Chapter 64 The Hidden Heir
(Caelum Ashborne)
The first blast of fire ripped him out of sleep.
Not Hellfire. Not the slow, suffocating burn that seeped from the palace walls. This was sharp—clean—a knife of gold heat driving straight through his chest. It cut through the heavy, sulphurous air of his alcove like winter lightning, shockingly pure against the constant oppressive warmth of Hell.
Caelum jolted upright in the narrow shadow Alcove Apollo allowed him. His breath tore in, too fast, lungs seizing like he’d been pulled from drowning. Shadows recoiled from his skin in a frantic flutter, then pressed in again, clinging, trying to smother the alien light humming under his ribs.
The mark on his forearm burned.
He shoved his sleeve up with shaking fingers.
The ember-sigil—dormant for years, quiet beneath the layers of shadow and demon magic Apollo had wrapped him in—glowed furious gold beneath his skin. Lines of molten light crawled along the old pattern, threading and re-threading the symbol he’d been born with: the crest of Ashborne, the promise of Emberborn. The edges of the sigil seemed to lift from his flesh, like a brand remembering the moment it first kissed skin.
“Shit,” he breathed, voice ragged.
The palace around him continued its usual restless groan—stone shifting, distant screams, the low thunder of Hell’s pulse—but over it, humming through it, was something new.
Her.
Caelum squeezed his eyes shut, letting the magic wash over him. The first wave nearly doubled him—hot and wild and untrained, like a firestorm lit under wet wood. It crackled across his senses, too bright, too loud, full of jagged edges and accidental flares. Fear tangled in it. Pain. A stubborn refusal to break. It felt like someone had set a torch to the bones of the realm and then handed him the handle.
He saw flashes— not images, not really, but impressions:
Fur tangled around pale limbs. A mark burning on a throat. A girl’s heart beating like a drum of war, not surrender. The Heir. Awake. In his palace.
“Of course,” he muttered. “Of course he would find her.”
The mark on his arm seared hotter in answer, as if offended by his tone.
He swung his legs off the low shadow-slab that passed for a bed and stood, bare feet meeting cold black stone. The shadows under him shifted, gathering instinctively, ready to carry him into the walls, into the ceilings, anywhere he needed to go. Anywhere Apollo ordered him to go.
Except back across the veil.
He flexed his left hand. The leash mark that bound him to the Devil—ink-black, clawed through with faint glints of gold—coiled faintly on the back of his palm, answering the same signal with a very different hunger. It prickled like frostbite made of smoke, a possessive ache that pulsed in time with the deeper thrum of the palace itself.
Two marks. Two masters. Two flames tugging at the same tether.
Perfect.
The second wave hit a heartbeat later. This one was stronger, sharper, threaded with something that felt like a scream turned inside out. Caelum sucked in a breath between his teeth. The ember-mark on his arm flared, the light punching through skin and shadow both. For one brief moment, it outshone the darkness Apollo had coated him with.
He didn’t have time to swear before the world tilted. The air in front of him thickened, heat condensing into a point just above his outstretched hand. Embers rose from the cracks in the floor, swirling together in a tight spiral. Shadows tried to interfere, but the fire burned through them, uncaring.
“Not here,” he hissed. “Not—”
Too late.
The embers flared, fusing into a single burning brand of light. A voice rolled through the tiny space, deep and rough and carved from smoke and stone.
“Caelum.”
His throat clenched.
“Father,” he answered quietly.
The ember-flame stretched, sharpening into a rough outline of a man’s face—no clear features, just the impression of strong bone and old scars. Eyes like coals. A crown of shadowed horns made of smoke and memory. Heat radiated off the projection with such intensity that the nearby shadows hissed and shrank back, leaving Caelum momentarily exposed.
Arkael Ashborne. Leader of the Emberborn. The man who had taught Caelum to walk on hot stone before he could walk on grass.
“You felt it,” Arkael said. Not a question.
Caelum swallowed. “You sent it hard enough. The entire palace felt it.”
“Not my doing,” his father said. “Hers.”
Her flame, then. Unshaped and wild, reaching for its kin without meaning to.
Caelum forced his voice steady. “She’s in the palace.”
“I know.” There was a thread of hate in Arkael’s tone that could have melted metal. “The surge came from the Devil’s direction. Did you think I would not feel where our Heir was caged?”
Heir. Caelum’s jaw tightened. He’d grown up on that word, half rallying cry, half lullaby. When the Heir rises, we rise. When he was younger, he’d believed it would be simple. The Heir would appear, they would kneel, they would burn the world.
Then he met Apollo. And learned that the ashes of one war did not care much for the prophecies of the next. Prophecy did not account for leash marks and shadow collars and the way demons smiled while tightening them.
“What do you want from me?” he asked.
“Report,” Arkael ordered.
Of course.
“Hell is as charming as ever,” Caelum said dryly, leaning back against the cold wall. The shadows licked along his spine, resenting the flame-light hanging between them. “The king spends most of his time pretending he’s not unravelling. The wards hum like they’re waiting for something. The court is restless but obedient. The human is… inconvenient.”
The flame flared. “Inconvenient?”
Caelum’s mouth curved faintly. “He’s not himself around her. You knew that already. You felt it the night he dragged her through the veil.”
He remembered that night clearly. The palace had gone quieter than he’d ever heard it, as though the stone itself had been holding its breath. Apollo had come back bleeding and human, carrying a limp girl wrapped in mud and blood and stubbornness.
Caelum hadn’t known who she was then. Not fully. He’d known enough to feel the shift. The shadows had recoiled from her like they’d met sunlight; the wards had flared once, bewildered, then settled around her as if unsure whether to cage or crown.
“And now?” Arkael asked.
Caelum hesitated. The ember-mark on his arm pulsed in time with a distant heartbeat—hers, if he had to guess. Or maybe his own. Hard to tell where one ended and the other began when rage and destiny intertwined.
“Now she’s… louder,” he admitted. “Her presence. Her magic. It’s like someone turned the volume up on every flame in the palace. The wards keep flaring. His shadows keep twitching. He’s… drawn. Obsessively so.”
“And you?” Arkael asked.
Caelum’s fingers curled slowly.
He had seen her. Up close. In hallways, in stolen glances, through the gaps in doors when he shouldn’t have been looking. Too human, too breakable, too brave. She met Apollo’s gaze like she had a death wish and a secret desire to see if she could cut God’s throat herself.
He understood that impulse.
“I am doing what you asked,” he said. “Playing the obedient shadow hound. Fetching the Devil’s orders. Fetching his girl. Watching.”
“And feeling,” Arkael added sharply.
Caelum stiffened.
