Fog! Sturm stood upright in the stirrups. While he was wool-gathering, the mare had stopped on the greenway, serenely eating the path in front of them.

Tendrils of mist, unnaturally pale, rose like spirits out of the plains around him. The sun was oblique and muted. The air was white, gray at the greater distances where the rising mist blocked the sunlight altogether.

Sturm leaned forward and squinted, his hand on his sword. So it wasn't evening, after all, but a deep fog. He clucked his tongue at the mare, and warily Luin began to move again, placing one foot cautiously before the other as though she walked through a swamp or along an unsteady precipice.

Then music rose out of nowhere, an old hornpipe in a minor key. Sturm drew his sword and wheeled about in the saddle, but everywhere was mist and music, and nothing more than that. At once he felt foolish, as if he had drawn his sword to fight the air.

"Come out, Vertumnus!" Sturm muttered, his voice rising with his anger. "Get out from behind your fog and nonsense, and let's settle this. Sword to sword, knight to knight, man to man!"

But the music continued serenely, perpetually, the tune varying and doubling back on itself, always recognizable and yet never the same. The fog began to dance to the music, swirling and shifting in a mad, encircling reel. Now Sturm could no longer see the ground. It was as though Luin waded through shallow, indefinite waters.

Cautiously the lad dismounted and walked beside his mare, each step light and doubtful. He could no longer feel the newly grown grass, and he was beginning to wonder if the ground itself had turned to mist.

"The keep… is Vingaard Keep to the left? The setting sun…" Sturm muttered. Directions were useless now, even if he could remember them in the midst of this infernal, confusing music. The rules of the road were changing rapidly, and he hated himself for being already lost.

For an hour or so, Sturm trudged on through the murk, his path winding hopelessly and his thoughts slipping from bewilderment into alarm.

Quite abruptly, the music stopped. The silence that followed was again breathless and hostile, as though the plains themselves were hushed in the expectation of some terrible crime. Sturm felt his sword shake in his hand.

For a few minutes, he continued his wandering, his steps even more tentative. The hooting of an owl in a blasted oak sounded like a call from the land of the dead, and once or twice the lad thought he heard a baby crying nearby. The sounds brought him dangerously close to panic. Twice he set foot to stirrup but both times gathered his wits and thought better of it.

" 'Tis all you'd need!" he whispered angrily. "A nasty fall from a horse in a deep fog! Crack your skull and drive out what little brains you have left!"

Finally, suspecting that he might even be headed back toward the Tower, Sturm decided to stop and wait out the fog. "For wouldn't it please Derek Crownguard," he asked Luin, "if I were simply to walk out of the mist in front of the great southern gate, having turned myself entirely about in a terror?"

He gritted his teeth. "By Huma!" he swore, "I'd rather die than give that scoundrel a moment's triumph!"

Luin rolled her long nose over the lad's shoulder and nibbled his hair thoughtfully.

Together the two of them waited, old mare and young rider. They dozed, startling awake now and then at the wingbeat of quails, at the chittering sound of squirrels in the distant trees. Finally the evening approached, and the country fell hushed and settled around them.

Sturm awoke with a start. For a moment, he thought he was back in the Clerist's Tower, safe in the squires' barracks. But he was armed and cloaked, and his bed was open ground. He turned over and blinked stupidly, remembering at once where he was.

"Luin!" he whispered. The mare had wandered off, but she was somewhere nearby. Through the early morning darkness, he heard her, sniffing and pawing the earth. Sturm struggled to his feet, his father's breastplate unwieldy and too heavy to balance. Reeling one last time, the lad righted himself and stalked off in the direction of the sound.

Suddenly there was a gentle rustling on the breeze, a sound he would remember at once when he heard it years later in the ruins of Xak Tsaroth. At first he thought it was a storm wind coursing through the leaves, but the air was still. Sturm thought of Vertumnus, of the unnatural change of the seasons…

He stumbled forward as a hot breeze passed over him, carrying upon it a smell of sulfur and ash and anger. At first it seemed as if the plains were burning, that the mist was igniting around him. He was choking.

Sturm spun about, whistling frantically for Luin. The mare emerged calmly out of the mist and the curling smoke, stopping only to browse lazily at a low clump of clover. He scrambled to her side, hoisted himself onto her back…

And held on for dear life as Luin caught wind of something beneath the sharp smell of the air, a greater, more sinister terror. She kicked out instantly, hysterically, and galloped into the mist.

Sturm clung to the reins, his ankle tangled in a stirrup. Vainly he tried to wrestle up into the saddle, but Luin's wild and headlong path through the fog carried both of them over rough terrain, and it was all he could do to hold on. Behind him, the rustling sound faded, then resurged, this time far louder. It sounded like nothing the lad had heard before. He thought of cyclones, of the fierce Aferian wind that rides through mountain passes, leveling tree and house as it rushes onto the plains. Faster Luin galloped, her chestnut coat slick and flecked with foam now, and still the great noise closed on them, louder and swifter and more urgent.

Sturm thought of reaching for his sword, of turning to face whatever it was that Vertumnus had sent after him. But Luin kept galloping like a wind herself over the Solamnic Plains. To remove one hand from the reins would risk a broken neck or back, a fatal dragging over the hard ground. He hung on, then, slinging his leg over the saddle once, twice, a third time, but the speed of the horse and the weight of his armor kept him dangling and struggling, unable to recover his balance. The mist behind him began to glow with a menacing, blood-red light, and in the heart of the light, a huge dark shape swooped toward him on leathery batwings, and the air was hot and hotter still until the heat was intolerable.

And suddenly, unexpectedly, the music returned, the fog closed around them, and the light bent away from him, taking with it the sound and the heat. Coughing, gasping, halfway atop the mare, Sturm watched the mist open up and swallow the hulking, leathery form of the pursuer. The heat and the roaring subsided.

And the music echoed in the rocks around them. A different tune this time-a quickstep filled with deception and comedy, so contagious that the nightingales perched in the darkened boughs of oak and vallenwood began to trill and mimic in answer. Luin slowed to a canter, to a walk, and Sturm, winded and baffled, finally settled himself on her back.

"By Branchala, that was a strange thing!" the young man muttered. He looked around him as the mist scattered, falling like rain back into the hard, spare ground. Above him, the stars appeared in the Solamnic night sky-first the moons, then bright Sirion and Reorx. By their reckoning, he was miles south of where he had been.

"What… what was it, Luin?" he asked. "And… where are we?"

The mist had subsided now, and from horseback, Sturm could see some distance across the level plains. A village lay in the distance to the west, its faint lights twinkling in the clear winter night. It was an inviting prospect-warmth and shelter for whatever time remained before sunrise.
