Beast-mode, activate!

The wind howled outside the cave as it blew torrents of snow just through the entrance. Inside a fire had been lit in a primitive fashion using stones and moss. It flickered weakly, providing little warmth and filling the air with a putrid odor. A pale and fairly emaciated figure huddled near to it, limbs wrapped over frame in an attempt to hold the heat in.

The blizzard had raged for days outside and Shiki had wandered too close to the mountains in an area he was unfamiliar with. There had been little food to find out there and as such he had not eaten since even before the blizzard had started. The hunger fueled the natural animalistic nature belonging to the hollow, but it grew far outside the scope of an arrancar, delving back to the days of being an adjuchas for Shiki. His eyes were wild and they were not the only change that was overcoming him, for as his mind devolved, so too did his body, returning to what it once was.

The wind wasn't the only thing howling for long.
