Actually, Sesshomaru was hungry.
He wandered through a skeleton forest for some distance, then decided to sit on a boulder. Still as stone, he waited patiently beside a snow hare's borrow until one emerged. He seized the unlucky creature, breaking its neck in the same swift motion.
The sky was darkening. The moon disappeared behind the clouds.
A freezing wind gusted, snapping branches and tearing needles free from the pines, pricking them at his brow and face. A flake of snow, and then another. But he ignored the snow falling on him, as he pulled the hare's flesh from its steaming hide.
