The edge of the obsidian dagger was colder than winter ice, but the flesh of Malakor’s palm yielded without a tremor.
Aurelia drew the blade across his skin with deliberate care, watching the thick, sovereign crimson well up along the lifeline of his hand. It smelled of scorched bronze and dormant thunder—blood untainted by the rot of the lower valleys, rich with the ancestral fire of the high warlords.
Malakor did not look at the wound. His eyes remained locked upon hers, unblinking and dark, tracking every flutter of her lashes while the cavern around them groaned beneath another concussive blast from the siege engines above.
"Now yours," he said, his voice dropping into that low, command-laced timber that sent a shiver straight down the curve of her spine.
Aurelia turned the blade and drew the steel across her own palm. The stinging heat bloomed instantly, her blood answering with a faint, iridescent sheen—the silver luminescence of the Veil-touched lineage.
Before the first drop could hit the dust, Malakor closed his hand over hers.
Their fingers laced together, pressing wound to wound. The contact was an explosion of raw, suffocating sensation; his blood burned like molten lead against her veins, surging into her open skin while her own magic licked into his marrow like frostbite. A strangled gasp caught in her throat. She stumbled forward, but Malakor’s free arm locked around her waist, crushing her torso flush against his chest to hold her upright against the shockwave.
"Hold the thread, Aurelia," he rasped near her ear, his jaw clenched as the shared resonance flared white-hot through his own frame. His pulse hammered against hers in a savage, syncopated rhythm. "Do not let it drown you."
"I am holding it," she choked out, her head falling back against his shoulder as the crypt dissolved into blinding light.
Beneath their joined hands, the spilled blood did not drop—it rose.
Thin, luminous tendrils of crimson and quicksilver weaved through the air like silk spun by spiders, plunging into the jagged maw of the split dais. The weeping fissure shrieked. The violet mist that had been clawing its way toward the ceiling violently reversed direction, sucked back down into the subterranean abyss by the sudden, crushing weight of their united lineage.
The ancient wraiths beneath the flagstones wailed in fury as the metaphysical threshold snapped shut like iron jaws. The runes carved into the perimeter pillars flared once, violently bright, before burning out into dull, charred gray.
The deafening hum ceased.
Silence slammed down upon the sanctuary, broken only by the rattle of loose gravel and the ragged, shallow cadence of their breathing.
Aurelia slumped against him, her knees threatening to buckle as the magical expenditure drained the heat from her limbs. Malakor didn't let her fall. He shifted his grip, lifting her slightly until her weight rested securely against him, his face buried in the hollow of her neck where a sheen of cold sweat clung to her skin.
"The gate is sealed," she whispered, her forehead resting against the hard curve of his cheekbone.
"The gate, yes," Malakor breathed, slowly easing the pressure of their joined hands. The cut on his palm was already crusting black with clotted sovereign blood, while hers still wept pale crimson. He brought her wounded hand to his mouth, his lips pressing a searing, dark caress across the raw line of the cut, tasting the iron and magic that had bound them together.
The insolent tenderness of the gesture hit her harder than the ritual had. Her fingers curled weakly against his cheek, feeling the rough stubble and the cold grit of stone dust.
"Malakor..."
"Rest for ten breaths," he said quietly, his gaze lifting to meet hers with an intensity that promised no retreat, no surrender, and no mercy for the world beyond the vault doors. "Then we draw steel. The mountain pass belongs to us, and I intend to take their commander's head before dawn."
