The fortress didn’t rest after the first strike. We barely had time to breathe before the second wave hit. The Sealkeepers hadn’t even finished resetting the wards when the air shifted again—this time sharper, like the wind had been honed to a blade. The torches guttered and died in perfect unison. Darkness rolled in like a tide, swallowing the battlements, the halls, every corner of the keep. And inside that darkness… something moved. Kael’s voice was low beside me. “They’re inside the walls.” I tightened my grip on my blade. “Shadows can’t breach solid stone unless—” “Unless they’re not shadows anymore,” he finished grimly. The first one lunged from the dark so fast I didn’t see its face—just teeth. My wolf half reacted before I did. I slammed my blade up under its ribs, but instead of blood, there was only a burst of black smoke. It dissolved into the air, leaving a cold sting in my skin where it brushed me. Dozens more followed. The courtyard became a blur of movement—Sea
The fortress walls had stood for centuries. That night, they shook like they’d been built of sand. It started as a low hum beneath the stone, too deep for human ears but sharp enough to make the hairs on my arms rise. Kael and I had barely left the breach chamber when the hum spiked into a violent shudder. The sconces along the hall rattled in their brackets. Then—silence. Every warrior in sight froze. The air itself seemed to hold its breath. And then the mountain roared. Stone split somewhere in the depths below us. The floor buckled. A hot wind—wrong, not from any earthly direction—swept through the corridors, carrying the taste of iron and ash. Kael shoved me against the wall, his body between mine and the open hall. “Stay behind me.” “That’s not going to help if the mountain’s collapsing,” I said, gripping my own blade. “This isn’t a collapse,” he said grimly. “It’s Nytherion.” The name alone felt like a key turning in my ribs. I tried to shove the sensation down, but m
The fortress didn’t sleep that night. Not after what we’d just seen. Every corridor hummed with whispered urgency. Sealkeepers rotated in and out of the breach chamber in shifts shorter than an hour, afraid to leave it unattended for even a breath. Kael refused to let me out of arm’s reach, as if I might dissolve into stardust the second he blinked. I didn’t blame him. I’d barely made it out of that last encounter standing. And the whole time, I could feel Nytherion lurking at the edges of my mind—not speaking, not pressing, just… waiting. By the time the moon reached its zenith, I couldn’t stand the tension anymore. I slipped away from the makeshift war council in the upper hall and made my way toward the breach. Kael followed, of course. “You’re not going in there alone,” he said as I approached the warded arch. I met his gaze. “Then stay close. But if it talks to me—let me answer.” His jaw tightened, but he didn’t argue. Inside, the breach pulsed like a living wound. The
The fortress felt wrong. Not just tense—wrong, like the air had been swapped out for something that wasn’t made for breathing. It clung to my skin, heavy and charged, as if the stone itself was listening. The council hadn’t left the breach chamber since the incident. Kael hadn’t left my side since I collapsed. Neither had Cassian, though he masked it with restless pacing. Corren stood at the far end of the hall, speaking quietly to the Sealkeepers. Every so often, one of them would glance my way. Not subtle. “You feel it too,” Kael said under his breath. “Yes,” I admitted. “It’s quieter… but it’s here.” Nytherion hadn’t spoken since it pulled me under earlier. But the silence didn’t feel like absence. It felt like waiting. I turned toward the breach—and froze. The glow had changed. Before, it was fractured, erratic. Now it pulsed slowly, like a heartbeat. A rhythm. “Uh… Elara?” Cassian’s voice had lost its usual edge. “That’s new.” The mages on ward duty had gone rigid, the
Dawn never came quietly in the fortress. There was always the changing of the guard, the scrape of boots on stone, the hiss of torches being doused. But that morning, the sounds felt sharp, brittle—like the fortress itself was holding its breath. The breach chamber had not emptied all night. I could feel the exhaustion radiating from the mages as they kept the wards burning, their lips cracked from chanting, their eyes ringed with shadow. Kael stood beside me, a solid wall of heat and steel, while Cassian paced like a caged animal on my other side. Corren faced us from across the chamber, the Sealkeepers flanking him. Behind them, the fissure glowed faintly—not the furious light from last night, but something steadier, more deliberate. That was worse. “Your condition is unstable,” one of the Sealkeepers said, voice muffled under the silver mask. “The breach responds to you in ways our wards cannot counter. It is no longer a question of if—only when.” Kael stepped forward, bristli
I didn’t remember leaving the council chamber. One moment I was locked in Corren’s gaze, the Sealkeepers’ silver masks reflecting my own too-bright eyes back at me. The next, I was in the corridor outside, my breath ragged, the fortress walls pressing in like they were trying to crush the air from my lungs. Cassian was beside me. Or maybe in front. It was hard to focus. “Elara.” His voice cut through the haze. “Hey. Stay with me.” I blinked, and for a heartbeat, it wasn’t him I saw. It was Nytherion. Not in its full, shifting glory, but a fragment—like someone had poured starlight into a human-shaped mold and then cracked it down the center. Its “eyes” weren’t eyes at all, just infinite dark. “Don’t let them cage you,” it whispered. “You’re not a prisoner. You’re the threshold.” I shivered. Cassian’s hand tightened around my arm. “What is it saying?” I shook my head. “Nothing I plan on listening to.” But even to my own ears, it sounded thin. We kept walking, but the air was
