The return to the Dragon Estate was marked by a silence so profound it felt heavy, a physical pressure that seemed to emanate from the very stone. As Astra's massive, steel-rimmed talons touched down on the familiar marble landing of the high stables, the servants didn't scurry forward with their usual practiced indifference. They froze. They felt the air drop ten degrees in a single breath, the moisture in the humid evening air crystallizing into a fine, glittering mist around the youngest heir.
Caelum dismounted, his movements no longer clumsy or weighted by the sluggishness of a hangover. He walked with a predatory grace, his boots clicking against the stone with a rhythmic finality. He didn't head for his room to hide. He headed for the Training Spire—the place where the "true" Dragons honed their fire, and the place he had been tacitly banned from for years.
He found her there, centered in the middle of a scorched obsidian floor.
Lyra Dragon. His twin sister. In their childhood, they had been inseparable, two halves of a whole. Lyra had loved him with a fierce, protective devotion, sharing her toys and her secrets. But as their mana awakened, the gap between them became a chasm. Lyra was a natural disaster in human form, commanding a flame so intense it turned the air into a shimmering haze of heat. Caelum was the "shitty" talent. To survive the social hierarchy of House Dragon, Lyra had made a cold, calculated choice: she had chosen to ignore him. She had watched him drown in wine and self-loathing, never offering a hand, fearing that his failure would stain her own meteoric rise. She loved him still, buried under layers of pride and duty, but she had treated him like a ghost for years.
Lyra was in the middle of a sequence, her movements a blur of high-speed strikes. With every punch, a gout of crimson fire erupted, melting the practice dummies of reinforced iron. She sensed him before she saw him. The heat of her aura flared instinctively, reacting to the sudden, intrusive chill that had entered the room.
She spun around, a sphere of roiling flame gathered in her palm. "Who is—?"
The words died in her throat. Her golden eyes—identical to their father's—widened as they landed on Caelum. But it wasn't the Caelum she remembered. The boy who had left was a trembling, pathetic mess of insecurity. The man standing before her was draped in rugged travel leathers, his skin pale as moonlight and his eyes reflecting a terrifying, crystalline depth.
"Caelum?" she breathed. For a second, the mask of the prodigy slipped, and the sister who used to hold his hand appeared. "You're back. Father said you had finally decided to rot in some mountain cave. I... I thought you weren't coming back."
Caelum didn't stop walking until he was ten paces from her. The clash of their auras was physical. Where her heat met his cold, a line of thick, white fog hissed into existence on the floor between them.
"The mountains were refreshing, Lyra," Caelum said. His voice was different—resonant, calm, and stripped of the jagged desperation that used to make him sound like a cornered animal. "They helped me clear my head. And my veins. It's amazing what you can find when you stop trying to stay warm."
Lyra's eyes narrowed, her protective instinct warring with her ingrained disdain. She was a combat prodigy; she could feel the sheer density of the mana radiating from him. It was impossible. A week ago, his mana circuits were a clogged drain. Now, they felt like a glacial river.
"What did you do?" she demanded, her voice rising to hide her confusion. "What forbidden artifact did you swallow? You know Father will kill you if you've tainted the bloodline with some black-market elixir. I won't be able to protect you if you've gone rogue, Caelum."
"You haven't protected me in years, Lyra. Don't start pretending now," Caelum replied, his gaze unwavering. "The bloodline was already stagnant. It needed to be frozen to be purified."
Lyra's pride flared. She couldn't accept it—the idea that her 'trash' twin had somehow closed a gap she had spent her life widening. She shifted into a combat stance, the crimson fire around her fists intensifying until it turned a violent, orange-white.
"I don't know what game you're playing, but a few tricks in the woods don't make you a Dragon," she hissed, though her heart pounded with a strange, forgotten fear. "Test your 'purified' blood against mine. Show me you're not just a corpse walking."
She didn't wait for an answer. Lyra lunged, her speed boosted by mana-bursts at her heels. She threw a straight punch aimed at his chest, a pillar of flame erupting from her knuckles intended to knock him back and remind him of the hierarchy she had upheld through her silence.
Caelum didn't dodge. He didn't even raise his arms. He simply exhaled.
A wave of absolute zero erupted from his lungs. The crimson pillar of fire didn't blow past him—it stopped mid-air. The orange-white flames turned grey, then translucent, then shattered into falling ice crystals before they could even touch his chest. Lyra's fist hit a wall of invisible, frozen pressure. The cold was so intense it bypassed her own fire resistance, numbing her arm to the shoulder in a heartbeat. She recoiled, gasping, her boots skidding on a floor that was suddenly coated in a layer of slick, black ice.
"Your fire is loud, sister," Caelum said, stepping forward. The white flame flickered to life in his palm—a silent, ghostly light that didn't cast shadows. "But it's weak. Heat is just movement. And I have learned how to make things... stay still."
Lyra looked at her hand. Frost was beginning to creep up her fingers, turning her skin a terrifying shade of blue. She tried to summon her fire again, but the mana in the air around her felt dead. Heavy. Unresponsive.
"You... you're not C-Rank," she whispered, her voice trembling. The sisterly love she had suppressed for so long surfaced as a sharp, stinging regret. She had ignored him for being weak, and now, in his strength, he looked at her like a stranger.
"I never was," Caelum said. He closed his hand, extinguishing the white flame, and the oppressive chill in the room lifted just enough for her to breathe. "Tell Father I'll be in the library. I have three months to prepare for the Academy, and I've wasted enough time being what you all expected me to be."
He turned his back on her—the ultimate insult to a Dragon—and walked out of the training spire.
Lyra stood alone in the center of the room, shivering. She looked at the iron practice dummies. They weren't just melted anymore. They were covered in a fine layer of white frost that refused to melt, even in the heat of the spire. She wanted to call out to him, to apologize for the years of silence, but the air he left behind was too cold to speak through. The "trash" heir hadn't just returned; he had brought a winter that her fire could no longer touch.
