The sister's breath plumed white in the chill vault air, her palm pressed flat against the rough granite. The locket, a small silver circle, remained gripped in her other hand. She fixated on Anatta—not the lines of Phaeron’s countenance, but the memory of the cold, dead fury that had twisted it moments before. “The malice… it deepens its hold,” Anatta said, his voice a low rasp, still feeling the phantom claw marks of Phaeron’s rage within. “Your brother’s spirit is a tempest, caught between life and oblivion. Every revelation, every memory of his suffering, strengthens its fury.” She pushed away from the wall, straightening her spine. “Then we quiet the storm. Tell me what must be done. You said Phaeron attempted a rite to repair the Blade. What manner of working demands such intensity?” Anatta led her to a dusty alcove, pulling out a faded scroll depicting intricate spiritual diagrams. “The Sundering, as you know, harnesses immense Aura flow to reshape reality. Phaeron’s initial working sought to mend the Blade of Echoes by feeding it the rebound Aura from our duel, a catastrophic miscalculation. The Blade absorbed it all, overloading and taking both our lives. To contain such an uncontrolled surge… one would need a stabilizing anchor, a counter-resonance.” He unrolled another, smaller parchment, its edges brittle with age. “We must construct a Soul-Calming Array. It won’t nullify the echo, but it can dampen its violent surges, give us more time. The technique is ancient, requiring specific geomantic alignments and a conduit of pure, unblemished Aura.” “A conduit?” Her brow furrowed. “The Spire’s Aura is too dense, too wild to shape with precision.” Anatta reached into his tunic and produced the small, unadorned Aura-bearing rock he had found in Phaeron’s hidden compartment. Its surface was smooth, faintly luminous, radiating a steady, calming pulse. “This. It is not merely a pure source. Observe closely.” He extended it to her. She tilted the stone, squinting as she traced the surface. “It feels polished clean. No veins, no impurities. Yet there is a strange shimmer here, near the base.” She pointed to a minuscule imperfection, barely visible to the naked eye, a hairline indentation that caught the light oddly. “Most would dismiss it as a trivial flaw in formation,” Anatta murmured, taking the stone back. He turned it, catching the dim lamplight just so. “But it is not a flaw. It is an intentional inscription, microscopic and impossibly precise. Phaeron etched a minute resonance array directly into the mineral matrix.” He moved closer to the flickering oil lamp, angling the mineral. “Look closely. The lines are faint, yet they form an unbroken diagram. It absorbs spiritual resonance—specifically, the chaotic backlash of an overloaded Sundering.” Phaeron wasn’t just trying to fix the Blade. He was building this as a failsafe, a desperate measure to contain the very forces he knew he was about to unleash, should his attempt to mend the artifact go awry.” Her fingers pressed to her lips. “He anticipated this? That he might fail, that the Blade could unleash such ruin?” Her tone thinned with sudden quiet. “He prepared for the worst,” Anatta confirmed, his gaze distant. “He understood the immense risk. This stone was meant to prevent the entire Spire from being engulfed by spiritual chaos. He was trying to protect you all.” The silence that followed stretched long across the granite floor. Her knuckles loosened around the silver locket. “Then this… this is the anchor. If we can activate it, perhaps we can bring peace to his lingering spirit.” Anatta nodded, a slow, deliberate movement. “Precisely. We will use the geomantic nodes Phaeron detailed in his research. The array will draw upon the ambient Aura of the vault, refine it, and channel it through this anchor. It will create a localized field that will soothe the tormented echo, allowing me to delve deeper into his memories without being overwhelmed.” “And the elder cousin's coup?” she asked, her shoulders squaring. “The traitor plans to use the unstable Blade of Echoes. How will this Soul-Calming Array help with that?” “If the usurper activates the Blade, the uncontrolled Aura will run rampant,” Anatta explained, tracing the faint lines on the crystalline core. “This array, once charged, will draw off that energy, pulling it away from the spire's living quarters. It will not break his hold, but it buys time, turning the recoil against him.” They worked through the fading light of afternoon, Anatta offering quiet instruction while she aligned mineral points along the vault floor. The faint glow from the focus pulsed at the heart of their nascent array, casting steady rings across the flagstones. As dusk painted the high, narrow windows of the Spire in shades of violet and grey, a low rumble started deep beneath them. It was a faint tremor at first, a vibration that hummed through the soles of their feet, then grew, a guttural groan that vibrated through the very stones of the vault. Dust sifted from the ceiling. The oil lamps swayed violently, casting erratic, dancing shadows across the ancient walls. “What was that?” she cried, stepping back from the circle. Anatta’s face tightened. “Too soon. It’s too soon.” The tremor intensified, shaking the entire Obsidian Spire with a force that sent smaller stones clattering from the shelves. A deafening crack echoed from somewhere above, followed by the sound of rending metal. Suddenly, the heavy door to the Vault of Whispers burst open with a resounding bang. A junior servant, his face ashen, stumbled into the room, his uniform disheveled, hair plastered to his forehead with sweat. His eyes were wide with terror, fixed not on them, but on some unseen horror above. “Lord Phaeron! My Lady!” he shrieked, voice cracking above the groaning masonry. “The high heir! He unsealed the Blade of Echoes! A storm of raw Aura tears through the Spire’s peak!”
