The masonry groaned, a deep, grinding shudder that vibrated through the Calmecac barracks. Dust, fine as ground chalk, sifted from the ceiling cracks, drifting over the sleeping mats and the carved glyphs on the walls. Tlanextli, still clutching the blood-stained handkerchief, sat bolt upright. His star-demon senses, usually a dull thrum beneath his skin, flared with a frantic, warning tremor. Then came the crash. Not a single impact, but a series of rhythmic, heavy thuds, like giants striking solid rock. A guttural roar, metallic and chilling, echoed from the main hall. “Intruders!” a cadet’s panicked cry ripped through the night. Xilotsa burst into the boys’ sleeping quarters, her movements sharp and economical, a sleeping tunic hastily pulled over her undergarments. Miztli, a blur of pitch-dark plumage, zipped around her head, chittering indignantly. “Everyone up! To the courtyards! Quetzalli, rally the others!” Quetzalli, already half-dressed, her sun-amulet gleaming at her throat, moved with the swift grace of a hummingbird. “To the training grounds, Xilotsa! It’s the safest path!” Before they reached the doorway, the heavy cedar planks exploded inward under sheer force. Splintered laths whistled through the air. A hulking construct, forged from jagged, volcanic glass, filled the gap, its head a featureless, snarling maw of dark basalt. Its arms, thick as tree trunks, ended in bladed mauls dripping an oily black fluid. Two more stone automatons lumbered in behind it, gouging trenches across the clay floor tiles. “The Chalchiutl quarters,” a sneering voice drawled from behind the automatons. Lord Yaotl, Xilotsa’s uncle, emerged from the shadows, his face a predatory mask of cruel amusement. His robes, embroidered with the motif of a devouring serpent, billowed around him. “Such a pathetic little nest. And look, the little star-demon has found himself a new protector.” His flint-dark eyes fixed on Tlanextli, then slid toward Xilotsa with venomous focus. “Yaotl,” Xilotsa’s voice was a low growl, her hand instinctively going to the small, concealed dagger at her waist. “You dare breach the Calmecac?” “I dare reclaim what is mine. The star-demon’s blood belongs to the House of Xocoyotl, not to some disgraced noblewoman playing at mother.” He gestured with a flick of his wrist. “Bring him.” The lead construct surged forward, its bladed fist swinging in a wide arc toward Tlanextli. The boy, frozen for a split second by the sheer size of the creature, would have been crushed. But Xilotsa moved faster. She shoved Tlanextli behind her, drawing her dagger, a glint of polished jade. It was a futile weapon against solid stone. Just as the bladed fist descended, Tlanextli’s eyes flared a terrifying, incandescent violet. A low, guttural shriek tore from his throat – not of fear, but of pure, unadulterated fury. His small, boyish hands, suddenly imbued with an unnatural strength, shot out. He didn’t try to block the fist. He plunged his fingers, claws sharp as volcanic glass knives, into the automaton's shoulder, directly into a glowing seam where runic magic held its joint together. The construct screeched, a dry shriek of grinding rock. Its limb sheared along the rune line, disintegrating into a cascade of sharp grit across the flagstones. Destabilized, the thing staggered back, neck joints popping as it pivoted toward the boy. “Impossible!” Yaotl roared, his composure cracking. “He shouldn’t have that much control!” Tlanextli, still radiating that vibrant violet energy, lunged again. He moved with a feral grace, not the trained movements of a knight, but the desperate, instinctual savagery of something wild and cornered. He tore at the construct's chest, ripping through magically bound vitreous plates until the core—a pulsing dark crystal—cracked free. He snatched the node, snapping it between his fingers, and the machine collapsed into an inert pile of gravel. “Tlanextli!” Xilotsa’s voice was sharp, a mix of awe and alarm. His power was raw, terrifying, and completely out of control. It was not the gentle power she imagined for her quiet retirement. This was the power of a weapon, a predator. One of the remaining sentinels, reacting to the destruction of its twin, wheeled toward Xilotsa. She watched the violet smoke coil off his knuckles, calculating his exposure rather than her own safety. Her body, still weak from its underlying sickness, gave a violent cough, a spray of dark blood blossoming on the dusty floor. “Xilotsa! Hold still!” Quetzalli cried, her hands glowing with soft, golden light, ready to cast a healing spell. But Xilotsa shook her head, a stubborn, frantic refusal. She couldn’t let Quetzalli see the darkness within her, couldn’t let her know the truth of her dying body. It would ruin everything, her carefully constructed plan for a quiet end. Instead, Xilotsa scanned the cracked rafters overhead. The stone archway, supporting the upper floor balcony, was directly above the charging golem. Stress fissures webbed outward from the lintel, lime powder trickling onto the flagstones. With a furious yell, she didn’t meet the golem’s charge. She veered, sprinting towards a support pillar, slamming her foot against a loose stone block near its base. The already unstable archway shuddered violently, then began to splinter with an agonizing creak. The stone sentinels, driven purely by the blood-sigil command, continued their plodding advance. “Get out!” Xilotsa screamed at Quetzalli and the other cadets, pushing Tlanextli towards the gaping hole in the wall. He hesitated, his violet eyes fixed on her, but Miztli, screeching, tugged at his hair, pulling him through the opening. The last thing Xilotsa saw of his face was a look of pure, unbridled desperation, a stark realization of his own powerlessness. The archway gave way, bringing down half a ton of limestone across the entrance. The two remaining automatons, trapped beneath the cascade, broke apart instantly under the falling blocks, their vitreous shells smashed to powder. The floor trembled, and a cloud of debris filled the room, obscuring everything. Yaotl, his face contorted in a sneer that was more feral than human, stalked through the settling dust. He found Xilotsa leaning against a remaining wall, her breath coming in ragged gasps, her hand pressed to her chest. The small jade dagger was still clutched in her hand, useless. “Clever, Xilotsa. Almost as clever as your ancestor, the Shadow Empress.” He stepped closer, his voice dropping to a dangerous whisper. “But you forget, I know your family’s deepest secrets. I know the blight that afflicts your bloodline.” His black pupils shrank. “I know the black rot that festers within you, the one you hide behind that fierce pragmatism. The Emperor, you know, has a keen interest in… *rotting souls*.” He stepped within striking distance, breathing cold bile against her cheek. “Unless you surrender the boy by the next eclipse, I will inform the Emperor that his esteemed General Xocoyotl has a daughter whose soul is already claimed by the underworld, and that she shelters a rogue star-demon.”
