The bitter taste of fresh laurel leaves lingered on Callista’s tongue, sharp and astringent, like chewed bark soaked in sea brine. She had been instructed by the Elder Pythia to chew three leaves at sunrise, no more, no less, and to swallow the dark green mash down to the last fibrous vein. It was supposed to prepare the mortal stomach for the god’s voice. In practice, Callista found, it mostly prepared the mortal stomach for nausea.

She sat upon the edge of the limestone ledge in the courtyard behind the Temple of Apollo, watching the gray predawn mist cling to the lower slopes of Mount Parnassus. Below, in the valley of Phocis, the silver expanse of the olive groves slept beneath a cold, pearlescent haze. From this height, Delphi seemed pinned between the stony ribs of the mountain and the yawning air above the Gulf of Corinth. The air carried the scent of wet shale, woodsmoke, and the mutton tallow burning in the eternal flame within the temple.

"If you throw up on the flagstones, Callista, the junior acolytes will have to scrub them with vinegar before the priests of the Hosioi arrive," a voice called out.

Callista did not need to turn to know that Timon was walking toward her. He had the annoying habit of dragging his left heel, a souvenir from a childhood tumble into an irrigation ditch in Kirrha. He carried two clay cups that steamed faintly against the chill morning air.

"I am not going to throw up," Callista said, swallowing hard against the bitter saliva pooling beneath her tongue. "The god demands obedience, not a weak stomach."

"The god isn't down here scraping goat fat off the bronze braziers," Timon said, handing her one of the cups. It contained watered goat’s milk boiled with a touch of wild thyme. "Drink that. It cuts the sap. Old Theano told me once that the first month of chewing the laurel is always the worst. She said she spent her entire seventeenth year vomiting behind the treasuries."

"Theano was seventy when she died last winter," Callista said, taking the cup with both hands to warm her numbed fingers. "And she was legendary. Kings sent gold tripods the size of bullocks just to hear her cough three ambiguous lines about naval treaties."

"And now you have the seat," Timon said, his tone turning cautious. "Or at least, you will have it by the time the sun clears the crags."

Callista took a sip of the warm milk. It helped soothe the burn in the back of her throat, but it did nothing for the cold stone sitting in the pit of her belly. Three days ago, the lot had fallen to her. The sacred lot, drawn from a bronze urn by the High Priest Nicander himself: white bean for Callista, daughter of an unremarkable goatherd from the hill country near Arachova. Her predecessors had mostly been seasoned women, matrons of quiet demeanor and unblemished repute who had lived their lives before donning the simple chiton of the maiden. But the omens had grown restless over the winter. Three heifers had dropped dead without a mark on their hides, the springs had run milky for an afternoon, and then the fever had taken Theano in a single night.

Nicander had declared that Apollo demanded youth—a vessel unclouded by the world’s accumulated memory. Callista, who had served as a temple maiden since she was eight, carrying ewers and sweeping fallen leaves from the portico, had suddenly been wrapped in unspun fleece and told she was to speak with the voice that split the rocks.

"They brought a delegation from Corinth last night," Timon said, leaning against the fluted column behind her. "They’re waiting at the lower inn. Four wealthy merchants with fat purses and bad consciences. One of them lost two grain ships off Cape Malea and wants to know if he should sacrifice a team of white horses to Poseidon or just bribe the harbor master at Lechaion."

"A simple question," Callista muttered. "The answer will likely be that he should pay his debts and pray for fair winds. Nicander can spin that into hexameters before breakfast without spilling his wine."

"It's not the merchants you need to worry about," Timon said softly. "The crows have been circling the high crags since midnight. They aren't roosting. I saw them while I was drawing the water for the morning ablutions. Just tumbling on the wind like scraps of burnt linen. It’s unnatural."

Callista looked up. The sky was turning a thin, watery blue, the color of skimmed whey. High above the temple roof, dark specks drifted against the sheer wall of the Phaedriades, the Shining Rocks. They did not call or dive; they merely wheeled in tight, silent gyres.

"Everything feels unnatural today," she said, finishing the milk and setting the cup on the stone terrace.

Footsteps echoed from the interior corridor of the temple—heavy, measured, and accompanied by the soft hiss of linen robes sweeping across polished marble. Nicander emerged from the shadow of the peristyle. The High Priest of Apollo was a tall man in his late fifties, his silvering beard clipped into precise, aristocratic curls that reflected the fashion of the Athenian courts. He held a small bronze censer in one hand, from which a thin plume of sweet-scented storax rose into the damp air.

"Callista," Nicander said. His voice was rich and deep, polished by decades of reciting sacred hymns and reassuring nervous potentates. "It is time for the lustration. The morning star has set."

Timon immediately took the empty cup, bowed his head with the practiced humility of a temple attendant, and melted away toward the kitchens.

Callista stood. Her legs felt light, almost detached from her body, as if she were stepping through shallow, rushing water. She pulled her mantle tighter around her shoulders. "Is the victim prepared?"

"A young goat, perfectly white, without a single dark hair upon its fleece," Nicander replied, his eyes assessing her face with clinical precision. "It stood quietly while we bathed it. It did not shiver when the cold water touched its ears. The god is receptive."

"And the chasm?" she asked, the question escaping her lips before she could stop it.

Nicander’s gaze hardened ever so slightly. The genial patriarch vanished for a fraction of a second, replaced by the administrator of the most powerful sanctuary in the known world. "The chasm breathes as it always does. The vapors are steady. You have been taught the chants; you know the measures. You will sit, you will inhale the sacred pneuma, and you will give yourself over to the light. Apollo does not destroy his own, child. He merely uses the reed to play his tune."

"I am not afraid," Callista lied.

Nicander smiled, a brief flash of white teeth in his graying beard. "A little fear is pious. It keeps the spine straight. Come."

She followed him down the long, covered portico toward the interior of the temple. The air here grew thick with the smells of age and ritual: the musty odor of centuries-old cedar beams, the cold tang of the stone floors, and the pungent, heavy aroma of burning dried herbs. Behind them, through the gaps between the massive Doric columns, the sun finally cracked the horizon behind Mount Cirphis, sending long, spear-like shafts of amber light cutting through the shadows.

They reached the inner sanctum, the approach to the adyton. Here, the world narrowed. Two lesser priests stood beside the heavy bronze-studded doors, their heads bowed, holding torches that sputtered with fragrant pine resin. Between them sat a stone basin filled with the water brought that morning from the sacred spring.

"Wash," Nicander commanded gently.

Callista plunged her hands into the freezing water. The shock of it made her gasp, clearing the faint dizziness left by the laurel leaves. She splashed the icy liquid over her face, running wet fingers through her hair, which was bound back simply with a wool band. She wiped her hands upon the coarse linen towel held out by an acolyte, feeling the rough texture scrape her skin. Every sense seemed heightened, almost painfully acute: the crackle of the pitch on the torches, the cold draft rising from the stone floor beneath her bare feet, the distinct scent of old bronze and ancient dirt.

The doors were pulled open with a low, grinding groan of metal hinges.

The adyton lay below the level of the temple floor, carved deep into the living rock of the mountain itself. Callista walked down the five narrow stone steps, Nicander following a pace behind. The chamber was small, subterranean, and devoid of the grand marble ornamentation of the upper halls. The walls were rough-hewn limestone, glistening in patches where mineral water wept through microscopic fissures in the rock.

In the center of the chamber stood the golden tripod. It was a tall, three-legged stool of cast bronze washed with gold, its legs ending in lion’s paws that gripped the rough stone floor. It sat directly over a fissure in the rock—a narrow, jagged crack that plunged down into darkness. From that darkness rose the pneuma, the breath of the earth.

It did not billow like hearth smoke. It rose as a shimmering, translucent haze that distorted the air above the crack, carrying an odor that was sweet and rotten at once, like overripe apples left to ferment in a sealed damp cellar, overlaid with the sharp bite of brimstone.

Beside the tripod sat a low bronze brazier filled with glowing charcoal. Upon it, a small heap of dried laurel leaves, barley meal, and frankincense smoldered, adding its own dense white smoke to the shimmering heat from the fissure.

"Sit," Nicander whispered. His voice was no longer that of the commanding priest; it was hushed, almost fearful, as if he too remembered that they were trespassers in a place older than the temple above them.

Callista climbed onto the small footstool and pulled herself up onto the seat of the tripod. Her toes dangled just above the warm lip of the fissure. The heat from the charcoal brazier struck her left side, while the cool, mineral-heavy draft from the mountain caressed her right. She held the small sprig of laurel they had placed in her right hand, her fingers curling around the waxy stem until the leaves bruised against her skin.

Nicander stepped back toward the staircase, where two scribes waited in the gloom with wax tablets and bronze styluses ready. The delegation from Corinth had not been admitted; they waited in the outer hall, where they would hear only the wild, rhythmic cadence of her cries, to be translated later by Nicander into stately, ambiguous verse.

"Lord Apollo," Nicander intoned, his voice echoing flatly against the damp rock walls. "Slayer of the Python, master of the silver bow, lord of light and truth. Thy servant sits upon the seat of prophecy. Open her ears to the music of the spheres. Pour thy light into the vessel of her flesh."

Callista closed her eyes.

She breathed in.

The first breath was pure fire. It did not fill her lungs with air, but with something heavy, sweet, and suffocating. The scent of fermented fruit surged up her nostrils, followed immediately by an overwhelming bitterness that coated her tongue. Her head spun violently, the darkness behind her eyelids exploding into spinning wheels of yellow and violet.

Breathe, she told herself. Just breathe. It passes. Theano said it passes into light.

She breathed again, deeper this time, drawing the vapor up from the cold depths of the chasm.

The sound of Nicander’s voice faded. The crackle of the brazier became a distant, muffled pop, like twigs snapping underfoot leagues away in a winter forest. The cold stone beneath her seemed to soften, to liquefy, as if she were no longer sitting upon a bronze stool anchored to the mountain, but floating upon a dark, subterranean river that had no beginning and no shore.

Then the light came.

It was not the gentle, golden dawn of Greece. It was a harsh, searing brilliance that burned through her eyelids, stripping away flesh and bone until she felt entirely naked, reduced to a spark of raw awareness tossed into a furnace.

She heard a sound. It was not music. It was the grinding of teeth, massive and stone-hard, chewing the foundations of the world.

Callista tried to scream, but her throat was locked in a spasm of sweet-scented vapor.

The vision did not come as a picture, framed and orderly. It tore through her like a spear thrown from behind.

She saw the sea. Not the calm, blue waters of the Crisaean Gulf, but a boiling, black cauldron that surged upward toward the cliffs. The ships—scores of them, their sails painted with the eyes of gods—were not sailing; they were snapping like dry pine kindling against the rocks, their hulls ground into driftwood by waves that carried the stench of old blood.

Then the vision shifted, plunging upward. Mount Parnassus was splitting down its spine.

The crags of the Phaedriades, which had stood since the titans walked the earth, were groaning. Huge slabs of limestone, white as bleached bone, broke free from the heights and tumbled through the air, crushing the treasuries, smashing the bronze statues of athletes and kings, obliterating the sacred way beneath a deluge of stone and choking gray dust.

No, Callista’s mind cried out. Not the temple. Not the god's home.

A voice answered her. It was not the serene, measured voice of the Phoebus Apollo that the poets sang of at the Pythian games. It was ancient, furious, and cracked with age. It sounded like earth grinding against earth, like a tomb being forced open by an iron bar.

The cup is full, the voice grated through her bones, rattling her teeth in their sockets. The scales are broken in the marketplace. The gold is tainted with the tears of the innocent. I turn my face away from the lyre. I bring the plow of ash.

In the blinding, scorching light, she saw a serpent.

It was not the legendary Python slain by the god in the first days of time. It was a creature made entirely of shadow, coiled not around the omphalos stone, but around the sun itself. Its coils tightened, squeeze by squeeze, choking the golden fire until the sun turned the color of bruised copper, then a dull, weeping red, like an ember dying in a pool of stale beer.

A virgin shall hold the thread, the voice hissed, closer now, breathing directly into her inner ear with the cold breath of the deep earth. A single strand against the falling rock. Find the eye beneath the eagle's foot, or let the stone return to dust.

The heat in her chest expanded until she thought her ribs would burst open like an over-baked clay pot. The sweet-sickly air of the chasm turned to needles in her throat. She saw a city—her city, the white roofs of Delphi, the tiered benches of the great theater, the modest stone cottages of her kinfolk on the high slopes—all submerged beneath a slow, relentless wave of black mud and tumbling rock. The screams of children cut through the roar of the mountain, high and thin, like the cries of gulls caught in a storm.

"Speak!"

The word came from a world she had forgotten existed. It was Nicander, demanding his verse, demanding the words he could polish into meter for the Corinthian merchants.

"Speak, Pythia!"

Callista’s eyes flew open.

The light of the torches in the adyton was blinding, yet it seemed feeble, pathetic, like the flicker of a firefly trapped in an iron pot. She could see Nicander standing at the base of the stairs, his tablet held loosely in his left hand, his face pale with a mixture of professional tension and real, sudden terror. Beside him, the two junior scribes were trembling, their styluses poised uselessly above the wax.

The room was shaking.

It was not a metaphor. The bronze tripod beneath her shuddered. The heavy stones of the adyton floor ground against one another with a dull, subterranean rumble that Callista felt through the soles of her feet. Small fragments of mortar and lime dusted down from the ceiling, fluttering through the air like pale moths.

"Callista!" Nicander stepped forward, his composure breaking. "What does the god say? What is the word for Corinth?"

Callista looked at him, but she did not see the High Priest. She saw only a man standing upon dry kindling while the torch was already falling from the sky. Her tongue felt thick, heavy as lead, and swollen with the bitter grease of the laurel.

"Not Corinth," she whispered. Her voice was raspy, stripped raw by the vapors, yet in the confined stone chamber it sounded unnaturally loud.

"What?" Nicander demanded, straining to hear over the low, vibrating hum that still rose from the fissure.

"Not Corinth," she repeated, and then the god—or whatever dark, nameless thing had seized the cavern—tore the words from her mouth in a wild, ragged cry that made the flames on the torches leap and flatten against the pitch.

"The sun is bleeding into the sea! The great rock falls! The eagle's foot is upon the eye, and the house of stone shall be a house of graves!"

She gripped the edges of the bronze tripod, her knuckles turning white. The sweet, rotten air rushed up from the chasm in a sudden, violent gust, extinguishing the smoldering coals in the brazier with an angry hiss.

"Callista, stop," Nicander hissed, glancing nervously at the scribes, who had dropped their styluses to the floor. "Control yourself. The ritual—"

"There is no ritual for this!" she screamed, the vision blinding her again with a flash of copper red. "He has thrown down the lyre! He takes the bow! The ash is coming, Nicander! The ash is coming for the priests who sell the truth for silver!"

She threw her head back, her body arching until her spine threatened to snap against the rim of the seat. The sprig of laurel dropped from her paralyzed fingers, tumbling straight down into the narrow, black throat of the chasm.

The darkness surged back, cold and absolute, rushing into her eyes, her ears, her open mouth.

Callista felt the cold bronze of the tripod slip away beneath her. She felt the sensation of falling, down through the air, down toward the jagged limestone floor, and then there was only the smell of bruised laurel leaves, the sound of stone sliding upon stone, and the total, unyielding silence of the rock.

Cold stone pressed against Callista’s left cheek. The sharp taste of copper and bruised vegetation rested heavy on her palate, accompanied by the distinct, dusty sensation of dry lime on her skin. She lay on her side at the base of the golden tripod, her chiton tangled around her knees.

Above her, the small square of light from the adyton’s upper entrance seemed miles away, hovering like a faint silver coin in the gloomy vault.

"Get her up," Nicander’s voice cut through the ringing in her ears. It was low, hard, and stripped of all its usual melodic cadence. "Before the delegation in the outer hall hears any more of this nonsense."

Strong hands hooked beneath her arms. Timon’s smell—goat’s milk, wild thyme, and sweat—settled over her like a familiar cloak as he hauled her upright. Her knees buckled immediately, her feet finding no purchase on the smooth slate.

"I’ve got her, my lord," Timon murmured, his grip tightening around her ribs. His hands were trembling, though whether from the effort of holding her weight or from the lingering tremor that had shaken the mountain, Callista could not tell.

"Take her to the inner treasury," Nicander ordered the scribes, who were hurriedly gathering their dropped styluses and blank wax tablets from the floor. "Not a word of this to the Corinthians. Tell them the god was pleased with their pious intention, but the air in the chasm was too thin for a full hexameter today. Tell them to return at the next new moon with three more oxen."

"And the prophecy, High Priest?" asked the older scribe, his hand hovering over his robe. "The bit about the ash? The eagle's foot?"

"There was no prophecy," Nicander said sharply. He stepped closer, his shadow falling over Callista as she leaned heavily against Timon. "The Pythia was overwhelmed by the pneuma. A maiden’s lungs are soft, easily swollen by the earth’s vapor. She spoke in the delirium of a fever, nothing more. Write down the usual blessing for fair voyages and sound investments. Now go."

discounted, the scribes scuttled up the narrow stairs, their woolen cloaks snapping against the doorframe as they vanished into the upper temple.

Nicander waited until the sound of their sandals died away before turning his complete attention to Callista. He reached out with one manicured finger, catching her chin and lifting her head until her eyes met his. The cool, calculated authority in his expression had returned, though a faint muscle twitched near his jawline.

"Can you walk, Callista?"

"The earth..." she rasped, her voice sounding like dry straw dragging across stone. "It moved, Nicander. It wasn't just the vapor."

"Mountains shift," Nicander replied dryly, releasing her chin. "Parnassus has settled its bones since the days of Deucalion. A pebble drops in a fissure ten leagues down, and the stone above sings. It means nothing."

"The serpent wasn't Python," she insisted, trying to stand on her own, though the room tilted wildly around her. "It was... something else. It was wrapping around the sun."

"It was the laurel," Nicander said flatly. "You chewed four leaves instead of three, or perhaps the morning mash was too old. Timon, fetch the wool wash and the warm water. We will clear her head before we bring her near the Omphalos."

"The Omphalos?" Timon paused near the lower archway. "My lord, the High Council is gathered in the outer precinct. The archons from Athens arrived an hour ago. They are demanding to see the Navel."

"Then they shall see it," Nicander said. "And they shall see our new Pythia standing beside it, calm, pious, and entirely silent."

He turned back to Callista, his eyes narrowing. "You will wash your face. You will put on the white linen chiton with the gold border—the one reserved for the spring festival. And when you stand before the sacred stone, you will keep your teeth together. Do you understand me, child?"

"I saw the temple in ruins," Callista whispered, ignoring his command. "The columns were snapped like barley stalks. The treasury of the Siphnians was buried in gray mud."

Nicander leaned in close, his breath hot against her ear, smelling faintly of the mastic gum he chewed to sweeten his speech. "Listen to me very carefully, Callista. Delphi exists because men believe Apollo speaks here. They bring their gold, their grain, their olive oil, and their armies because they believe this mountain is the center of the world, anchored by the god's own hand. If you go out there and tell the archons of Athens and the merchants of Corinth that the god has abandoned his hearth and promised them a grave of ash, they will not pray. They will stop paying the tithe. They will abandon the sanctuary, and the hill tribes will come down from the high crags to burn what is left."

"It isn't a lie if the god showed it to me," she protested weakly.

"The god gives us riddle-work, not death sentences," Nicander said, backing away and straightening his embroidered mantle. "It is our duty to weave his threads into something that keeps the roof over our heads. Now, clean yourself. The stone awaits."

Ten minutes later, washed and clad in stiff, unblemished white wool that smelled of crushed lavender, Callista stood at the threshold of the central sanctuary.

The inner court of the temple was flooded with the harsh, clear light of mid-morning. The gray haze that had hung over the valley at dawn had been swept away by a stiff wind blowing off the Gulf of Corinth, leaving the air crystalline and sharp. Columns of golden pentelic marble cast long, blue-tinged shadows across the paved floor.

In the middle of the courtyard sat the Omphalos—the Navel of the Earth.

It was a egg-shaped stone of white marble, roughly three feet high, covered entirely by a carved woolen net pattern, the agrenon. According to the stories told to every acolyte on their first day in the sanctuary, this was the very stone that Rhea had wrapped in swaddling clothes and handed to Kronos to swallow, saving the infant Zeus. Later, Zeus had released two eagles from the opposite ends of the cosmos; they had flown across the heavens and met precisely at this spot, marking it forever as the center of creation.

It sat quietly on its low bronze plinth, gleaming in the morning sun. Yet as Callista approached it, her bare feet slanting carefully over the marble flags, she felt a strange, cold vibration radiating from the stone—a low, rhythmic thrumming that had nothing to do with the wind or the footsteps of the gathering crowds.

A dozen men were standing around the perimeter of the courtyard, surrounded by their retinue of guards and scribes. Among them stood Archon Callimachus of Athens, a man whose dark beard was neatly trimmed in the austere style of his city, wearing a mantle of rich Tyrian purple that dragged slightly on the stone.

"High Priest," Callimachus said as Nicander led Callista forward. The archon’s voice was clipped and efficient, the voice of a man who spent his days negotiating grain contracts and naval budgets in the Agora. "We have been waiting since the third hour. The reports from the coast are troubling. Three of our patrol vessels were driven ashore near Itea by a sudden, violent surge—without a cloud in the sky. The sailors claim the sea rose up like a wall and swallowed the piers."

"The sea god has many moods, noble Callimachus," Nicander said smoothly, bowing his head with practiced reverence. "Poseidon often demands his due before the spring trading begins."

"It was not Poseidon," Callimachus said, his dark eyes shifting from Nicander to Callista. He studied her thin face, her wet hair pinned tightly beneath the sacred wool band, and the slight tremor in her hands. "The water tasted of sulfur. And the earth beneath the lower market quivered like a dying horse. The elders in Athens wish to know if the sanctuary has seen the meaning of these signs."

Nicander stepped forward, placing a reassuring hand on the edge of the bronze plinth near the Omphalos. "The Pythia has just emerged from the adyton. The god has spoken."

Callista felt every eye in the courtyard lock onto her. Timon stood near the outer colonnade, holding a silver ewer, his jaw clenched tight.

"And?" Callimachus pressed, taking a step toward her. "What is the word of Apollo for the city of the owl?"

Callista looked down at the Omphalos Stone.

The carved stone netting seemed to pulse beneath her gaze. In the high, brilliant sunlight, she saw something that the priests and archons apparently could not: thin, hairline fractures crisscrossing the ancient marble beneath the carved wool pattern. They were fine as spiderwebs, radiating outward from the rounded peak of the stone toward its base. And from within those micro-cracks, a faint, wispy breath of sweet, rotten vapor was slowly escaping, dissolving into the clean mountain air.

Find the eye beneath the eagle's foot, the voice from her vision whispered back into her mind, clear as a silver bell struck in an empty room.

She took a slow, deliberate breath, avoiding the direct vapor rising from the stone.

"The god commands vigilance," Callista said. Her voice was quiet, but the acoustics of the marble courtyard carried it clearly to every ear.

Nicander shot her a sharp, warning glance, his knuckles turning white where he held his robe.

"Vigilance against whom?" Callimachus asked, frowning. "The Persians? The Spartans? The hill tribes of Locris?"

"Vigilance against the foundation," Callista replied, stepping closer to the stone, her eyes fixed on its base. "The god says that when the sea turns to sulfur and the mountain hums, men should look not to their shields, but to their anchors. The city that trusts only its walls will find them turned to dust."

A low murmur rippled through the Athenian delegation. One of the older diplomats shifted uncomfortably, pulling his cloak tighter around his chest.

"That is... remarkably specific for a Pythian response," Callimachus noted, his brow furrowing deeper. "Usually we are told to build wooden walls or wait for the fifth moon."

"The times are not usual, archon," Nicander interrupted quickly, stepping between Callimachus and Callista with a wide, radiant smile. "The god sees the pride of men and reminds them that even the high crags belong to the immortals. The message is clear: Athens must offer libations at the harbor, reinforce her sea walls, and ensure her hearths remain pure. A standard, yet urgent, divine admonition."

"And the sulfur?" Callimachus insisted, looking over Nicander’s shoulder at Callista. "What of the sea rising without wind?"

"A cleansing," Callista said, before Nicander could speak for her. "The earth is washing its face. If you do not clear the rot from your markets, the water will do it for you."

Nicander’s hand settled firmly on Callista’s shoulder, his fingers digging into her flesh through the wool chiton with painful force. "The Pythia is weary from her communion," he announced loudly to the assembled men. "The pneuma takes a heavy toll upon the body. She must return to the sacred quarters to rest and pray."

He did not give Callimachus a chance to reply. With a firm, unyielding tug, he turned Callista around and guided her toward the private archway that led to the priests' residence.

As they crossed the threshold into the deep shadow of the interior passage, away from the light of the courtyard, Callista looked back over her shoulder one last time.

The Omphalos Stone stood in the center of the sunlit pavement. A single, dark crow fluttered down from the temple roof, landing heavily on the stone’s rounded crest. It tilted its head, fixed its black, bead-like eye on Callista, and gave a harsh, raspy croak that sounded remarkably like a laugh.

The priestess's quarters were tucked into the northern flank of the temple complex, carved directly into the living rock of Parnassus where the cliff rose sheer and black toward the sky. It was a cold, quiet room, furnished only with a narrow wooden frame bed strung with leather thongs, a single pine chest, and a low bronze lamp that flickered in the draft from the narrow, high window.

Callista sat on the edge of the coarse wool blanket, staring at her bare feet. The stone floor felt icy, but she welcomed the cold; it seemed to anchor her to the solid world, keeping the lingering, weightless sensation of the adyton's vapors at bay.

The door latch clicked, and Timon slipped into the room, carrying a wooden tray with a small bowl of steamed barley, three dried figs, and a cup of cold spring water. He set the tray on the pine chest and pulled up a low stool, sitting down with a heavy sigh.

"Nicander is furious," Timon said softly, looking toward the heavy oak door. "He's in the treasury with the archons now, trying to smooth things over. He had to promise them a dedicated bronze statue of Athena to offset your comment about the rot in their markets."

"I didn't choose those words, Timon," she said quietly. "They were placed in my mouth."

"I know," he said. He reached out and touched the small bronze ewer he had brought, his fingers tracing the handle. "I was standing near the doorway when the floor shook. It wasn't like a normal quake, Callista. It didn't rumble sideways like the ones we get in the autumn. It felt like... like something large was hitting the bottom of the rock from below. Like a fist trying to punch its way out."

Callista looked up at him. "You felt it too?"

"Everyone in the courtyard felt it, though the priests are pretending it was just a draft blowing through the lower vaults," Timon said. He lowered his voice even further, leaning closer. "After Nicander dragged you away, I went back to clear the censer near the Omphalos. Callista... there was oil leaking from the base of the stone."

"Oil?"

"Black oil. Thick and smelling like rotten pitch," Timon whispered. "I wiped it up with a rag before any of the Athenians saw it, but the stone was warm. Not sun-warm. It felt like a fresh loaf of bread taken straight from the oven."

Callista closed her eyes, remembering the vision of the serpent coiling around the sun, the dark, suffocating wave of mud and crushed stone burying the white roofs of Delphi.

"The stone is cracking," she said. "I saw the lines in the marble. Fine as hair, but they are there."

"The Omphalos can't crack," Timon said, a note of stubborn skepticism creeping into his tone. "It's solid marble. It was set there by the gods before our grandfathers' grandfathers were born. It has stood through wars, fires, and winter snows."

"Everything cracks if you strike it hard enough," Callista replied. She leaned forward, resting her elbows on her knees. "The riddle... the voice said: Find the eye beneath the eagle's foot, or let the stone return to dust. What does that mean, Timon?"

Timon rubbed his chin, thinking. "The eagle's foot? There are dozens of eagle statues in the sanctuary. The bronze one given by the Spartans after the sea battle at Samos has an eagle holding a snake in its talons. And the marble stele near the Athenian treasury has two eagles carved into the crest."

"No," Callista said, shaking her head. "It wasn't a statue. It felt older than that. Something buried."

"Buried?" Timon frowned. "The whole mountain is full of old walls and foundations. Before the temple was built three hundred years ago, there was an older shrine down by the Castalian spring. The old women used to say it was dedicated to Gaia, back when the earth spoke without needing a priest to write down the rhymes."

A sudden, sharp knock at the door made them both jump.

The oak door swung open, and Nicander stepped into the small room. He looked tired; the carefully arranged curls of his beard seemed slightly disheveled, and the sharp, confident line of his shoulders had sagged. He carried a heavy leather scroll case under his arm.

"Leave us, Timon," the High Priest commanded softly.

Timon hesitated for a fraction of a second, glancing at Callista, before bowing his head and hurrying out into the corridor, pulling the door shut behind him.

Nicander walked over to the narrow window, looking out through the slit of stone at the gray cliffs rising above them. He stood in silence for a long moment, the wind whistling faintly through the aperture.

"The Athenian archon gave us fifty silver tetradrachms," Nicander said finally, his voice lacking its usual theatrical resonance. "He was pleased enough with the answer, even if it was grim. Athens loves a warning; it gives them an excuse to build more ships and tax their neighbors."

"You don't believe my vision was just the laurel, do you?" Callista asked quietly from the bed.

Nicander did not turn around. He reached into his robes and pulled out a small piece of parchment, folded tightly and sealed with green wax.

"Twenty years ago," Nicander said softly, "when I was still a junior priest serving under Old Theano, a messenger arrived from the north. He didn't come to the adyton. He didn't pay the tithe or offer a heifer at the bronze altar. He was a wild-eyed man from the mountains of Thrace, wearing skins and smelling of bear grease."

He turned to face her, his graying eyebrows drawn together in a deep furrow.

"He brought a message from an old shrine in the north—a place where men pray to the ancient spirits of the forest before Apollo ever set foot on Parnassus. He said that every six hundred years, the earth demands a accounting. He said the Python was not killed by Apollo's golden arrows; it was only pinned to the deep rock beneath the Omphalos, held down by the weight of the god's home."

Callista sat up straighter, her pulse hammering against her ribs. "And what happens when the six hundred years are up?"

"The pin slips," Nicander said flatly. "The creature turns in its sleep, trying to shake off the stone. And if the vessel sitting on the tripod cannot hold the light, the mountain opens its throat."

He held out the folded parchment toward her.

"What is this?" Callista asked, taking the heavy paper. The green wax seal was impressed with the mark of an ancient, crude knot—not the sleek lyre of Apollo or the owl of Athens.

"The map of the lower foundation," Nicander said. "Below the adyton, deep within the rock where even the Hosioi are forbidden to go, there is a door. It was sealed with lead during the reign of the first kings. Behind it lies the original sanctuary—the place where the earth-mother was worshiped before the sun god claimed the crags."

"Why are you giving this to me?" she asked, looking up from the seal into his cold, gray eyes.

"Because the Omphalos is warm, Callista," Nicander whispered, his aristocratic mask dropping completely to reveal the terrified, desperate man beneath. "I felt it when I touched the stone today. It was hot as a branding iron. And the water in the sacred spring turned bitter an hour ago."

He stepped back toward the door, his hand resting on the heavy iron ring of the latch.

"The archons think we hold the keys to the future," Nicander said bitterly. "They think we sit up here on our high mountain and read the minds of the gods like lines in a book. But we are just men standing on a thin sheet of ice over a very deep pond. If the ice breaks, Callista, all the gold in the treasuries won't buy us a second breath."

"What do you want me to do?" she asked.

"Read the scroll," Nicander said. "Look for the eye. And pray to whatever god you trust that the thread holds until the morning."

He pulled the door open, stepped out into the dark, echoing corridor, and closed it behind him, leaving Callista alone in the dim room with the sealed parchment and the low, persistent hum of the mountain deep beneath her feet.
