The Observatory of High-Peak stood at the very edge of the world, a towering spire of frost-bitten white marble and wrought brass that pierced the perpetual twilight of Aethelgard. The wind here did not howl; it shrieked, a bitter, biting cold that sought to freeze the blood of any mortal foolish enough to brave the open balconies. Caelum, an apprentice Star-Tender of the lowest order, pulled his heavy, fur-lined cloak tighter around his thin shoulders. In his gloved hands, he held an Ignis-staff, its tip glowing with a trapped ember of primordial fire.
His duty was monotonous, unglamorous, and vital. He was tasked with reigniting the planetary braziers that kept the encroaching shadow-storms at bay. Above him, the true magic of the world burned. The stars of Aethelgard were massive, crystalline lanterns suspended in the ether, maintained by the elite High Astromancers. Caelum often stared up at them, tracing the constellation of the Aegis—the Great Shield—wishing he possessed the magical aptitude to fly among them.
It was during the third hour of his watch that the sky shattered.
Caelum was scraping rime off a brass dial when a sound like tearing silk echoed across the firmament. He looked up just in time to see the heart of the Aegis constellation flicker violently. The star, a brilliant sapphire beacon that had burned for ten millennia, suddenly went black. Then, it fell.
It did not fall like a meteor, burning with friction. It fell like a teardrop, dragging a streak of pure, weeping silver light behind it. The trajectory was unmistakable; it was plummeting toward the Whispering Tundra, just a few leagues north of the Observatory.
Protocol dictated that Caelum sound the great brass alarm bells and wait for the High Astromancers to assemble an expedition. But as he looked at the frozen wastes, he saw shadows detaching themselves from the tree line—Null-hounds, beasts born of the void, sprinting toward the impact site. The star would be devoured before the masters even finished putting on their robes.
Driven by an impulse he could not entirely explain, Caelum grabbed his Ignis-staff, secured his climbing harness, and threw himself over the balcony railing. He engaged the gravitational runes on his boots, sliding down the massive, icy cables that anchored the observatory to the mountain. He hit the snow-covered tundra running.
The impact site was a crater of melted snow and scorched earth. As Caelum approached, his breath caught in his throat. Lying in the center of the crater was not a shattered crystal lantern, but a girl. She was ethereal, her skin glowing with a faint, fading sapphire luminescence. Her hair floated around her head as if submerged in water, resembling a miniature nebula of stardust. She was curled into a fetal position, shivering, her eyes closed.
“By the Weaver,” Caelum breathed, sliding down into the crater. He knelt beside her, pulling off his heavy fur cloak and wrapping it around her fragile shoulders. The moment the fur touched her, she gasped, her eyes snapping open. They were solid, glowing pools of starlight.
“The dark,” she whispered, her voice like the chiming of distant bells. “It is hungry.”
A low, guttural snarl answered her. Caelum spun around. Circling the rim of the crater were five Null-hounds. They were creatures of absolute absence, resembling emaciated wolves made of swirling, black smoke, their eyes burning with a hateful, crimson light.
Caelum stood up, placing himself between the celestial girl and the beasts. He was no warrior; he knew only the defensive forms of brazier-tending. But as the largest hound lunged, jaws snapping with enough force to crush bone, Caelum didn’t flinch. He swung his Ignis-staff in a wide, sweeping arc.
The trapped ember at the tip of the staff flared. A ribbon of golden fire lashed out, striking the hound mid-air. The beast shrieked as the fire incinerated its shadowy form, turning it to harmless gray ash.
But the remaining four attacked simultaneously. Caelum spun, thrusting the staff into the chest of the second hound, but the third clamped its freezing, ethereal jaws onto his left arm. Searing cold shot through his veins. Caelum screamed, dropping to one knee.
Suddenly, a blinding flash of sapphire light erupted from behind him. The girl had risen to her feet, her hand outstretched. A shockwave of pure starlight blasted outward, completely vaporizing the remaining Null-hounds. The effort, however, was too much. The light in her eyes flickered, and she collapsed.
Caelum caught her before she hit the frozen dirt. His arm was numb, his heart racing, but he held her tight. “I’ve got you,” he whispered to the unconscious star. “I’ve got you.”
