The salt spray off the southern cliffs tasted of old copper and dead kelp.
Beneath the shadow of the Obsidian Enclave, the ocean did not roll in clean breakers; it choked against a maze of jagged sea-stacks known as the Drowned Teeth. These towering pillars of black basalt jutted from the foam like rusted spears, wrapped in thick ropes of dead bladderwrack and encrusted with pale, razor-sharp barnacles that wept clear, caustic brine.
Far above, cloaked within the low-hanging thunderclouds, Cinder circled in wide, patient rings. The volcanic drake flew without a sound, his sixty-foot obsidian wings banking on the rising sea-drafts, his belly a faint, sullen coal of heat hidden against the storm.
Down on the water, the four Sun Wyrms floated in the shadow of a hollow sea-arch, half a league outside the range of the fortress's heavy iron cliff-batteries.
Lyra knelt on the slick, leather-clad back of the elder wyrm, washing the dried salt and blood from her face with water from a leather skin. The cold mountain spring water cleared the lingering sting from her nostrils, but the deep, bone-deep ache in her core remained. Re-weaving the ruptured Weave-Aura had strained her channels, leaving her inner fire banked low, like a hearth smothered beneath damp moss.
Gideon stood braced against the wyrm's saddle-arch, his massive arms crossed over his chest, his wolf-pelt mantle damp with sea-mist. His amber eyes were fixed on the mouth of the fortress harbor, tracing the movement of the heavy iron-shod galleys patrolling the entrance.
"Three galleys at the chain-boom," Gideon said, his low baritone cutting through the crash of the surf against the basalt. "Double-banked with southern conscripts. Star-iron ballistas mounted on the forecastles, trained downward into the harbor shelf."
"They aren't guarding against an invasion fleet," Commander Varis said, adjusting the straps of her scale hauberk as she stepped to the edge of her mount's shoulder. "They're guarding the floor. Kenneth knows the northern anchors are broken. He knows we came by water."
Talia leaned forward, spitting into the dark sea. "Let them watch the water. We bring Cinder down through the cloud-deck, burn the galleys to their waterlines, and drop onto the battlements."
"No," Lyra said, rising to her feet.
She moved with steady grace, though Gideon's hand instantly settled on her hip, his thumb hooking into the belt of her brigandine with that unyielding, protective weight she had come to rely on. She leaned slightly against his solid thigh, drawing on the quiet, unshakeable heat radiating from his frame.
"If Cinder breathes within two leagues of that harbor, he ignites the brine-mist," Lyra explained, pointing toward the oily sheen coating the surface of the water between the sea-stacks. "Kenneth didn't just fortify the cliffs. He’s saturated the bay with distilled Abyssal pitch. One spark from above, and the entire harbor becomes a fire-storm. We'd incinerate the three thousand slaves chained to the lower oar-banks in the fortress grottos before we ever touched the anchor."
Gideon’s jaw hardened, his teeth grinding with a low, dangerous sound. "The coward hides behind his thralls."
"He hides behind the Third Pillar," Lyra replied, turning her gaze toward the lightless depths directly beneath the fortress promontory.
Even from here, half a league distant, her Weave-sense could feel the sickening, heavy cadence of the anchor.
It was different from the first two. It did not hum with acoustic vibration, nor did it pulse with raw, necrotic blood-magic. It sat on the sea floor like an open wound—a massive, sunken forge of black core-iron, continuously drinking the natural heat from the water and transmuting it into lightless, freezing pressure.
"The Drowned Forge," Lyra murmured, her hazel-grey eye narrowing while her violet eye flickered with sharp, celestial analysis. "It's an elemental inversion engine. It consumes fire to generate ice. The closer our flames get to that anchor, the colder the water becomes. If we dive in with open starlight, the forge will turn our own magic into a solid tomb of mineral ice."
"Then how do we break it?" Talia asked, her brow furrowed. "You can't strike it with steel from the surface, and we can't burn it without freezing ourselves to death."
Gideon looked down at Lyra, a dark, predatory understanding passing between their eyes.
"We don't burn it from the outside," Gideon rumbled, his deep voice dropping into that quiet, terrifying timber that preceded a slaughter. "We drown the fire in its throat until it chokes."
Lyra’s lips parted in a breathless, dangerous realization. "The Drake core."
"My bloodline didn't inherit the sun from the sky, little bird," Gideon said, his fingers tightening against her hip, pulling her flush against his ribs. His scarred face bent close to hers, his breath hot against her temple. "The first Drake pulled his ember out of the deep earth beneath the mountains. The magma that sleeps beneath the ocean floor doesn't ask permission from the water to burn. It boils the sea until the rocks crack."
He looked toward Varis and Talia.
"Varis, take the three young wyrms and the Void-dancers," Gideon commanded. "Skirt the outer shoals. When the water begins to churn white, strike the harbor chain-boom from below. Sever the mooring lines of those galleys and drag them away from the grotto mouths so the slaves don't drown in the backwash."
"And you?" Varis asked, her expression tight with grim loyalty.
"Lyra and I are going into the forge," Gideon answered.
He unclasped his wolf-pelt mantle, letting the heavy, sodden fur drop to the wyrm's leather saddle. Beneath it, his broad shoulders and scarred chest were laced with the silver-red lines of their true-mate covenant—runes of ancient fire that pulsed in synchrony with the beating of Lyra's heart.
He drew his primary star-iron claymore, rolling his shoulders until the heavy muscles along his spine locked into place.
"No Weave-Aura this time, Lyra," Gideon growled softly, his amber eyes burning with unbridled, feral heat. "No protective skin to draw the forge's siphon. We dive on raw blood. You hold our breath in your lungs, and I'll be the furnace that keeps the marrow in your bones from freezing."
Lyra reached up, her small hands clamping onto the thick muscles of his neck, pulling him down until their foreheads rested together.
The silver-red cord between their chests flared—not with bright, fragile light, but with a deep, subterranean crimson that smelled of wild mountain cedar, burning iron, and the molten heart of the world.
"I won't let you drown, Gideon," she whispered, her gaze locking onto his with absolute, sovereign certainty.
"I know you won't, Queen of mine," Gideon rumbled against her mouth, his fangs grazing her lower lip in a fierce, possessive claim. "Now let's go show High Alpha Kenneth what happens when you try to put out a volcano with a bucket of salt."
Together, without a drop of shielding magic, the King and Queen of the North dove headlong into the black, freezing waters of the Drowned Teeth.
