At the fore rode a rider whose wings shone with the hard iron fletching of griffin feathers. Like the others he wore a metal visor shaped and forged into the likeness of a face, blank and intimidating, but Zacharias did not need to see his face to know who it was.

Bulkezu.

The name struck at his heart like a deathblow.

A band of fifteen riders approached the ring of stones, slowing now, the hum of their wings abating. From a prudent distance they examined the stone circle and split up to scout its perimeter and assess the stone portals, the lay of the ground, and the strength of its defenders. The horses shied at first, made skittish by the great hulking stones or by the shadow of night that still lingered inside the ring, but taking courage from their masters, they settled and agreed to move in closer.

The woman braced herself at the eastern portal with her spear in one hand. She showed no fear as she waited. The riders called out to each other. Their words were torn away on a wind Zacharias could not feel on his skin—audible but so distant that he could make out no meaning to what they shouted to each other, as though the sound came to him through water.

At once the whirring began again as all the riders kicked into a gallop and charged, some from the left, some from the right, some from the other side of the circle. Wings hummed; hooves pounded; otherwise they came silently except for the creak and slap of their armored coats against the wooden saddles.

With the rising sun bright in his eyes, Zacharias saw Bulkezu as iron wings and iron face and gleaming strips of iron armor. The two feathers stuck on either side of his helmet flashed white and brown. The griffin feathers fletched in the curving wooden wings that were fastened to his back shone with a deadly iron gleam. Where the ground leveled off, just beyond the eastern portal, he galloped toward the waiting woman, lowering his spear.

Zacharias hissed out a breath, but he did not act. He already knew he was a coward and a weakling. He could not stand boldly against the man who had first mocked him, then violated him, and then wielded the knife.

He could not stand boldly—but he watched, at first numb and then with a surge of fierce longing for the woman who waited without flinching. With an imperceptible movement she opened her fingers. From within her uncurling hand mist swirled into being to engulf the world beyond. Only the air within the stone circle remained untouched, tinted with a vague blue haze. An unearthly fog swallowed the world beyond the stones.

All sound dissolved into that dampening fog, the whir and hum of spinning feathers, the approach of the horses, the distant skirl of wind through grass.

With a sudden sharp exclamation, the woman leaped to one side. A horse loomed, became solid as griffin feathers cut a burning path through the mist. In stillness the horse jumped out of the fog and galloped into the ring of stones, hooves clattering on pebbles. Bulkezu had to duck so that his wings did not strike the lintel stone above.

The other riders could be seen as fleeting figures searching for a portal to enter, yet they were no more substantial than fish swimming beneath the cloudy surface of a pond. They could not leave their fog-enshrouded world. They could not enter the circle.

The war leader quickly scanned the interior of the stone ring, but the woman had vanished. As he turned his horse in a tight circle the griffin feathers left sparks behind them in the blue haze. Of all things in this place, those feathers alone seemed immune to the witchcraft that had been brought to life.

“Dog!” he called, seeing Zacharias through the haze. “Crawling one! You have not escaped me!” He nudged his horse forward, tucked his spear between leg and horse’s belly, and drew his sword. Zacharias shrank back, trapped against the stone. He had nowhere to run.

But the horse had taken no more than three steps when the earth began to shake and the huge stones groaned and creaked and seemed to swing wildly from side to side, although Zacharias felt nothing at his own back except solid, unmoving stone. Bulkezu’s horse stumbled to its knees, neighing in terror, and Bulkezu himself was thrown. Stones swayed as if whatever spell had set them in place was at this moment unweaving itself, and Zacharias shrieked, flinging up his hands to protect himself, although mere flesh could not protect him against stone.

This was more than witchcraft.

The woman appeared again in the center of the circle, surefooted and unshaken by the earth’s tremors except for the flashing shimmer and sway of beads dangling among her gold necklaces. Bulkezu struggled up from his hands and knees behind her. Zacharias tried to call a warning, but the breath sucked into his lungs congealed there and he could only gasp and choke and point.

With a grunt, the woman swung around to bring the flat of the obsidian blade down between the two arched spines of Bulkezu’s wings, onto his head. The blow laid him flat on his stomach, and his helmet canted awkwardly to one side, almost torn off. Blood swelled from the base of his skull to mat his black hair. The shaking subsided, but the haze remained. Outside the circle the other riders flitted by this portal and that, still searching for an entrance.
