They move in a halting, jerking cadence, head tipping at one angle, then another, peering into the depthless black, triangulating the low sounds of that damaged, snarling thing as it goads them, taunts them, eager to re-engage.

They crouch low, one palm to the smooth nothingness at their feet as they gather themselves like a great raptorial cat balancing all its weight on its haunches. They rock, a slight, subtle shift of weight on their feet from one leg and to the other, until they surge forward, source of the noise pinpointed.

This time, they duck out of the way from it before their bodies meet in a clash of wild and reckless weight, roll smoothly, cutting a wide arc around it to hit it from the side in a tackling pin.
