The hour was later than he had reckoned, the round-bellied moon not yet visible beyond the Vale’s far steep, but turning the deep blue evening sky to gleaming slate in the east. On the valley floor below, the herd already formed a rudimentary circle. Ahead of him, the pied mare pitched abruptly to a halt. Lock-kneed, snorting, Jan followed suit. Korr, the king, stood on the hillside just below them. Jan tensed as his massive sire advanced through the gathering gloom.

“Greetings, healer’s daughter,” Korr rumbled.

“Greetings, my king,” Tek answered boldly. “A fine night for Moondance, is it not?”

Jan felt himself stiffen at the black king’s nod. He barely glanced at Jan.

“It is that,” Korr agreed, “and a fine eve to precede your courting trek.” The healer’s daughter laughed. Pale stars pricked the heavens. The unseen moon was washing the dark sky lighter and yet more light. “Faith, young mare,” Korr added in a moment, “I’d thought to see you pledged long before now.”

Jan felt apprehension chill him. He had always dreaded Tek’s inevitable choosing of a mate. The prospect of losing her company to another filled the young prince with a nameless disquiet—the pied mare would doubtless be long and happily paired by the time such a raw and untried young stallion as he ever won a mate. Restless, he pawed the turf, and his companion glanced back at him with her green, green gryphon’s eyes.

“Fleet to be made warrior, but slow to wed, I fear,” she answered Korr. “Perhaps this year, my king.”

The eastern sky turned burning silver above the far, high crest of the Vale.

“But I will leave you,” she continued, “for plainly you did not wait upon this slope to treat with me.”

Tek shook herself. Korr acknowledged her bow with a grave nod as she kicked into a gallop for the hillside’s base. Still paces apart, Jan and his sire watched the healer’s daughter join the milling herd below.

“A fine young mare,” murmured Korr. “Let us trust this season she accepts a mate.”

Jan felt a simmering rush. “Perhaps I’ll join her,” he said impulsively.

Korr’s gaze flicked to him. “You’re green yet to think of pledging.”

Jan shrugged, defiant, eyes still on Tek. “I was green, too, to succeed you as prince,” he answered evenly. “But perhaps I shall be Tek’s opposite: slow to be made warrior, yet quick to wed.”

The sky in the east gleamed near-white above the far slope. Korr’s expression darkened. “Have a care, my son,” he warned. You’ve years yet to make your choice.”

The young prince bristled. Behind them, Dagg cantered from the trees and halted, plainly taken by surprise. He glanced from Korr to Jan, then bowed hastily to the king before continuing downslope. The young prince snorted, lashing his tail. The king’s eyes pricked him like a burr.

“Be sure I will choose when I know myself ready,” he told Korr curtly and started after Dagg.

His sire took a sudden step toward him, blocking his path.

“If it be this year, my son,” he warned, “then look to those born in the same year as you. Fillies your own age.”

Astonished, Jan nearly halted. By Law, not even the unicorns’ king might command their battle-prince. Angrily, he brushed past Korr. “Do you deem your son a colt still, to be pairing with fillies?” he snapped. “A bearded warrior, I’ll choose a mare after my own heart.”

He did not look back. White moonlight spilled over the valley floor as the herd before him began to sway, the great Ring shifting first one way, then the other over the trampled grass. Jan’s eyes found his mother, Ses, among the crowd. Beside the pale cream mare with mane of flame frisked his amber-colored sister, Lell: barely a year old, her horn no more than a nub upon her nursling’s brow. Korr cantered angrily past Jan, veering to join his mate and daughter as the dancers found their rhythm, began to turn steadily deasil.

Jan hung back. Dagg’s sire and dam moved past: Tas, Korr’s shoulder-companion, like his son a flaxen dun dappling into grey; Leerah, white with murrey spots, danced beside her mate. Jan spied his granddam Sa farther back among the dancers. Dark grey with a milky mane, the widowed mate of the late king Khraa whickered and nodded to her grandson in passing, placing her pale hooves neatly as a doe’s. Jan dipped his neck to her, but still he did not join the Ring.

Other celebrants swirled by, frolicking, high-stepping, sporting in praise of Alma under the new-risen moon. The circling herd gained momentum, drawing strength from the moonstuff showering all around; the white fire that burned in the bones and teeth, in the hooves and horns of all unicorns, placed there by the goddess when, in fashioning her creatures at the making of the world, she had dubbed the unicorns, as favored sons and daughters, “children-of-the-moon.”

Tek swept into view, pivoting beside the healer Teki. The black and rose in her coat flashed in the moonlight beside the jet and alabaster of her sire. Tek’s riant eyes met Jan’s, and she tossed her mane, teasing, her keen hooves cutting the trampled turf, daring him to join her. Daring him.

In a bound, the young prince sprang to enter the Ring. Bowing, Teki gave ground to let Jan dance beside his daughter. The two half-growns circled, paths crossing and crisscrossing. Dagg drifted near, chivvying Jan’s flank. Jan gave a whistle, and the two of them mock-battled, feinting and shoulder-wrestling.

Tek’s eyes flashed a warning. Jan turned to catch Korr’s disapproving glare. Reflexively, the young prince pulled up. Then, blood burning beneath the skin, Jan shook himself, putting even more vigor into his step. Moondance might have been a staid and stately trudge during his father’s princely reign—but not during his own! Dancers chased and circled past him in the flowing recurve of the Ring. He found his grandmother beside him suddenly, matching him turn for turn.

“Don’t mind your father’s glower.” The grey mare chuckled. “It nettles him that it is you now, not he, who leads the dance.”

Jan whinnied, prancing, and the grey mare nickered, pacing him. They gamboled loping through the ranks of revelers until, far too soon, the ringdance ended. Moon had mounted well up into the sky. All around, unicorns threw themselves panting to the soft, trampled ground, or else stood tearing hungrily at the sweet-tasting turf. Fillies rolled to scrub their backs. Dams licked their colts. Foals suckled. Stallions nipped their mates, who kicked at them. Jan nuzzled his grandmother, then vaulted onto the rocky rise that lay at the Circle’s heart.

“Come,” he cried. “Come into the Ring, all who would join me on the courting trek.”

Eagerly, the unpaired half-growns bounded into the open space surrounding the rise. Behind them, their fellows sidled to close the gaps their absence left, that the Circle might remain whole, unbroken under the moon. Jan marked Tek and Dagg entering the center with the rest.

“Tonight is Summer’s Eve,” he cried. “The morrow will be Solstice Day. Before first light, as is the Law, all unpaired warriors must depart the Vale for the Summer Sea, there to dance court and seek our mates. There, too, must we treat with the dust-blue herons, our allies of old, who succored our ancestors long ago. But mine is not to sing that tale. One far more skilled than I will tell you of it. Singer, come forth. Let the story be sung!”

Jan descended the council rise as the healer Teki rose to take his place. The singer’s black-encircled eyes, set in a bone-white face, seemed never to blink. Jan threw himself down beside Dagg as the pied stallion began to chant.

“Hark now and heed. I’ll sing you a tale of when red princess Halla ruled over the unicorns….”

Restlessly, Jan cast about him, searching for Tek. He spotted her at last, nearly directly in front of him, eyes on her sire. Contentedly, Jan settled down to listen to the singer’s fine, sonorous voice tell of the defeated unicorns’ wandering across the Great Grass Plain. After months, Halla’s ragged band stumbled onto the shores of the Summer Sea, watched over by wind-soaring seaherons with wings of dusty blue.
