You escape but not unscathed
Ouch! Its teeth nip at your calves. Clothes tear and then there’s pain. It’s like someone’s sinking a searing blade into your flesh.
You fall to the ground and land on something hard. A stone. Grabbing it, you throw it at the hellhound and manage to hit one of the three heads. Just for a moment, the beast lets go of you. You don’t need another invitation. No matter how much that leg hurts, you run and you drag that bloody mess with you.
You don’t think you can actually escape, but just then, a group of teenagers runs past you and engages the creature in a fight. They’re crazy. The beast will tear them apart. But it won’t tear you apart, because you’re getting the hell out of this forest. And this town.
