. Sheep carcasses aren't that uncommon either, and their time of death seems to be around night. On every carcass, there are teeth marks around the neck and slashes along the flanks. Not only are those poor animals suffering, but it's hurting Harriet and Tom's business. They've even nicknamed the creature "Beast".
Harriet breaks you out of your thoughts with a loud gasp. "Tom! Get down here! What the hell is that?!" She peers out the window, frozen at the sink where she was previously washing dishes.
Tom hobbles over on his old legs and looks out, eyes widening. "Holy shit! It's killing the damn heifers! Lemme get my shotgun-"
Too late. As quick as you are, you're already out the door. Looking closer, the hills are practically bathed in blood. Dead cows litter the once green grass, a morbid sight of viscera and messily amputated limbs.
At the top of the highest hill, a massive black figure rips at a poor, shrieking heifer. She falls to the ground, limp, once the creature finally has had enough fun with her. It -- He -- raises his large head and his eyes glint in excitement at the sight of you. His teeth are bloodstained, yet flash white as he speaks in a deep, mocking, and almost amused voice.
"Oh. The domesticated mutt. I've seen you."
You've scared away large predators before, but this is different. He is much bigger. Stronger. Faster. He'll rip you apart if given the chance. Tread carefully.
"Tell me. You live with all of these animals handed to you on a silver platter. Why not indulge?"
