The night air is still and cold on the hilltop. Above, a spray of stars spills across the sky, their light catching the twisted branches of a giant, withered oak. Beneath it stands a skeleton, his form veiled in shifting black substance, tendrils writhing from his spine. He hasn't seen you yet. But the air changes as the darkness seems to turn, slowly, in your direction.
