Her eyes flicked left and right, and a new well of fear opened within. Running with her were dozens of feeders, come out of nowhere in the rainy gloom, faceless squat shapes keeping pace as they darted through the trees, eyes filled with excitement and anticipation.

She glanced over her shoulder and saw the demon closing fast, its black shape stretched out low to the ground and hurtling forward. A surge of adrenaline propelled her ahead, and for a few seconds she managed to increase her speed enough to put a little more distance between them. But then the beast was closing on her again, and she could see the gleam of its teeth and eyes in the misty gloom.

Ahead and to her left, there were only more trees and darkness. To her right, beyond the low rail fence, the cliff fell away into a void. There were lights from houses and streets, but they were distant pinpricks through the woods, still far, far away.

She knew she was not going to escape. She was fit and strong; she was a world-class distance runner. But the thing pursuing her was too much for any human. She faltered slightly, preparing to turn and fight. The demon burst out of the night, a silent black predator, gathering itself to strike. She saw it clearly, revealed for just an instant in a patch of gray light, some sort of monstrous hyena, all neck and blunt muzzle, with huge jaws and rows of teeth. She swerved through the trees and out again, scattering feeders everywhere, trying to throw the demon off, but it was quick and agile, and it followed her easily.

“Nest, no!” she heard Ariel scream a final time, turning.

The demon caught up to her at a wide spot where the trail took a slow bend to the left, away from the cliff. She looked back and saw that it was right on top of her. She watched it gather itself, preparing to bear her struggling and helpless to the ground. Her fear enveloped her like a death shroud, choking off her breath, suffocating her. Something wild and fierce blossomed inside her in response, and for just an instant she thought it was her magic, trying to break free. But her mind was frozen by the demon’s closeness, by the gleam of its yellow eyes and the certainty of what was going to happen next, and she could not find a way to help it.

Feeders streamed through the trees, leaping wildly, shadows with eyes, gathered for the kill.

But as the demon lunged for Nest, rising up against the night, Ariel threw herself into its path, a white blur against the dark, and collapsed around its head like a child’s bedsheet. Demon and tatterdemalion went down in a tangled heap, rolling over and over on the muddied earth. Nest backed away, staring in horror at the thrashing dark knot. In seconds all that remained of Ariel was a silken white shroud that clung tenaciously to the momentarily blinded demon.
